Tire shredder. We make crumb rubber with our own hands using a homemade crusher. How to make a rubber shredder with your own hands. Making rubber crumb with your own hands at home

Every year, thousands of tires go to landfills and landfills, despite the fact that for an enterprising person they are a free resource from which crumb rubber can be produced.

If it was needed only once, you can buy it in the right amount from manufacturers.

But where can you get crumb rubber if you need it on an ongoing basis and in large quantities?

Consider purchasing your own tire recycling equipment.

However, not everyone can afford a full-fledged installation, and such an investment will not be profitable for everyone. The way out is to create equipment with your own hands, and use it to produce crumb rubber from tires at home.

Recycling small amounts of rubber at home

If you need very little raw materials, you can do without equipment at all.

This will require only scissors and a cutter.

The metal cord is first removed from the tire, then it is divided into strips and crushed into smaller fractions to the required size.

At this point, the process is considered complete.

Material for the design of paths, flower beds or a separate playground is ready to use.

But to get more raw materials or have an income from tire recycling at home, you need the right equipment.

Tire crusher construction

Three main methods of crumb production are used:

Tire crushing after cooling with liquid nitrogen to -190 degrees.
Obtaining crumbs on industrial equipment of a full cycle with the removal of the cord and subsequent grinding of rubber.
Recycling using universal crushers, which you can do yourself at home.

The first two methods require large investments. The third option is available to anyone who has the ability and desire to make a crusher at home.

The necessary units can be made independently in the workshop or at the production site - where there are metal-cutting machines (turning, milling) and a welding machine for the manufacture of component parts.

If you cannot independently perform the machining of blanks and you have to order them according to your own drawings, the cost of tire processing machines will still be several times cheaper than similar purchased units.

The main component of the tire recycling line is a shredder (rubber grinder). Let us consider in more detail the purpose of the nodes of this machine.

Unit device

The machine consists of the following main units:

electric motor 5 kW - 2 pcs;
housing with disc shafts;
lattice;
worm gearbox - 2 pcs;
shredder frame;
loading bunker;
guide tray;
control cabinet.

Details of the installation are mounted on a powerful frame welded from channels.

Box with cutting discs

The main unit of the crusher for rubber is the body with milling rolls.

At the same time, the cutting knives are made of high-strength steel and heat-treated, which significantly reduces their wear. They practically do not require sharpening during operation.

The calculation of the openings of the box, shafts and cutting elements must be accurate, so it must be done by a specialist in this field (designer).

Grid for crumb calibration

In order to obtain a calibrated fraction of tire raw materials, shredders are equipped with a special grate, which is installed under the rolls.

Worm gear

The rotation of the shafts with disk cutters is carried out separately, directly from the worm gearboxes connected to the electric motors through couplings.

The gear ratio is selected from 25 to 35 so that the cutting is without sticking and at a sufficient speed.

Machine frame

The frame is welded from profile elements, ensures the reliability and stability of the unit during operation, as well as loading and unloading operations.

loading hopper

The tire recycling plant is equipped with a tire loading hopper and a tray for removing finished crumb rubber.

Thanks to its design, the hopper eliminates the formation of blockages from the raw materials and guarantees a directed movement of the mass towards the rotating rolls.

Tire cutter

The tire cutting and cord removal plant consists of a carrier frame and a stand.

On the carcass is a tire clamping mechanism that rotates with the tire during cutting. The engine speed is reduced due to the different diameter of the pulleys. There is a built-in wedge-shaped cutter on the stand, which is adjusted to a certain size by moving the quill.

How to grind tires?

The technological chain consists of several preparatory stages before the production of the required fraction is obtained.

This procedure includes:

Inspection and removal of foreign objects from the tire cavity.
Cord cutting.
Cutting the tire into strips of 50-80 mm in size.
Grinding of raw materials by means of a shredder.
Separation and separation of metal from textile parts.
Calibration of crumbs into fractions using a vibrating sieve.

Equipment performance

The work of these two main units during the processing of tires is done in a semi-automatic mode.

For the normal operation of this line, a room of about 150-200 square meters is required. meters. This is due to the fact that you need a place for the location of not only equipment, but also for storing worn tires, finished tire products and metal waste.

The output of rubber crumb on this equipment per hour will be approximately 200-800 kg and up to 100 kg of scrap metal, 2-3 unskilled workers will be needed to service the machines.

In addition to tires, this equipment can process other rubber (conveyor belt, cameras, gas masks). The output is a crumb with sizes from 0.7 to 4 mm, while it is 65-85% of the total mass of raw materials.

Where to apply the obtained raw materials?

Rubber crumb can be:

The price of crumbs will depend mainly on the quality of raw materials, and secondarily on the fraction.

The most popular is the crumb, the fraction of which is 2-4 mm.

It's great for creating:

The popularity of such crumbs is due to the fact that the minimum amount of glue is used to glue these granules. A polyurethane binder is sometimes 5-8 times more expensive than crumbs.

Conclusion

Building a DIY tire crusher is a good idea for those who want to make their own rubber crumb but aren't ready to spend tens of thousands of dollars on equipment.

You can create a chopper with a carpentry workshop, as well as certain skills and materials, or use the services of people who specialize in this.

The crumb obtained at home can be used for your own needs or sold to enterprises and the public.

Making rubber crumb with your own hands at home

In recent years, the use of crumb rubber and materials made on its basis for decorating sites, organizing paths, and covering roofs of houses has become fashionable. You can also use crumb rubber to create waterproofing for building foundations. In order to use crumb rubber elements on your site, you can contact a company that professionally works with crumb rubber. However, working with this material is not so difficult. If desired, and if you have free time, crumb rubber can be made at home with your own hands.

What is rubber crumb made of?

There are two ways to go about solving this issue. Path number one relies on the transition of rubber to a brittle state at low temperatures. If at home it is possible to cool the source material for preparing crumbs to a temperature of -70 ... -80 degrees Celsius, then it will be possible to obtain crumbs from any type of source materials. However, solving this problem at home is not so easy.

Path number two is the competent selection of source material. As we know, crumbs can be obtained from tires and tubes from car wheels. But tires are very difficult to grind under normal conditions, and it is also difficult to extract the metal cord from them later. For this reason, to obtain crumb rubber at home, it is better to use old worn-out cameras as raw materials. This material can be easily cut with the help of improvised tools available in any home.

How to make crumb rubber at home?

At the initial stage, it is necessary to prepare a sufficient amount of raw materials, i.e. old car cameras and the appropriate cutting tool. For the manufacture of a coating with an area of one square meter and a thickness of 10 mm, about 8 kg of crumb rubber is needed. In the production of crumbs from old chambers, the loss of material by weight is minimal. Thus, it is necessary to prepare the source material at the rate of 8 kg of old cameras per 1 square meter of coverage.

To grind rubber, you can use ordinary scissors or an ax. If desired, you can build special guillotine shears. In extreme cases, you can organize the cutting of cameras with a fairly sharp knife.

Crumb production must be performed according to the following algorithm:

Remove all metal elements from the old camera
Cut the camera into thin strips
Thin strips obtained in step 2 grind

Tire recycling at home

Every motorist knows that the disposal of used tires is a serious problem. However, recycling tires at home has several options. Let's consider some of them.

Creativity

There are many examples of the creation of original sculptures from used tires, used to decorate the garden, or as an independent work of art. Garden variations can be embodied in the form of swans, garden vases, etc.

The "pattern" is extremely simple and understandable. And the created images are very similar to living prototypes.

There is also a more artistic attitude to rubber waste. From them, as from clay, the conceived sculpture is literally “molded”. You can, for example, sculpt a horse, and, moreover, such a hot one that will cause the approval of other venerable sculptors.

Pragmatic Approach

Yet for most, tire recycling at home involves the use of waste rubber for the benefit of the home and its economy. There are several nuances here.

Firstly, you can use used tires for the home, as they are.

Secondly, the product of their primary processing obtained at small and large enterprises can be used in the household.

Thirdly, it is possible to organize a production within the framework of a private, home-based company, which is engaged in the actual primary processing of tires.

Using tires as an eternal material

Tires are known to be one of the finest building materials. Some craftsmen used tires from Belaz as a support, a foundation under a garden house. And prudent owners can use tires as elements:

fence
mini flower beds
playground elements

Application of partially recycled rubber

Tire recycling is carried out in stages:

cutting and crushing
plasticization and exit to the final product

Crumb rubber is a semi-finished product used for various types of production. You can make fuel out of it, or you can make tiles, moreover, both for asphalt and for roofing. It is also used for the production of shoes, sports ground surfaces, etc.

In the household, you can even use a crumb in the form of a semi-finished product - it is sprinkled with paths along the lawns. You can also use rubber roofing for your home.

Waste tire recycling

Tires are crushed - either in a state cooled to -70 ... -80 degrees, when the rubber becomes brittle, or at normal temperature - but with a more powerful tool. To obtain fuel, rubber is subjected to a pyrolysis operation.

This is an environmentally hazardous process. Equipment, space maintenance, organizing the collection of raw materials and finding buyers, attracting significant funds - all this is completely associated with a small "private shop" where tire recycling would be profitable.

Conclusion

As part of a car enthusiast's household, recycling tires is quite difficult. To do this, you need to be a very big enthusiast. But maybe you will be lucky enough to find a unique way to use bad tires.

technology for processing car tires, tires and other rubber, description and video of the manufacturing process

The service life of car tires is quite short, after which they must be replaced.

Disposal of worn-out tires is a big problem for the ecology of the whole world.

Every year the number of used cars increases by almost 10%.

Obviously tires need to be recycled.

In this article, we will consider the following questions:

what is the technology for processing crumb tires;
what equipment is used;
where rubber crumb is used;
Is it possible to make it yourself.

Tire recycling methods

Not only worn-out tires, but also any other used rubber products can serve as raw materials for rubber crumb production.

In practice, only two main methods are used to obtain crumb rubber from used tires:

shock wave;
mechanical.

Let's consider both methods separately.

shock wave

This technology for grinding car tires and other rubber waste into crumbs was invented relatively recently.

The processing process consists in cooling products to ultra-low temperatures, followed by crushing by a shock wave.

Cryogenic chambers are used for freezing, and the shock wave is formed by a special electrical device or by detonating a small amount of explosive.

This technology for recycling used car tires requires the installation of expensive equipment, which is economically viable only for large enterprises with large volumes of raw materials.

Mechanical

This is a classic technology for processing tires into crumb rubber, which, unlike the first, is used everywhere.

The essence of the process lies in the phased mechanical action on the raw material to obtain the required fraction of crumb rubber and by-products.

There are several methods for recycling tires by mechanical action:

grinding at normal temperature;
at high temperature;
with cooling of raw materials;
using the "ozone knife";
by forcing raw materials with a powerful press through special dies.

The most popular method is conventional mechanical grinding at normal temperature.

This technology is classic and is great for organizing small enterprises for recycling used car tires.

Classic tire shredding technology

With the necessary equipment, this technology makes it possible to obtain crumb rubber of any fraction up to a dusty substance.

The whole tire recycling process can be divided into several stages, each of which uses a certain type of machine tools and mechanisms.

The main technological stages of crushing tires and the types of equipment used in each of them:

At the first stage of processing, tires are sorted by size, which is necessary to adjust the equipment for certain tire sizes. Crushing itself begins with cutting the side rings on a special punching machine.
The second stage of tire shredding takes place using hydraulic shears, mechanical cutters or guillotines, which are used to cut into strips and pieces of medium size.
The crushing process continues in a special shredder, where large pieces of rubber are crushed into small chips ranging in size from 2 to 10 square meters. cm, which arrive at the next technological operation.
At this stage, the final grinding of raw materials to the required fractions takes place. Rotary mills with square blades or other equipment capable of withstanding enormous mechanical loads are used.
After complete grinding of used tires, it is necessary to separate the resulting crumb rubber from by-products: chopped metal court and textile waste. For this, magnetic and air separators are used.
At the final stage, the resulting rubber crumb is passed through a special vibrating sieve, where the separation into fractions takes place. The resulting material is packaged and sent for further processing.

This is the classical scheme of the technological process of crushing tires into crumbs at normal temperature with an approximate list of machines and mechanisms.

The number of processing stages can be reduced or increased depending on what equipment will be used and what kind of crumbs you need to get at the exit.

Transportation of raw materials from one technological operation to another can be carried out both manually and automatically.

If the movement of tires, pieces of rubber, chips and rubber crumb is carried out using belt and screw conveyors, then the whole complex of equipment for recycling old tires, in fact, becomes a production line.

For the organization of a small recycling workshop, the installation of an automatic line is the best solution.

What equipment is needed?

There are a lot of offers on the tire recycling equipment market.

Russian and foreign manufacturers offer both fully equipped lines and plants, as well as individual machines, devices and mechanisms. The price will depend on the type and performance of the unit.

Consider the minimum set of what is needed for recycling tires into crumbs.

Bead removal machine

This is the first unit in the entire technological chain of tire grinding. Its purpose is to remove the landing rings from the tire.

The principle of operation of bead removal machines is based on:

cutting down;
cutting;
pulling out the landing rings.

Each of the methods does not have any advantages over the others.

Further processing of the removed rings is carried out on pressing machines, where the metal base is squeezed out and the remaining rubber is crushed in the general flow.

Tire shredders without bead

shredders;
tape cutters;
hydraulic shears;
roller milling devices;
mills.

The production line may include several such devices:

Hydraulic shears and tape cutters cut tires into large pieces.
Shredders process them into smaller fragments.
Roller aggregates and mills bring the type of raw material to the required fraction.

Metal and textile separators

The magnetic separator removes the chopped remains of the metal court from the crumb rubber.

The principle of operation of this device is simple: a powerful electromagnet pulls metal waste from the mass of raw materials and sends them to a receiving hopper.

Removal of textile residues takes place in a cyclone-type air separator, where a powerful air stream simply blows light textile fluff into a receiving hopper.

Read more about textile and metal cord, as well as where it can be used with benefits, read here.

Vibrating screens for separating the product into fractions

Tire recycling complexes include at least two vibrating screens: coarse and fine cleaning.

On the first device, large, not completely processed, pieces of rubber are screened out, and on the second, the standard fraction of rubber crumb is separated.

A vibrating sieve is a device consisting of a table with holes corresponding to the crumb fraction to be separated, and a mechanism that vibrates the table at a certain frequency.

Conveyors and other mechanisms and devices

Tire recycling lines and plants include belt conveyors to move tires, pieces of rubber and crumb rubber from one process step to another.

Some manufacturers use screw conveyors in their lines to move and pack finished crumb rubber. In addition, automatic tire recycling lines are equipped with bunkers, security systems and process control.

All of the above equipment is equipped with automatic lines for processing old tires into crumb rubber.

The number of machines and mechanisms depends on the volume of production and the final type of product that needs to be obtained as a result of processing.

What can be made from the obtained granulate?

Crumb rubber itself, obtained by recycling old car tires, is an intermediate product. Raw materials, depending on their fraction, are used in the manufacture of the following products:

floor coverings for indoors and outdoors;
curbs, bumpers and speed bumps for road facilities;
substrates and pads to protect goods during transportation;
figures for playgrounds;
building materials - waterproofing and noise-absorbing;
dielectric products for the electrical industry;
MBR - bitumen-rubber mastic.

Granulate is also added to asphalt mixtures, obtaining a strong and durable road surface.

From fine crumbs, it is possible to produce various rubber products by hot pressing, namely:

bushings;
videos;
rubber shoes;
many other goods.

In addition, it can serve as an additive in the manufacture of new tires, thereby reducing its cost.

The entrepreneur receives not only rubber crumb, but also grinding by-products: metal court and textiles, which are also liquid goods. They can be sold and get additional profit.

As you can see, there are ample opportunities for the tire recycling business in terms of marketing products, because the need for it is very high in many industries.

Making crumbs from tires at home

Tire granulate can be easily purchased in online stores, building supermarkets or ordered directly from the manufacturer.

But for those who want to open their own small home business or just make a pavement for the paths in the garden with their own hands, the issue of self-production becomes relevant.

In this case, it makes no sense to purchase expensive equipment for the processing of tires.

There will be no problems with raw materials for making rubber crumb at home. It is enough to walk around the neighbors, who will gladly take out the used tires from the garage and get rid of them.

The simplest set of equipment and tools for grinding tires and other rubber products can be made by hand with minimal investment.

As mentioned above, rubber can be crushed mechanically or by freezing to a low temperature.

The latter option for the home is unacceptable, since it will be necessary to purchase an expensive low-temperature chamber to cool the raw materials.

For the home, the best solution would be mechanical cutting and grinding rubber to a crumb state. In a separate article, we told how to make equipment for these purposes.

Conclusion

Rubber crumb is a multifunctional material necessary for a person in many fields of activity. Its huge plus is that it can be made from old tires, thereby giving a second life to obsolete products.

Recycling rubber is easy, equipment for this purpose is available everywhere.

How do you think, how can you make money on some types of household waste, not counting, of course, services for its disposal? For example, on old, unnecessary car tires? It should be noted that there are really a lot of options.

Just like plastic bottles, tires can be used to make garden decorations (flower beds, animal figurines, swings, sculptures, and much more). In general, collecting (or buying up) and recycling car tires turned out to be a very profitable business, especially if you approach it with a certain amount of imagination and using various modern technologies.

Based on the fact that such a large amount of raw material remains unclaimed, it can be said that competition in this type of business is relatively small, even miserable. And finally, the most important thing is that the products obtained as a result of the processing of automobile tires are in high demand now, and will be in demand for at least another hundred years. So, if you wish, you can pass your established business to your grandchildren.

People have long begun to think about the recycling of used tires from cars, which increase by a huge amount every year. But no solution has been found. Of the total number of used tires, only a fifth is recycled. There are only recycling points for these old tires. By helping to improve the environment, you can earn extra money on this.

Worn-out car tires are quite valuable polymeric materials. A ton of used rubber contains about seven hundred kilograms of rubber that can be reused, for example, as fuel, various rubber technical products and building materials.

At the same time, if such a ton of tires is burned, then two hundred and seventy kilograms of soot and four hundred and fifty kilograms of toxic emissions will violate the environment. It is unprofitable and very difficult to recycle tires economically on the scale of a large industry. But, according to manufacturers of mobile equipment for recycling, such production in a mini-enterprise can be a huge success and a good profit.

Such a small factory is a prefabricated equipment, which covers an area of about eighteen square meters, its height is ten meters. This equipment is capable of processing about five tons of consumables per day.

Moreover, the production area includes warehouses for worn materials (plastics and tires), an area for the preparation of raw materials (cutting tires into pieces), as well as a warehouse for finished materials such as liquid fuels, carbon black, and scrap metal storage.

What can be obtained from the old "rubber".

What is most surprising is that the process of recycling automotive rubber is itself a final process, leaving almost no waste behind. Let's see what you can get as a result of recycling old tires:

Rubber crumb, which is used in the production of various gaskets and seals (including for sanitary purposes), shoe soles, rubber mats, rubber roofing (you can find out about liquid rubber for roofing here), Novotek seamless coatings, as an additive to asphalt , filler for punching bags, and for many other purposes.

Equipment for recycling tires and rubber to the plant: installation

The need to recycle used tires arose due to the rapid growth in the number of cars in most developed countries. The number of used tires is growing every year, so the problem of their disposal has become an acute problem for the authorities of the states. Tire recycling equipment is not cheap.

Special factories and enterprises for their processing are being built. They solve the environmental and economic problem associated with the disposal of obsolete car tires. This waste tire business is already growing by leaps and bounds today. First of all, this is facilitated by a large amount of inexpensive raw materials.

A tire processing plant is being built near the place of sale of the product obtained after processing, namely: rubber crumb, saw, steel cord, fuel oil. A tire recycling plant is a cost-effective solution to the problem. It is located at the place of accumulation of raw materials or near the plant, the production in need of recyclables. The main thing is that the tire recycling plant should be located at a distance of more than 300 meters from the located residential buildings.

The plant is equipped with special equipment for the production of crumb rubber. To open a business in this area, investments are needed, however, due to the small number of competitors and the demand for this raw material, all investments pay off in the near future.

Waste Tire Recycling Equipment

Equipment for rubber processing is a plant - a reactor. It is installed in a specially designated open area.

Medium tire shredding equipment has the following capacity:

2 tons of liquid fuel
1.5 tons of solid residue containing carbon
0.5 tons of steel cord
1 ton of gas

The volume of tires to be shredded is 5 tons per day. Processed products serve as raw materials for many types of production. The reactor itself operates using gas, which itself is capable of producing during the processing of used tires. The installation is low maintenance, it only needs two people for one shift. To work on such a plant, employees of the enterprise need to undergo special training and study the features of the process.

Tire recycling products include:

Rubber granulate and crumbs. Rubber crumb comes in various fractions: 0.1 - 0.45 mm.
Regenerate. Finely ground crumbs with improved quality. Dimensions: 0.6 - 10 mm.
Chips. Size 2 - 5 cm. Represented by pieces of tires along with steel cord.
Resinoplast. Used in the manufacture of soft roofs.
Rezinopol. Represented by a floor polymeric covering.
Bireplast. It is represented by a multi-layer waterproofing roll roofing material.
Reisol. Represented by rubber with a waterproof adhesive layer of rubber.
Fiber concrete. A mixture of crumb rubber and two types of cord: textile and metal.

Rubber processing technologies

Rubber recycling can be done in several ways. The choice of method ultimately determines the appearance and demand for the resulting product. The paragraph will not deal with landfilling. Despite the fact that this option is the simplest, at the same time, the crumb plant causes the least harm to the environment.

There are four main recycling methods:

Crumb production - equipment for the recycling of tires into crumbs is considered the most rational, it can process several tons of tires per year and brings a stable income to the owner. But the technology is not perfect, it has a significant number of disadvantages, such as the need to select raw materials with the same composition to standardize the properties of the final product.
Pyrolysis is the decomposition of tires under the influence of high temperature. This method is extremely inconvenient because during this process a huge amount of toxins released into the atmosphere is released. Another obvious disadvantage of this method of disposal is economic unprofitability. Decomposition equipment is expensive and pays for itself in a significant amount of time.
Incineration - is the complete destruction of tires. The only benefit from such an action is the production of energy, however, such products do not act very well as fuel. This is due to the fact that during combustion a large amount of soot is formed, which over time makes the equipment (furnaces) unusable. Since rubber contains sulfur, when using this disposal method, the substance enters the atmosphere and, when interacting with water, sulfuric acid is formed.
Recovery is a process similar to recycling. This is the most promising and rational way. So, in the manufacture of one new tire, approximately 30 liters of crude oil are consumed, and only 5 are needed for restoration.

In recent years, business in this area has been gaining momentum, it is especially popular in European countries, since it is there that society takes environmental protection most seriously.

Another clear advantage that this business is famous for is the purchase of inexpensive equipment for processing tires into crumbs. You can organize a recycling plant with your own hands in any room, even in your own garage.

Tire crumb line

The tire recycling line produces crumb rubber for business, it is considered environmentally friendly due to the absence of emissions into the atmosphere or into the ground.

The line and all equipment must be made in accordance with the requirements of the Russian Federation, which were put forward for equipment of this type:

The level of noise emitted.
By the amount of harmful emissions.
According to life safety.
Accordingly, the safety of waste processing.

The whole line for processing tires into crumbs consists of sectors:

Preparatory, which includes 2 machines: 1 - for removing bead wire, 2 - shears for cutting tires.
Crusher, consisting of 1 - crushing chamber and 2 - return sifter.
Crushing rollers, representing two drums that rotate at different speeds towards each other.
Granulator that feeds the mixture from the feed funnel to the crushing zone.
Vibrating table of a magnetic selector for uniform distribution of the mixture under the influence of vibration.
Knife granulator, consisting of a body with knives, a shaft with knives, a mesh with a hole diameter of 4 mm.
Vibrating table in the form of an inclined rectangular structure.
Magnet for picking up fine wire residues.
Textile separators for a high level of crumb removal from textiles present.
Automatic packers filling bags with crumbs.

This is how the process of recycling tires into crumbs, which serves as a secondary raw material for further production, looks like. It is not difficult to organize this recycling business. This is due to the relative cheapness of equipment and fast payback periods. The main mission of this business is to protect the environment.

Recycling old tires at home

Recycling tires into crumbs at home and at the factory

It should be noted that this rubber waste is a flammable material, and if a huge number of tires ignite, they can pose a threat of poisoning to everyone nearby, since rubber, when burned, releases carcinogenic toxins, such as benzpyrene. Storage in landfills leads to the reproduction of rodents and insects, which are sources of dangerous infections. To avoid the deterioration of the environmental situation in Russia and abroad, proper disposal is required, namely waste processing.

Without constant recycling, an environmental crisis could set in very soon.

Recycling

Powder from waste of larger fractions is used in the production of composite roofing materials, rubber-bitumen mastic, waterproofing materials, and rubber coatings. Scrap metal is obtained from a metal cord, which is also used by Russian entrepreneurs.

Also, textiles and rubber are obtained from tires.

Recycling at home

According to one of the scenarios, the rubber should be cooled to a temperature of approximately -75 ° C. Agree, not everyone has such an opportunity. So let's use the traditional scenario:

Take the cameras
Remove all unnecessary elements from them
Cut them into thin strips
Grind those stripes

The rubber grinder in this case is an ax or scissors.

Mechanical processing method

The most professional way.

The technological line is a sequence of installed working devices, overcoming which the material becomes a finished product.

Processing into crumb rubber goes through three stages:

Today, there are a sufficient number of manufacturers of this equipment on the Russian market.

Chemical processing method

In conditions of strong cooling, the rubber acquires a glassy state. Crushing of rubber occurs when struck with a special hammer.

After grinding, textiles and metal are removed from crumb rubber.

Recycling of automobile tires to obtain crumb rubber is carried out in several stages: Note that the processing of rubber can be both crumb and diesel fuel. But the latter option requires serious material investments. This process consists of sorting and subsequent grinding of tires, and then the selected and prepared material is loaded into a special reactor, which extracts fuel from recycled materials at high temperatures.

Utilization and recycling of car tires

Let's see what can be obtained as a result of recycling old tires: crumb rubber, which is used in the production of various gaskets and seals (including for sanitary purposes), shoe soles, rubber mats, rubber roofing (you can learn about liquid rubber for roofing here) , Novotek seamless coatings, as an additive in asphalt, a filler for punching bags, and for many other purposes.

Business Idea: Tire Recycling

Its waste is released into the environment.

This is not a good solution, but the emission resembles the exhaust gases of a truck.

As for the remaining mass, it passes through a magnetic separator, in simple words, it is sifted through a sieve. Metal elements are screened out and sent to the warehouse.

Fuel oil is transported by a conveyor to tanks, in which the fuel will be stored until shipment.

Tire recycling: step-by-step opening of production

Therefore, the choice is obvious: it is better to recycle used tires and get paid for it than just burn them, causing harm to the environment.

Based on the chosen method of tire recycling, different products can be obtained: Let us consider the process of tire recycling using the example of crumb rubber production, which has a wide range of applications. So, the process consists of the following steps: In the future, the resulting crumb can be converted into fuel / gas / fuel oil.

Recycling hazardous types of waste in Russia is relevant. With an increase in the number of cars, the number of used tires is growing (according to statistics, it reaches 1 million tons per year).

There are not enough enterprises involved in their processing, although each region annually accumulates 50 tons of worn-out rubber. Not all cities have places to store this type of waste. Discarded tires are found on the side of the road or near suburban roads.

The Moscow region has the greatest experience in the recycling of tires (2 specialized plants operate), but they process only 10%. Therefore, the tire recycling business will occupy an empty niche.

The advantage of such a business is the ability to get old tires for free. Recycling tires into crumb rubber is a promising type of business.

In Russia, there is no system for recycling tires, experts attribute this to the imperfection of the legislation.

Advantages and disadvantages of the processing business

The benefits of this business include:

inexpensive raw materials in large quantities;
location near the places of sale;
few competitors;
the ability to use any room;
economic benefit.

Disadvantages:

initial investment required;
selection of raw materials with the same composition.

Room selection

The main parameter is the area of the premises and the cost of rent. When choosing a room, consider:

the area must be sufficient to accommodate production equipment;
places for loading and unloading;
necessary support facilities;
connection to water supply and power lines;
convenient access roads;
distance from the residential area of 300 m or more.

An industrial area located outside the city will be the most suitable place.

Required documents

To open a business, you will need documents confirming or, the conclusion of the sanitary-epidemiological and fire service, an agreement for the supply of electricity. The licensing of this type of activity was canceled by the Federal Law No. 93 dated 06/25/2112.

What documents are required for registration of an individual entrepreneur and how to properly issue them in accordance with the requirements of the law - read

Activity registration

The choice should be approached responsibly: this affects the registration procedure, payment of taxes and other factors. When opening an LLC, the responsibility arises:

as a legal entity;

Starting a business requires large investments, which scares aspiring entrepreneurs. You can use a bank loan or receive a subsidy under the state program. To do this, you need a business plan with calculations.

and tips for implementing them are contained in our new article at the link.

Possible risks

The production cycle includes the supply of raw materials, the operation of equipment and the sale of finished products. Risks that may arise:

breakdown of technological equipment (to reduce this risk, it is necessary to maintain the line in a timely manner, follow the recommendations for its operation, replace worn-out mechanisms, consumables);
interruptions in the supply of raw materials (it is possible to conclude a contract for the supply of raw materials simultaneously with the search for equipment);
sales difficulties (a long-term contract should be concluded with an enterprise that needs rubber crumb and a distribution channel should be established to nearby regions);
damage to products during storage (special conditions are not required, however, crumb rubber is afraid of moisture).

A business based on the processing of car tires into crumbs will turn out to be profitable if the entrepreneur manages to resolve the issue of marketing finished products. This direction is promising, consistently brings good profits.

It has long been known that worn-out tires that are out of service are a potential source of environmental pollution and environmental damage. Recycling tires into crumbs at home is the same popular method, along with factory ones. Rubber waste from used tires is virtually non-biodegradable, taking hundreds of years to decompose.

Recycling

Recycling is also economically beneficial. From car tires, you can get various types of valuable recyclable materials, as well as produce a huge amount of finished products. From the waste of powder rubber of a very fine fraction (about 0.2 mm), new car tires and rubber shoes are produced, this secondary resource is popular in Russia and the CIS countries.

Recycling at home

Especially active and advanced people have the opportunity to process rubber with their own hands. What is needed for this? Spent chambers, tires, tires and a little ingenuity. Recycling tires into crumbs at home is a rather complicated undertaking. According to their properties, cameras from old tires are more suitable. They are softer and more easily amenable to external influences.

According to one of the scenarios, the rubber should be cooled to a temperature of approximately -75°C. Agree, not everyone has such an opportunity. So let's use the traditional scenario:

Take the cameras
Remove all unnecessary elements from them
Cut them into thin strips
Grind those stripes

The rubber grinder in this case is an ax or scissors.

Mechanical processing method

The most professional way. The technological line is a sequence of installed working devices, overcoming which the material becomes a finished product.

Processing into crumb rubber goes through three stages:

Tire preparation. Initially, they are washed and cleaned of impurities, after which they are transported by a conveyor to the primary crushing unit, where they are ground with knife crushers to large pieces (30-50 mm).
At the second stage of the technological process, the primary processed raw material is fed by means of a belt conveyor to a hammer crusher, where it is crushed again to smaller sizes (10-20 mm). It is at this stage of processing that the metal and textile cord, bead wire is separated from the rubber. Textiles are separated by a special textile removal system, and metal is separated by a magnetic separator. The collected metal waste is then briquetted.
At the final stage, processing into crumbs is already underway. As equipment for processing tires into crumbs, an extruder is used - a grinder, in which the rubber mass is ground into a fine powder. At this stage of tire processing, additional cleaning of crumbs from textiles and metal is also carried out using a gravity separator. After that, the crushed rubber crumb is divided into fractions and packed in polyethylene bags of 20 kg or in big bags (soft containers) with a carrying capacity of up to 1000 kg.

Today, there are a sufficient number of manufacturers of this equipment on the Russian market.

Chemical processing method

With the chemical method of processing, automobile tires are subjected to pyrolysis. With this processing method, the thermal decomposition of rubber into its constituent elements occurs. Tires are pre-crushed into a homogeneous mass and sent to an oven, where they decompose at a temperature of 500 - 800 ° C. This procedure lasts 10 - 20 minutes. In the process of thermal decomposition of rubber, about 50% hydrogen and 26% methane are formed, as well as solid pyrolysis products, which are then used in wastewater treatment at wastewater treatment plants in Russia.

There is also an effective, but expensive physical and chemical method for processing tires into crumb rubber - cryogenic grinding of car tires. Crushing of rubber is carried out in a special cooling chamber at extremely low temperatures (up to - 120 ° C). A refrigerant (liquid nitrogen) is supplied to this chamber, cooling to ultra-low temperatures. In conditions of strong cooling, the rubber acquires a glassy state. Crushing of rubber occurs when struck with a special hammer. After grinding, textiles and metal are removed from crumb rubber.

In modern times, there are many mini-factories for the processing of tires. The business plan for recycling car tires is quite simple. Its implementation will require modern tire recycling equipment, warehouse equipment, fuel tanks, tools and overalls for workers, as well as equipment installation costs. It is necessary to register an enterprise and a license that will allow you to engage in this type of activity. Starting this business will require significant start-up capital.

Every year, thousands of tires go to landfills and landfills, despite the fact that for an enterprising person they are a free resource from which crumb rubber can be produced.

If it was needed only once, you can buy it in the right amount from manufacturers.

But where can you get crumb rubber if you need it on an ongoing basis and in large quantities?

Consider purchasing your own tire recycling equipment.

Recycling small amounts of rubber at home

If you need very little raw materials, you can do without equipment at all.

This will require only scissors and a cutter.

The metal cord is first removed from the tire, then it is divided into strips and crushed into smaller fractions to the required size.

At this point, the process is considered complete.

Material for the design of paths, flower beds or a separate playground is ready to use.

But to get more raw materials or have an income from tire recycling at home, you need the right equipment.

Tire crusher construction

Three main methods of crumb production are used:

Tire crushing after cooling with liquid nitrogen to -190 degrees.
Obtaining crumbs on industrial equipment of a full cycle with the removal of the cord and subsequent grinding of rubber.
Recycling using universal crushers, which you can do yourself at home.

The first two methods require large investments. The third option is available to anyone who has the ability and desire to make a crusher at home.

The main component of the tire recycling line is a shredder (rubber grinder). Let us consider in more detail the purpose of the nodes of this machine.

Unit device

The machine consists of the following main units:

electric motor 5 kW - 2 pcs;
housing with disc shafts;
lattice;
worm gearbox - 2 pcs;
shredder frame;
loading bunker;
guide tray;
control cabinet.

Details of the installation are mounted on a powerful frame welded from channels.

Box with cutting discs

The main unit of the crusher for rubber is the body with milling rolls.

At the same time, the cutting knives are made of high-strength steel and heat-treated, which significantly reduces their wear. They practically do not require sharpening during operation.

The calculation of the openings of the box, shafts and cutting elements must be accurate, so it must be done by a specialist in this field (designer).

Grid for crumb calibration

In order to obtain a calibrated fraction of tire raw materials, shredders are equipped with a special grate, which is installed under the rolls.

Worm gear

The rotation of the shafts with disk cutters is carried out separately, directly from the worm gearboxes connected to the electric motors through couplings.

The gear ratio is selected from 25 to 35 so that the cutting is without sticking and at a sufficient speed.

Machine frame

The frame is welded from profile elements, ensures the reliability and stability of the unit during operation, as well as loading and unloading operations.

loading hopper

The tire recycling plant is equipped with a tire loading hopper and a tray for removing finished crumb rubber.

Thanks to its design, the hopper eliminates the formation of blockages from the raw materials and guarantees a directed movement of the mass towards the rotating rolls.

Tire cutter

The tire cutting and cord removal plant consists of a carrier frame and a stand.

How to grind tires?

The technological chain consists of several preparatory stages before the production of the required fraction is obtained.

This procedure includes:

Inspection and removal of foreign objects from the tire cavity.
Cord cutting.
Cutting the tire into strips of 50-80 mm in size.
Grinding of raw materials by means of a shredder.
Separation and separation of metal from textile parts.
Calibration of crumbs into fractions using a vibrating sieve.

Equipment performance

The work of these two main units during the processing of tires is done in a semi-automatic mode.

The output of rubber crumb on this equipment per hour will be approximately 200-800 kg and up to 100 kg of scrap metal, 2-3 unskilled workers will be needed to service the machines.

Where to apply the obtained raw materials?

Rubber crumb can be:

The price of crumbs will depend mainly on the quality of raw materials, and secondarily on the fraction.

The most popular is the crumb, the fraction of which is 2-4 mm.

It's great for creating:

The popularity of such crumbs is due to the fact that the minimum amount of glue is used to glue these granules. A polyurethane binder is sometimes 5-8 times more expensive than crumbs.

Conclusion

Building a DIY tire crusher is a good idea for those who want to make their own rubber crumb but aren't ready to spend tens of thousands of dollars on equipment.

You can create a chopper with a carpentry workshop, as well as certain skills and materials, or use the services of people who specialize in this.

The crumb obtained at home can be used for your own needs or sold to enterprises and the public.

scheme for creating a homemade grinder for PET

Polymer materials have become very firmly established in our lives and now they can be found in any industry.

But due to the fact that these materials do not decompose naturally, they cause serious damage to nature.

A positive feature is the possibility of their recycling.

To do this, the plastic is first prepared and brought to the state necessary for this, it is crushed. To do this, special devices were invented - crushers (shredders, machine tools, shredders) for plastic. You can make such a crusher with your own hands.

Varieties of choppers

In total, there are three types of such devices, which differ in the possibility of processing a particular polymer material.

They are divided into options:

The design looks like V-blades on scissors and is suitable for shredding plastics such as acrylic, film and nylon.
A type that is used primarily in plastics factories and recycling plants.

By design, they are of several types: hammer, cone or jaw crushers. They are used for processing large-sized plastic products, like a window profile.

The most common option has a rotary design and is used to process thin-walled plastics like bottles, foam.

The plastic shredder will allow its owner to contribute to the environment and even earn money. For domestic purposes, a rotary version of the crusher is usually used. Its design consists of a rotor on which the knives are securely attached.

Crusher Mesh

After switching on (and it can work both from a liquid-fuel engine and from a conventional electric motor), the axis with knives begins to rotate and, as a result, under fast and strong blows, the raw materials that have got inside such a device are crushed.

At the bottom of the body for grinding there is a grate, which has a certain mesh size. It is determined depending on what diameter the fraction should ultimately have.

The raw material in the device is processed until it reaches the desired size and exits through this sieve.

Specialist note: the quality of the metal of the knives used should be used as strong as possible. It is best to use high-quality hardened steel so that the blades wear out less quickly and the sharpness of the knives lasts longer.

Materials and tools

To assemble such a device at home, you will need certain skills in working with a welding machine.

The total plastic shredder consists of such elements as:

circular saws. The optimal number is approximately 20 pieces.

Since this is the basis of the entire apparatus, they should be selected only with high-quality and various tooth configurations, which will allow better grinding of waste;

as a drive, it is best to use an electric version of the engine. The reason is a wider choice and the ability to use not only outdoors, but also indoors;
axis for fastening saws;
to create a frame and frame, you will also need a metal profile;
various elements for fastening;
a hopper through which the material will be fed for processing and a protective cover;
to connect the rotor you will need a special belt, as well as a pulley and several bearings.

Incorrect choice of crusher saws can lead to an imbalance on the axis, due to which the structure will vibrate strongly and wear out faster.

Process of creation

Schematic diagram of plastic crusher

After preparing everything necessary for work, you can begin the manufacturing stage:

First, a cutting block is made by putting circular saws on a pre-prepared axis. In order to leave the necessary space between such impromptu knives, it is worth using nuts.
Next, we mount the structure on the pulley and ensure free rotation due to the bearings.
Now we make a rectangular frame and a support frame from prepared metal materials.
The next step is to weld the height-adjusted legs, also using welding.
Further, the frame is covered with a steel sheet, for this we weld it to the frame. We make a hole of the required size in it and mount the engine at the correct distance from the cutting elements. The protective cover and material supply container are necessary for safety and work efficiency.
After creating the frame, we begin the last stage of assembling the plastic crusher. To do this, a so-called protective cover and a bunker are put on the knives, through which the raw material will be fed. During the installation of the casing, it is worthwhile to provide a hole in it for connecting the axis to the pulley.
The final touch is the connection of the cutting block to the motor shaft using a belt for this. Everything, the design is ready.

The main recommendation given by experts is the need to draw up a drawing of how the planned structure will look like before starting work. This will make it possible to avoid inaccuracies and inconsistencies in the dimensions of individual parts.

Having designed and assembled such a unit with your own hands, you can, knowing its entire design, easily make changes and refine it.

The shredded plastic will have the size that is laid down in the design capabilities of the unit itself.

When choosing a power unit, it is necessary to determine in advance how often the device will be used. If the work on it is rare and the loads are insignificant, then a low-power electric motor will suffice, but for active use, a more powerful option and with a large number of revolutions will already be required.

And in order not to have to collect the processed fractional material on the floor, it is advisable to provide a place under the saws for attaching a special container in which it will be collected.

Do-it-yourself plastic crusher for recycling

Polymeric materials have firmly entered modern life, and there is not a single industry where they are not used, from the production of containers to space technologies. Every year, about 180 million tons of various plastics are produced on the planet. Most of them cannot independently decompose into simple components and be disposed of on their own.

This brings irreparable damage to nature and can cause an ecological catastrophe. A positive feature of almost any polymer (plastic) is the possibility of recycling, so that old plastic things can get a “new life” as useful items. Recycled plastic is slightly inferior in terms of strength characteristics to the primary polymer, but with certain proportions, products made from recycled plastic practically do not differ from the original.

Varieties of choppers

Before being recycled, any plastic must be shredded. For this, there are special devices - crushers. Depending on the physical qualities of the polymer placed in them, the devices can be classified into several categories:

for shredding PVC film, nylon or acrylic. The design resembles large scissors with "V"-shaped blades;
for large plastic waste. Most often used in recycling plants or plastics factories. There are hammer, jaw or cone designs. With their help, window profiles and large parts and cases are crushed;
for PET bottles and thin-walled plastics. The most common version of the grinder, structurally called rotary.

The required type of apparatus can be purchased or made by yourself. This is a small household appliance from the third category. Do-it-yourself plastic crusher is quite easy to do and does not require serious knowledge and specialized tools, except for a welding machine.

Learn more about rotary shredder

The most common design is the impact crusher. It consists of a rotor on which the knives are fixedly fixed. Under the action of a driving force - from a diesel, gasoline engine or an electric motor, the axis with knives sets in motion and grinds the raw materials that have fallen under the knives with quick blows. Depending on the purpose, there are low-speed machines and high-speed units.

At the bottom of the working chamber, a sieve or grate with a certain mesh size is installed, depending on the required quality and diameter of the obtained fraction. Raw materials are cyclically processed by knives and gradually pass through a sieve.

Particular attention is paid to the quality of the metal from which the knives are made - it must be a good hardened steel, which prevents rapid wear and ensures that sharpening is maintained for a long time.

We make our own crusher

There are several of the most popular varieties of plastic shredders that are made at home. In order to assemble this device with your own hands, you will need a little patience and minimal skills. As a special tool, you only need a welding machine or a household inverter.

A do-it-yourself plastic crusher, the scheme of which will differ slightly depending on the skill level of the manufacturer and his imagination, has the following common elements:

drive unit. The most commonly used electric motor. Thanks to a large selection and affordable prices, you can choose the model of the required power. In addition, the electric drive crusher is quieter and can be used both outdoors and indoors;
circular saws. This will be the basis of our apparatus. It is necessary to select a sufficient number of them and a different configuration of teeth for better grinding of waste. The optimal number of saws on the axis is about 20;
the axis on which the saws will be attached;
metal profile or pipe for the manufacture of the support frame and frame of the crusher;
protective cover and feed hopper. They can be made independently at home from galvanized sheet metal with metal scissors, a hammer and a vice;
a pulley, two bearings and a special belt, with which an interaction is created between the electric motor and the rotor;
fasteners (nuts, washers and self-tapping screws for metal).

When all the necessary materials and tools are prepared, you can begin to manufacture the unit.

First of all, you need to build a cutting block. To do this, we put circular saws on the prepared axle. The diameter of the axle and the seat of the saw must match. There should be a minimum distance between improvised knives, which is provided by ordinary metal washers. At the ends of the saw should be well fixed with nuts. Then we install the axle on the pulley and use two bearings so that the structure rotates freely.

The next step is the manufacture of the supporting frame. We make a rectangular frame from a metal corner, profile or pipe by welding. Then we weld the legs of the required height to it. We cover the frame with a sheet of metal, which is welded to the frame. We cut a hole in the sheet equal to the size of the cutting block. We mount the engine at a short distance from the knives.

After the frame is ready, you can proceed to the final stage of assembling our device. To do this, we put a protective cover on the knives and install a hopper on top for supplying raw materials. A hole must be provided in the casing through which the axle will be connected to the pulley. Using a special belt, we connect the motor shaft and the cutting block. Our simplest plastic crusher design is ready.

People who have extensive experience in the manufacture of various units with their own hands recommend that they first draw up a drawing of the future design. In this way, you can avoid size mismatches or miss a node or part.

Before purchasing an engine, you should decide on its power and output speed. For infrequent use and at low loads, a compact electric motor of low power is sufficient. The more actively the crusher will be used, the more powerful and “resourceful” the motor should be.

Circular saws are better to choose light-alloy ones. They are slightly more expensive than standard products, but they retain their sharpness much better, which will save you from regularly and often removing the cutting block to sharpen saws. The design itself should be thought out in such a way that you can easily get to any of its nodes.

For greater convenience, you can make a special container where the processed raw materials will be located. The container is fixed directly under the saws of the crusher. If you need to receive recycled plastic of various sizes, you should take care of manufacturing and installing a special mesh or grid under the disks with the desired cell size.

Small Conclusions

A plastic crusher is a tool that will not only help fight environmental pollution, but also bring some income to the owner. Shredded plastic can be handed over by weight to recycling points and earn some money. In addition, depending on the design of the cutting unit and the power of the motor, the device can be used to grind leaves and branches - and this is already a serious help to any summer resident or owner of a private house.

The assembly of the unit is not particularly difficult, and thanks to your own developments, you can improve the design. Assembled independently, the crusher will not differ in any way from mass-produced grinders for household needs, and in terms of reliability it will surpass cheap Chinese counterparts. One of the options for what a plastic crusher can be - a video story is attached.

We make a garden shredder with our own hands on circular saws

After spring tree pruning, most gardeners are faced with the problem of disposing of old branches. If you are a thrifty owner who is used to using all the waste, then most likely you send all the branches to the compost heap. There, all this stuff rots and in 3-4 years you are guaranteed to receive an excellent organic fertilizer - compost. All this, of course, is wonderful, but too long. If you first chop the branches and leaves on them, then your compost will ripen in a season, or even in a couple of months. And here a garden shredder can come to your aid - a device that will turn the source material into chips or flour. The devices that are on sale are not cheap, so we suggest that you familiarize yourself with the instructions for making a garden shredder with your own hands.

We will make such a bandura ... let's go!

We will not convince you that a homemade shredder will be completely free. Naturally, some details will go into its manufacture, which will cost money. However, on average, a home-made unit will cost you 2 times cheaper than a ready-made chopper of a popular brand. Judge for yourself, for the chopper you will need:

Circular saws - 15-25 pieces
Motor - gasoline or electric
Stud (rod) M20, washers and nuts to it
Pulley (for example, from a VAZ generator) and a tight belt
Bearings
Metal pipes for the frame
Sheet Metal for Hopper
Plastic washers 14-24 pieces

Crushing of material in the garden shredder is carried out with the help of knives. In finished models, the knife is most often a metal disc with 2-3 cutting surfaces. A large amount of work quickly makes the teeth unusable and they have to be sharpened periodically - you see, this is not very convenient, and besides, it takes your time. If you decide to make a garden chopper with your own hands, then you can not repeat these design flaws, but assemble a reliable, high-performance and, most importantly, durable knife.

We suggest using carbide-tipped saw blades for this. It will take not one disk, but several to collect a system from them - a package. In ready-made garden shredders, the knife, as a rule, has a thickness of 3 cm, but we can pick up a package of any thickness - everything will depend on the number of saws purchased. On average, for a quality knife 6-10 cm thick, you will need 15-25 pieces. Each disc has many teeth, originally designed to cut through hard wood. Therefore, grass stems, leaves and branches for them will be the same as seeds. As a last resort, if the teeth on the saw become dull, there is nothing to stop you from going to the nearest tool store and getting a replacement for it.

Circular saws can be successfully used as chopper knives

However, the knife is not everything. In order to set it in motion, we need an engine. For fast chopping of branches in small volumes, it is easier to use an electric motor. Its use may seem somewhat inconvenient due to the cable and the need to connect to an outlet, but it works almost silently and does not emit exhaust gases. The walk-behind tractor has more power, so it is ideal for those cases when you need to crush coarse material often and for a long time.

1. Saws are assembled on an axis, the diameter of which is determined by the bore diameter of the discs (20mm). For this, a stud with an M20 thread is suitable. Accordingly, washers and nuts of the same diameter will be needed.

Saws assembled on the axis of the future chopper

If we install discs on a hairpin close to each other, then the knife will not work. And here's why: the width of the saw teeth is greater than the width of the blade itself, so when rotating, the teeth will cling to each other. To prevent this from happening, it is necessary to separate the disks a short distance. This is easy to do with homemade washers that you can cut out of thin plastic. Their number should be 1 piece less than the number of circular saws.

2. A pulley is put on the stud axle (from the VAZ generator or from the pump). To rotate the axis, two VAZ intermediate shaft bearings with an inner diameter of 20 mm are also used.

3. A frame is welded from profiled metal pipes, on which the walk-behind tractor bar is attached. The engine is mounted on the frame so that it can be moved relative to the circular saws. This is necessary to change the tension of the drive belt if necessary.

An axle with circular saws is attached to the frame

4. For ease of use, a thrust bar made of a metal profile is fixed on the frame, into which branches and stems will rest during crushing.

5. The cutting block must be fitted with a metal casing that is welded from sheet metal or cut from galvanized steel. For reliability, it is better to use the first option.

The casing is better to be made of sheet iron - it is more reliable!

6. Another hopper with a socket is attached from above to load the material to be crushed. There are no special requirements for this part, so most often it is made of flexible galvanized steel.

The receiving hopper is easy to make from galvanized steel

Unlike factory models, a homemade chopper does not require an overly careful attitude. It will become a universal helper in the household and will help not only to chop branches and other household waste, but also to crush fruits (apples, pears, plums), and along with the seeds. This is very convenient if you need to make jam, puree or homemade wine when the fruits are crushed to a paste.

Garden shredder in action

The circular saws that form the blade of the unit are capable of processing fairly large pieces of wood. Of course, we are not talking about logs, but branches with a diameter of 10 cm will be quite “too tough” for him. This home-made shredder compares favorably with the factory product, the body of which simply will not let large parts of the material through. Accordingly, you will significantly save your time, because you do not have to sort the branches by size and think about what to do with too large fragments. Also, it will not be necessary to monitor the moisture content of the material, while the purchased grinder requires adjusting the degree of dampness of the feedstock. The fact is that in most modern ready-made shredders, the electric motor is located at the bottom of the structure, so when processing wet stems, moisture will inevitably get into the engine, and this will lead to breakdown. In a homemade product, you are free to decide where to install the engine, in the version described above, it is located horizontally, on the same level as the knives.

It is also worth paying attention to the cost savings when using a homemade chopper. Firstly, manufacturing will initially be cheaper than buying a factory device, and secondly, a “home-made” will not need to purchase expensive parts in the event of a breakdown - all of its elements are not expensive.

Homemade garden shredder is able to crush even large branches, turning them into chips

In addition, a homemade garden shredder has a high performance. All waste loaded into the hopper will be pulled in by the circular saws and disappear at an incredible speed. Thus, a home-made device can be no worse than an expensive and modern garden tool. In a word, if the chopper is really needed, but there is no money to buy it, there is only one way out - to make it yourself!

Each of us knows that a vehicle cannot do without tires. However, not everyone thinks about where the worn rubber goes. There are two ways: either the tire is sent to a landfill and thereby pollutes the environment, or it is recycled. It's safe to say that rubber is a dangerous pollutant, so they always try to dispose of it. For this simple reason, there are all the prerequisites for creating your own small plant, where tires will be processed.

What everyone should know

Every year the number of cars on the roads increases by about 5-10%. Based on this, the amount of worn rubber increases by about 1 million tons. In many countries, the issue of recycling is very acute. You can partly solve this problem if you set up your own small production. You have several business development options. For example, it can be the processing of car tires into fuel oil or crumbs. If you want to get fuel, you will have to spend a little more money, since the production line is quite serious. Pay attention also to the fact that you can work not only with tires, but also with plastic products, which will slightly increase the profitability of the enterprise. This business has several undeniable advantages, now we will consider each of them.

Firstly, you do not need to inject a lot of money into the purchase of raw materials. This is due to the fact that worn rubber is thrown away. Local authorities, if they, of course, are worried about the ecology of their city, will deliver everything to you. But that's not all, as the municipality is ready to pay for the fact that your company will process car tires. Agree, getting almost free raw materials, and even making a profit from the fact that you are doing this business, is not bad at all. Of course, everything does not end there, since our main goal is not only to save the environment, but also to make a net profit. Fixed assets will come from the sale of the same fuel oil, which is an extremely popular type of fuel in agriculture. By the way, you can also get free raw materials at tire fitting points, which are more than enough in big cities. The thing is that service station employees, etc. pay additional funds for the removal of old tires and their disposal.

Recycling rubber tires: pros and cons

It is impossible not to say a few words about the fact that this niche has not yet been fully filled. The number of entrepreneurs in this area is relatively small, about 20% of the optimal figure. This means that only a fifth of the worn rubber is disposed of and recycled, the rest goes to landfill. You must understand that 1,000 kilograms of burned tires is 450 kg of various toxic gases, as well as 250-270 kilograms of soot. But if the same amount of rubber is properly disposed of, then about 700 kilograms of full-fledged rubber can be obtained from mining, which can be used to make fuel and rubber products. It hardly makes sense to talk about the industrial scale of the enterprise, but it is very possible to establish a small tire processing plant.

The complex itself is relatively small, but its size directly depends on production volumes. So, for processing 5 tons per day, you need a room of 18 squares and 10 meters in height. There must be a warehouse on the site where you will store tires, plastic, etc. There must be a site for the preliminary preparation of raw materials (cleaning, cutting rubber). You can not do without a room for storing finished products. In this case, it all depends on what exactly you get. It could be fuel and so on. For example, for fuel oil, you will need to purchase several large-capacity tanks. They don't have to be new, it's even better to buy used, it's much cheaper. Please note that recycling rubber tires is a difficult and dangerous business. Therefore, technology must be carefully observed. Let's talk about this in more detail.

Technological process

In fact, there is nothing complicated here, but it is necessary to control the process at all stages of production. At the very beginning, you have to start collecting tires. Then you must take them to the warehouse of your enterprise for further processing. In order not to damage the scissors, which, by the way, are not cheap, it is necessary to inspect all raw materials for the presence of metal objects, such as discs or rings. As for the cutting tool, ideally it should be hydraulic shears, but this is not at all necessary, we will talk about this a little later. Next, the crushed rubber is sent to the reactor - a special tire recycling plant that operates at a given temperature, most often 450 degrees Celsius. Decomposition leads to the fact that we get several semi-finished products, such as gas, metal cord, fuel fraction.

The same gas is used to support combustion in the furnace as a by-product fuel. Its waste is released into the environment. This is not a good solution, but the emission resembles the exhaust gases of a truck. As for the remaining mass, it passes through a magnetic separator, in simple words, it is sifted through a sieve. Metal elements are screened out and sent to the warehouse. Fuel oil is transported by a conveyor to tanks, in which the fuel will be stored until shipment. It should be noted that the plant for the processing of tires, which allows you to get pyrolysis fuel, is quite expensive - about 2 million rubles. Its productivity is about 5 thousand tons of raw materials per day, which is quite a lot.

Production of crumb rubber

And here is another rather interesting idea that has not received proper distribution to date. The essence of such a business is that you will sell shredded and processed rubber, which can be used for different purposes. In order for you to roughly understand what we are talking about, it is necessary to give general indicators in numbers. Thus, a ton of crumb rubber on the Russian market will cost no more than 20,000 rubles. As for the main consumers, these are construction companies, manufacturers of rubber products, roofing materials, coatings for building and sports tools, etc. In principle, it is quite easy to find a point of sale.

It is also necessary to take into account the fact that approximately 700-800 thousand tons of worn tires are thrown away on the territory of the Russian Federation every year. Approximately 20-25% is disposed of properly, everything else is either simply lying in landfills or burned. So, the processing of tires into crumbs can bring 5-8 billion, but this is already an industrial scale. If you are going to be doing this kind of recycling at your plant, then you will need a mechanical crusher. will have to be changed very often, which leads to high costs. Another disadvantage of this idea is that a lot of electricity is consumed, about 500 kilowatts per ton of finished products. Nevertheless, recycling auto tires in this way will be beneficial. But only if you receive appropriate support from the state.

Tire recycling equipment

Separately, we need to talk about what our production line will consist of. In principle, there is not so much equipment, and it is not complicated at all. Nevertheless, the price "bites". The main unit is a tire recycling plant (reactor), 10 meters high, 3.5 meters wide, 5 m long. This unit must be installed only in an open area, that is, under the open sky. You, as a future entrepreneur, must understand that you will have to pay quite a lot of money for electricity. The reactor itself consumes about 6 kW per hour. In addition, there are also scissors - 7-8 kW / h. In principle, this is practically all the equipment that is necessary to start production. What else is needed is a few crucibles to unload the resulting material.

As noted above, the reactor has a capacity of about 5 tons per day. But of this mass, approximately 40% will be liquid fuel. The fact is that as a result of decomposition, you will get gas (about a ton) and somewhere around 0.5 tons of steel cord. We should not forget about the solid residue (carbon-containing materials), which is approximately 30% of the total output. It is worth paying your attention to the fact that the processing of old tires in the reactor is carried out continuously. All you have to do is add tires. Combustion is supported by the gas produced inside the furnace. The reactor should be operated by two specially trained specialists. In principle, training courses can be completed fairly quickly. Now let's go ahead and look at a few more important points.

How much money do you need to get started?

This is one of the main aspects that interests absolutely all beginners. You don't need to spend a lot here. If you are going to purchase used equipment (reactor, shears), you can save up to 20% of the total amount. It is worth taking such a step or not, it's up to you. There is no guarantee that a used reactor will not fail after the first heat. In this case, no one will compensate you for the damage. One million rubles should be enough for everything about everything. This includes the cost of a reactor with a capacity of 5 tons / day, as well as shears. In addition, you will need to purchase several tanks (60 tons). If these are used containers, then you will have to pay about 25,000 rubles apiece. How many pieces you need, think for yourself, but you do not need to be limited to one or two tanks. The fact is that the processing of tires into fuel is a seasonal business.

During the period of a decline in fuel prices, it is better not to sell it, but only to accumulate it. When the period of increase comes, and this will happen for sure, you can get a good income by selling all the fuel oil at once. This tactic works and is considered quite effective. But this does not mean at all that you should completely freeze sales, it is enough to reduce them by 50-75%. You still have to pay employees. Four specialists will cost about 60,000 rubles a month, and tools and overalls - another 50,000. There are also regular monthly costs: electricity, taxes, rent, etc.

About the income of the enterprise

As you can see, tire recycling technology is quite simple. There are no fuel additives, complex chemical reactions and other points. Moreover, as noted above, the raw materials are completely free. Sometimes even collecting tires can make some money, which will pay off the monthly electricity costs. If you live in the outback, then it is unlikely that you will be paid for disposal, but in big cities the situation is completely different. There are many industries that pay good money to recycle rubber. This is due to the fact that many city dumps refuse to accept such waste. For the processing of a ton of tires, you can get a different amount, from 2 to 5 thousand rubles.

It is safe to say that even recycling tires at home will bring a good income. Thus, consumers are ready to pay 3,000 rubles for a ton of low-quality carbon. Scrap metal is accepted at the rate of 4 thousand rubles per ton, and fuel oil - 3-4 thousand rubles per ton, depending on the period. By simple calculations, you can come to the conclusion that in a month you will earn about 350,000-400,000 rubles. Approximately 50% must be paid for electricity, workers, etc. With such an intensity, the tire recycling line will pay off in six months, which is quite fast. As you can see, the idea is very interesting and promising, but not everything is so simple. In such a business, as, in fact, in any other, there are a lot of pitfalls. Let's see how not to make a mistake.

Problems when starting a business

It happens that it is simply not possible to find a free piece of land. This is due to the fact that it is necessary to maintain a safe distance to residential buildings, which is 300 meters. The farther the plant is from the city, the greater the cost of delivering raw materials, we should not forget about this. Remember that not everyone wants tires to be recycled under their windows. Feedback from ordinary residents will be negative, even if the reactor is located at a distance of 400 meters from residential areas. For this simple reason, look for a place on the production site. Most likely, you will find it, since quite a few sites are empty. All that is required of you is to negotiate directly with the company, as a rule, this is not so difficult to do. At least, it is much easier than to conclude an agreement with firefighters and a sanitary and epidemiological station.

Do not forget that you need a license to get a permit is not difficult, since tires are non-hazardous materials (4th group). But the catch is that your production officially pollutes the atmosphere. Most likely, you will be asked (forcibly) to buy a treatment plant. Its price is usually several times higher than the entire plant. But there are several ways that will help you delay the purchase for a certain time. Experts say that it is not advisable to open an enterprise for the processing of any one material. Like it or not, decide for yourself. In any case, you can always expand your workshop and melt glass, plastic or metal there. According to statistics, 75% of entrepreneurs encounter environmentalists who are wary of this kind of production.

A few important details

As noted a little above, you will encounter the fact that the item "contingencies" will appear in your business plan. This is due to the fact that it will be necessary to resolve issues with environmentalists and firefighters. For example, to store fuel oil in new tanks, only a protective shield is needed, but used tanks require additional protection. There are special lines for fuel and gas, and fire safety instructions for personnel, and much more. In any case, you need to have a reserve in your budget of several hundred thousand rubles. This will save you a lot of trouble. The expense items are quite large, but we have already considered them, and you probably know what you will be dealing with.

Do not forget that you, as a manager, must not only observe how your employees work, but also perform a number of other equally important tasks. Among these: the constant development and growth of the boundaries of the enterprise, accounting and tax accounting, as well as the adjustment of goals and plans for the near future. In this article, one important point was not mentioned - advertising your product. There are several options here. One of them is to create your own thematic site where you can offer fuel oil, etc. Nobody has canceled ads on poles, stops and stands. Until now, this is a good and effective method to loudly declare yourself. In addition, for a nominal fee, you can rent a billboard and place your advertisement there. By the way, you need to do it wisely. It is important not to overload with unnecessary information, but also to attract the attention of a potential audience.

Conclusion

So we talked with you about what tire recycling is and how to open such a business. As you can see, everything is quite simple, but there are a lot of important points. Sometimes it happens that it is difficult to find a supplier, or the latter refuses to just give away old tires and demands money for them. In principle, you can find another, more acceptable enterprise, where they will only be happy to get rid of excess garbage, and they will even give you money for the road. Sometimes it makes sense to conclude a full-fledged long-term supply contract. So you can eliminate downtime for your business and increase income. But all these points should be discussed directly with the supplier. Remember that it is much more difficult to find a point of sale for tires than a businessman who is ready to buy this garbage. This is due to the fact that in some cities there are no tire recycling reactors at all.

If you get good fuel oil, then aim at city or private boiler houses. There you will be happy to purchase fuel, which is vital for heating water. If you are going to get crumb rubber, then you will need a machine that costs about 500,000 rubles. The cost of electricity per 1 ton of products - 90 kW. The disadvantage of this approach is that a group of knives (40 pieces) wears out after processing hundreds of tires, so they often need to be changed. In principle, for one knife you need to pay only 30 rubles, which is relatively little. So, a unit with a capacity of 20 tires per hour pays off in about six months. The results are the same as in the production of fuel oil. But in the first case, there are fewer problems with environmentalists and firefighters, since we are not dealing with either waste into the atmosphere or liquid fuel. Well, in principle, and all on this topic. The most difficult thing is to start, and then it will be much easier.
