DIY grain crusher drawings 9. Grain crusher from a washing machine. Which grain crusher is better: hammer or rotary?

Homemade grain crusher (grain crusher) - it's simple and reliable device for grinding grain into flour. Made from scrap materials, motors of power tools, household appliances, it will make it possible to provide livestock and poultry with high-quality compound feed and sufficiently finely ground feed flour.

At the same time, the cost of assembling such a grain crusher is 2-3 times lower than that of factory analogues, and the feed obtained with their help is not much inferior to purchased food. This makes a homemade grain crusher very profitable in economically device.

You can assemble a grain crusher using an angle grinder (grinder) with a disc size (diameter) of 115 or 125 mm as an engine.

The assembly process of such a device consists of the following steps:

A rectangular or round base is cut out of waterproof plywood 8-10 mm thick with a jigsaw.
In the center of the base is done round hole for the grinder gearbox.
Diagonally from the central hole on the base, another hole is made for the grain bin.
The chopper knife is made from hard high-carbon steel 1.5-2.0 millimeters thick.
If necessary, the knife is released over the fire and a hole is drilled in the center for mounting on the gearbox shaft of the grinder.
Using sandpaper, the knife is sharpened.
The grinder is placed on the base, its round protrusion is placed in a pre-cut hole.
Using a homemade clamp made of metal tape and two screws, the angle grinder is secured to the base.
A sharpened chopper knife is attached and fixed to the grinder shaft.
The old pan is cut in half, holes are made in its bottom with a 4 or 5 mm drill;
The resulting sieve is secured to the base on the knife side using 4 corners, rivets or screws.
The assembled grain crusher is placed on a capacious container - a bucket or large metal pan. A plastic 5-liter bottle with a cut bottom is inserted into the hole for the grain bin.

During operation, the angle grinder is connected to the network, a locking button is installed on the handle constant speed knife To obtain flour, grain is poured into a homemade receiving hopper - plastic bottle.

In this case, to regulate the flow of grain, a movable tin valve is inserted into the neck.

Make a simple and productive grain crusher from an old activator machine vertical type(“Oka”, “Volga”, “Fairy”) can be done as follows:

The squeezing device is removed from the machine.
With the washing machine on its side, unscrew the fixing (locking) screw or bolt on the activator pulley.
Having installed the machine in the working position, the activator is removed along with the shaft.
A plate of galvanized sheet metal of the appropriate size and shape is attached to the activator niche.
The shaft is unscrewed from the activator.
A trapezoidal knife is cut out of an old circular saw and rapid blade, the diameter of which is slightly smaller or the same as that of the removed activator.
The knife is sharpened using sandpaper and secured to the shaft with two nuts.
The shaft with the attached knife is inserted into the hole in the tank and secured in the pulley with a locking screw.
To collect the final grinding product - flour - the drain hole at the lowest point of the tank is widened using a hammer and chisel, and a piece is inserted into it steel pipe and brought out at an angle.
To prevent large particles from getting into the final product, a fine-mesh filter is installed in front of the hole for collecting flour at an angle of 60-700. steel mesh or a sheet of galvanized sheet with holes with a diameter of 4-5 mm.
To load grain into the removable lid of the machine, widen the existing hole and insert a 5-liter plastic bottle with a cut bottom into it.

The advantage of such a homemade grain crusher is that its assembly does not require drawing up a drawing or making a base for the engine.

In addition, it has good stability, has a spacious tank (up to 30-40 l) and low electricity consumption.

Grain crusher from a vacuum cleaner

To make a simple and reliable grain crusher, working but unused Soviet vacuum cleaners such as “Raketa” and “Saturn” are used.

The production of such a grain crusher is carried out as follows:

The motor in the housing is removed from the vacuum cleaner.
The chamber with the suction impeller is removed from the engine shaft.
A round base is cut out of thick sheet steel.
A hole is cut out in the center of the base for the motor shaft, and a hole is made on the side for the grain bin.
The motor housing is secured to the base using screws and brackets.
A trapezoidal pre-sharpened knife is attached to the motor shaft.
A sieve made from an old saucepan with 4- or 5-mm holes in the bottom is attached under the knife.

For comfortable work of such a unit it is mounted on a container special clamps, short self-tapping screws.

Important! The hole into which the grain bin is inserted and through which raw materials are supplied for grinding must be located in the rotation zone of the chopper knife. If the rotation zone of the knife does not completely cover the feed hole, not covering 1 centimeter or more, most of the grain will spill out and not be crushed, thereby clogging the sieve.

Depending on the grinding method, design and location of the working parts, there are 4 types of grain crushers:

Rotary– grain crushing in such devices occurs due to a rotor located horizontally and moving at high speed.
Hammer– the design of such grain crushers includes a rotating vertical drum and stationary hammers located in a circle, against which the grain is crushed. When grinding in this way, the finished flour is poured down and, passing through a sieve, ends up in a container placed under the deck of the housing.
Roller– crushers crush grain due to 2 rollers located in one chamber, rotating towards each other. At the same time, the gap between them is so small that the incoming raw material is not simply crushed, but, due to high speed, is crushed into dust. The advantage of such devices over others is the ability to crush grain with high humidity.
Millstones– grain grinders, in which grain crushing occurs when it gets between two discs (millstones) located with a small gap. In this case, one disk rotates at high speed, and the second is stationary.

Among these varieties, the most common are rotary and hammer – they are more productive, reliable, easier to repair and maintain.

Crushers for home use

Among factory-made grain crushers, the following models are most suitable for private farms:

"Three Little Pigs 350";
“Farmer ISE-05”;
"Cyclone-350";
"Bison 400";

Important! The average cost of a factory installation, depending on power, performance and brand, ranges from 2000-2300 to 6200 rubles. Assembly homemade device if there is unnecessary work washing machine, an old vacuum cleaner, an angle grinder will cost only 500-1000 rubles.

Grain crusher performance

Performance – the most important characteristic grain crushers, which indicates the amount of grain they grind per hour (kg/h).

For homemade and factory models, the average is:

Homemade units - up to 150-200 kg / h;
Factory models - from 180 to 400-500 kg / h.

Moreover, in most cases, the productivity of factory crushers cannot be increased, while any home-made unit this characteristic can be significantly improved by changing the power unit (engine) to a more powerful one.

Conclusion

A homemade grain crusher, with some minor costs for its production, very quickly pays for itself.

It is useful not only for private owners of large households, but also for medium and small farmers, individual entrepreneurs and companies involved in mixed feed.

A small own grain crusher is very useful device for any farmer. With the help of a grinder you can make food for rabbits or poultry, grind feed from grain for livestock or chop vegetables and fruits. In addition, the grain crusher can be used to make flour from grain for yourself, which is important for residents of rural areas. Knowing how to make a grain crusher with your own hands according to drawings and videos, you can make farming easier.

Making a grain crusher from an old vacuum cleaner with your own hands

The cost of crushers sold on the market is quite high, so it makes sense to make it yourself. You will need some tool, unnecessary Appliances or its parts that are still working. The motor from an old but still working vacuum cleaner is suitable for making a small grain crusher with your own hands. Below is step-by-step instruction for the manufacture of grain crushers.

Do-it-yourself drawing of a grain crusher

Step 1. To make the base of the future crusher, take a sheet of plywood and cut out a square with sides of 30 cm. Attach the motor from the vacuum cleaner to the base so that the shaft protrudes 4 cm down.
Step 2. The most important thing in a grain crusher is the knife that will grind everything. It uses a strong metal plate with dimensions HxLxW 1.5x20x1.5 cm. The knife is sharpened like a blade, both front edges are sharpened towards the axis of rotation. A hole is made in the middle corresponding to the dimensions of the motor shaft, and the knife is rigidly attached to it.

Raw materials will enter the crusher from a hopper, which is attached at the base. To control the supply of raw materials, make a small window with a shutter in the bunker. To collect the grinding result, place a container, bucket or any container under the sieve.

How to make a crumble out of an old washing machine

There is nothing difficult about making your own grain crusher from an old washing machine. Its operating principle is similar to that of a coffee grinder: the grain is crushed by knives rotating in a drum. Since washing machines are all different, the principle of manufacturing a grain crusher will be presented below.

How to make a crusher mill with your own hands

For self-made Crusher mills require a rotor and a stator that will work like a millstone. If you think through everything in advance, then you can easily make a crumble on your own.

DIY grain crusher will serve you for a long time, and since it was made by you drawings and videos, then there will be no problems with the repair. In addition, it can be quickly modified at any time to suit the needs that arise, for example, to grind vegetables or fruits rather than grain.

A universal, high-performance grain crusher, made by yourself, that is not inferior in functionality to its analogues industrial production. Popular are designs assembled from a washing machine, as well as using an angle grinder and a motor from a vacuum cleaner.

Such units process barley, oats, peas, corn and can be used for the production of mixed feed. By replacing the elements, you can expand the capabilities of the grain crusher and use it for chopping vegetables and fruits. Make optimal design, guided by drawings and diagrams, a beginner can do it, especially since some options are assembled without welding and plumbing work.

Universal grain crusher Shmel

Using a grain crusher assembled from parts of agricultural machinery, you can grind a bag of grain in 15 minutes. The external brake drum from the DT-75 tractor is used as a base. There are teeth on its inner side. They will engage the driven discs of the clutch. The planter opener disc will replace the front base flange. It comes complete with a hub and bearing. The SUPN-8 beet seeder is used as a grain bunker. And hammers are made from shear plates combine harvester.

The device of a homemade grain crusher

Principle of operation:

1. Start the engine from the mains and warm it up.
2. Filling raw materials into the bunker.
3. Grain processing in the crushing chamber: grinding with knives.
4. Screening through a sieve into the receiving tank.

The degree of grain grinding depends on the diameter of the sieve cells. The equipment can be equipped with a grater knife for chopping vegetables, herbs and fruits.

Chopper base

The drum is trimmed on a lathe to a height of 65 mm. Recess height from inside should be 3 mm and the diameter should be 282 mm. Then the third part is cut in the drum for the hole for the sieve, which must adhere to the arcs welded to the flange and outside drum

Drawing of the shredder base without hopper and bedside table

The flange (1) is ground to size 285+0.5 mm, inserted into the drum and welded. To increase the productivity of the crusher, air intake holes with a diameter of 8 mm are drilled in the hub. In place of the cut part of the drum, attach the sieve with two M8 bolts and the side plate to the surface of the disk in the opener.

Grinder sieve: drawing with dimensions

The hole on the top of the drum is 5.5 x 4.3 cm. A hopper with a valve is fixed in it to regulate the flow of grain entering the chopper. It is installed in the desired position and secured with an M5 bolt and a handwheel. The funnel through which the crushed grain is poured is welded onto the flange (10).

The crusher is secured using an angle. The cabinet is divided into two parts by a horizontal partition. A safety circuit breaker, a warning lamp, a reversing magnetic starter and a power button are installed on top. Tools and replaceable sieves are stored underneath.

Hammer drum

Two plates are welded on top of the shaft, the end of which has a hole with an M10 thread. When disconnecting the drum and shaft, a bolt puller is inserted into it. The axles are equipped with six hammers equal weight with high wear resistance.

Hammer drum: assembly drawing

Holes for rivets with a diameter of 1 cm each are drilled. Washers are used to adjust the axial distance between the hammers. For intensive crushing, they are placed in parallel planes.

When the hammer drum rotates clockwise, the grain is crushed worse and spills out faster. Therefore, in order to obtain small fractions, the reverse mode is turned on, and the degree of grinding is adjusted by replacing the grate.

Crusher balancing

Static balancing of rotating parts is carried out to reduce vibration. This operation is carried out on a special device.

Drum balancing device

The assembled drum structure is installed on top of the knives in a horizontal plane. By drilling out the metal from the plates, the rotor stops evenly.

Assembly instructions

For use in household installation is about to take place small sizes by analogy with the factory-produced Shmel grain crusher. Such a device is equipped with a rotor and is connected to a 220 Volt network.

Table: Assembly step by step:

Step	Photo	Description
1		A 350 W (1500 rpm) motor with capacitors is used. A drum with hammers mounted in pairs in four places is mounted on the shaft
2		The mesh has holes with a diameter of 4 mm and longitudinal slots for screening out large fractions
3		The mesh is inserted into pre-prepared grooves
4		With a hammer blow, it is firmly secured with a slight shift to the right.
5		A tank made of tin with a square pipe is attached to the inlet of the working chamber
6		The mechanism is designed to regulate grain supply and grinding quality
7		A special valve to limit the grain supply is lowered and raised manually
8		Portable design mounted on legs
9		The drum is closed with a lid

A self-made grain crusher cannot be compared with aggregates industrial scale, but at home it processes 10 kg of raw materials in half an hour.

Grinder grinder

A homemade high-quality crusher can be made from a grinder. In this case, drawings are not required.

Instructions:

1. A base is cut out of a piece of plywood or laminate.
2. Two holes are drilled in it. The equipment housing is inserted into the first, and the receiving hopper into the second.
3. The grinder is secured with a metal bracket and bolts.
4. Instead of a disk, install a knife.
5. A mesh is attached to the bottom of the base.

Grain crusher from a washing machine

The washing machine is not disassembled, but only the plastic activator is unscrewed. For full operation of the device, an additional motor is attached under the top cover with metal plates and corners. And knives are installed on both motors of the washing machine so that they rotate in different directions.

The grain is poured through a hole in the top lid through a funnel. It is made from plastic container with a wide neck or sheet of tin. The grate is attached close to the walls of the drum. The drain is widened to 150 mm with a chisel and a pipe is inserted. A container is placed next to it to collect processed raw materials. All cracks are lubricated with automotive sealant.

The upper motor will operate in aggressive environment. Therefore, it is protected with a metal casing.

An important step is checking the device. To do this, the unit is connected to the mains and the operation is checked for five minutes at maximum speed. And they evaluate the degree of heating of the engines.

Vacuum cleaner grinding equipment

The base is made from a sheet of plywood and a hole is cut in it into which the engine operating shaft is inserted. A knife 200 mm long and 1.5 mm thick is cut from a metal plate. Or use a vegetable cutting disc. It is secured with nuts on the motor shaft.

Grain crusher from a vacuum cleaner: diagram

The working chamber is metal container with a sieve installed in it. A thin sheet of tin 700 mm long is rolled into a ring, the edges are riveted or bolted together. The sieve is attached with the lower edge bent outward. To process not only grain, but also vegetables, removable meshes with cells of different diameters are used.

Raw materials are fed into a working box with a valve, processed and discharged into a receiver (for example, a tin bucket).

It’s great for any farm or farm owner are aware of the usefulness of grain crushers. Only with their help can you successfully feed livestock, especially if there is a lot of it.

Preparing mixed feed is a priority task, since it is absorbed by the animal body much better than all its components separately. Accordingly, animals gain weight better, receive a larger portion of vitamins and other nutrients, and are less susceptible to disease.

But purchasing compound feed from specialized enterprises where it is produced is not only difficult, but also expensive. Therefore, it is much easier to produce it at home, using only your own products - grain and other ingredients.

Moreover, in this case it becomes possible to prepare special feed for each type of animal separately, one that is suitable only for them. But, no matter how responsible the farm owner is in following the recipe, the quality of grinding grain, hay and other additives still matters.

The smaller its fraction, the better for pets.

Therefore, you need to use only the best technology, which will allow you not only to grind the raw materials, but also to prepare them for future use. required quantity and in a form convenient for storage.

Thanks to the developments of domestic enterprises, there is no need to seek a compromise to solve this problem, because an excellent solution already exists.

This is a new generation grain crusher with excellent performance data and good performance characteristics, developed and manufactured at the Chelyabinsk Bioenergy enterprise.

About the manufacturer

Manufacturer of the Shmel grain crusher, LLC Bioenergia and K has been operating in the agricultural machinery market for twenty years. Since 1996, this enterprise has been developing new technologies for processing products and new types of agricultural equipment.

The company carries out development, production, implementation and installation new technology on any farm.

The company owns nine inventions that are used to produce modern feed, including the Shmel grain crusher, which was completely developed by Bioenergiya and K engineers.

It has no analogues not only in Russia, but also abroad, and in many ways differs for the better even from the most successful similar models.

In addition, during the development of this device many factors were taken into account and research results - a grain crusher can produce pine flour, which, in terms of its performance, carotene content and some vitamins, is much superior to the grass flour commonly used in livestock farming.

If you have this grain crusher, then you do not need and, grain crusher,

All developments of the enterprise are aimed at rationalizing, reducing the cost and increasing the productivity of the production of animal feed, the indicators of which are much higher than feed produced using old technology.

But the company achieved the greatest results in the manufacture of equipment and machinery for the production of alternative feed mixtures.

All achievements and inventions that are successfully implemented became possible thanks to close cooperation with the Chelyabinsk Agrarian Academy and the Trinity Academy of Veterinary Medicine.

Specifications and prices

The grain crusher "Shmel" has engine power 11 kilowatts, which reaches speeds of up to 3,000 rpm. It is capable of grinding 2-3 tons of grain per hour, depending on its density and feed speed, but such high productivity is ensured by a three-phase 380 volt line.

This grain crusher is universal - it is capable of grinding not only grain, but also wood - pine needles, birch bark and the like. It also copes well with “dead” waste, hay and reeds - they can be ground to the consistency of cotton wool and added to animal feed.

"Bumblebee" is very reliable. Equally reliable include grain crushers.

The service life of the crusher rotor is about 2,000 tons, the service life of the hammer knives is approximately 60 tons for each corner, so they will have to be changed no more often than once per 200 tons of ground raw materials.

“Shmel”, in fact, is the only grain crusher that does not require any additional accessories for work - its movement around the warehouse or granary is carried out thanks to the built-in rollers, on which it can be transported anywhere.

This is one of the main features of the “Bumblebee” - complete mobility, which is limited only by the length of the power cable. The installation, moreover, can work on any site, even open.

The installation can operate on any area, and in this case there will be no need to use any special tools in order to deliver grain or other product to the receiver. To do this, “Bumblebee” can be transported in the desired direction.

Also, to facilitate the collection of grains in the crusher design a device for collecting, which is included in the kit. With its help, you can simply collect grain directly from the storage location. This is possible thanks to the vacuum that occurs during crushing.

The cost of this grain crusher averages 170,000 rubles, fully equipped.

And considering all the advantages that the Shmel grain crusher has, the price is not that high, especially if you compare it with the prices of similar products not only from foreign, but also from domestic manufacturers.

The delivery set includes the grain crusher itself with a suction device, three sieves with different diameters– 4mm, 6mm and 8mm., starting device, cable 10 meters long, reinforced corrugated hose “Lignum” 3 meters long, bag filler equipped with rollers for ease of movement, with a fabric filter.

Also additionally an adapter for the hose and a loading hopper are supplied, intended for hay and straw to obtain flour from them.

Device

"Shmel" is one of the few grain crushers that capable of recycling a large number of variety of grains and waste. It is capable of grinding almost all types of cereals: millet, wheat, oats, buckwheat. It can also easily handle soft wood and paper. wood chips and even pine needles.

Moreover, it is not afraid of third-party inclusions, which are very often found in processed raw materials - pieces of slate, stones, concrete and even metal particles. The latter do not get into the grinding thanks to the magnetic catcher, which, by the way, is the only difficult part from a constructive point of view.

The design of the grain crusher is very convenient - it can be moved around the warehouse by just one person, the operator. Also, there is no need to attach it to the floor - thanks to its excellent balancing, the grain crusher is as stable as possible and does not move during operation.

This applies not only to the receiving part, but also to the entire structure, which is designed in such a way that it can be placed in any room and this does not affect performance or ease of loading.

The design of the bumblebee grain crusher is quite simple, making it qualitatively different from any similar devices. The simplicity of the design makes it easy to use. All raw materials loaded into the crusher go through two grinding levels in two successive chambers.

It is supplied to the first chamber due to vacuum - the grain is sucked in and moves at a minimum speed. Here it is cleaned from foreign impurities and debris.

Both crushers operate sequentially as grain arrives - first the first, where cleaning and coarse grinding occurs, then the second, where the partially ground product is finally ground.

Bumblebee 750 from the company Bioenergia

Next, along the hose, the ground grain or any of the products is delivered to a bag filler designed for six bags. Full bags can be replaced simply during operation– the operator just needs to turn off the air supply, remove the filled bag and replace it with an empty one.

Also, this part of the device can be replaced with a hopper - a receiver, which will also be filled through the sleeve. If necessary, the crusher is capable of delivering grinding to a height of up to nine meters, so you can fill truck trailers without resorting to the help of third-party devices - augers, belts and loaders.

“Bumblebee” performs all feeding work independently.

The mixture obtained using this crusher contains two times less dust formations than grinding obtained in similar devices, moreover, this The crusher is very clean.

It does not generate dust during operation - the bag fillers are equipped with a special filter, and when replacing the bag, the air flow is completely blocked, also without producing an ounce of pollution. The impact of dust on humans is minimized - there is practically none.

How to do it yourself?

If it is not possible to purchase a factory-made grain crusher, you can try to make it yourself, with your own hands. In fact, almost all the parts necessary for its manufacture can be found at hand, because these are mainly profiles and sheets of ferrous metal.

But, despite the fact that a homemade grain crusher will be cheaper to manufacture than a factory one, it It won't be much more convenient or practical. Also, it is not provided with a guarantee - all the burdens associated with repairs at first fall on the shoulders of its owner.

And it’s clear that drawings won’t help you make anything remotely resembling a product like a bumblebee grain crusher with your own hands. As for much more simple product, in which there are not so many components and expensive parts - there will be no problems with this.

Assembling a Bumblebee with your own hands is not much more difficult than assembling a grain crusher. Below are drawings of a simple, but convenient and not difficult to manufacture product. It has acceptable performance for a small farm and is quite reliable.

Bumblebee at work

As base parts, you can use tractor parts DT-75. For the base itself, the external brake drum of the rear clutch is suitable. The seeder coulter disc, which is equipped with a hub and bearing, can be used as the front flange.

Hammers can be made from finger plates of the cutting apparatus of a combine harvester. As a grain bin, you can use a container from a beet seeder.

Grain crusher layout

In order to make the base of the chopper, it is necessary to cut the drum to a height of 65 millimeters. This can be done using lathe. Also, it is necessary to grind the internal diameter to a size of 282 millimeters, with a height of 3 millimeters.

It is also necessary cut off a third of the drum, so that a sieve could be placed here. It will be supported by arcs marked 8, which in turn will be welded to the outside of the drum and flange 5. The drawing below illustrates the base of the chopper assembly.

Chopper base assembly

opener disc, which performs the function of a flange and is marked 1, must first be adjusted to a size of 285 millimeters, install in the prepared place in the drum and put it on welding.

In the hub marked 2, it is necessary to drill holes in advance for air intake, with a diameter of at least 8 millimeters. This is necessary in order to maintain the required productivity of the crusher.

On the cutting part of the drum you need to install a sieve 7, which must be attached with two bolts 11 to the surface of the disk on the opener.

Hammer drum device

Before making a hammer drum, on top of the shaft 7 need to weld the plates 2. There should be a hole at the end of the shaft with an M10 thread. This hole is necessary in order to install a special bolt puller in its place when the drum and the engine shaft are separated.

In order to assemble the hammer drum, it is necessary to drill out the rivet holes to a diameter of 1 centimeter, adjust the distance between the hammers on the axis using washers, and due to the fact that the hammers will be located in parallel planes, much greater crushing intensity can be achieved.

If such a hammer drum rotates clockwise, the grain will fall out faster and the crushing will be larger. During reverse movement, on the contrary, smaller.

The degree of grinding can only be adjusted by replacing the grate.

Conclusion

Making a crusher at home, definitely will help you save money, because the necessary materials can be obtained almost for free. But as for the performance of such a device, it will never reach the level of a factory product. Moreover, the level of the Shmel crusher.

Maintaining a personal subsidiary plot is accompanied not only by land work, but also keeping livestock and birds. However, for animals to be productive and healthy, they need proper nutrition, which consists of preparing high-quality feed. You can purchase ready-made feed, but their cost is significantly higher than that of the raw materials themselves, i.e. grains, corn, barley and other types of crops. That is why farmers are increasingly resort to acquisition special technical devices – grain crushers, with the help of which you can process raw materials, thus preparing food for yourself. But there is another way to save money - assemble a grain crusher with your own hands from a washing machine. How to do this will be discussed in our article.

This is especially clear in the example farms, where a large number of cattle, pigs and birds are observed.

Structure of a grain crusher

Principle of operation all grain crushers similar to the operation of a regular household coffee grinder, only on a more global scale. The unit is first plugged into a regular power supply, after which the engine is started. This is very important, because the engine must first warm up before you can start working.

Next, raw materials for processing are poured into a special tank (hopper), after which it enters the crushing chamber, where the grinding process itself takes place. Grinding occurs using special knives located in this chamber.

Then, the raw materials are sifted through a sieve of a certain diameter (usually there are several of them in a set). It is the diameter of this sieve that will determine the fraction, i.e. degree of grinding of grain or other crops.

By the way, depending on the characteristics of a particular grain crusher, it can process a wide variety of raw materials:

rye;
barley;
legumes;
corn;
cake;
husk, etc.

Some units are equipped with a special disc grater that allows you to grind various root vegetables, fruits and herbs.

How to make it yourself from a washing machine

Advantage this method is that when you independently convert a washing machine into a grain crusher, no need to resort to welding and turning.

Necessary materials

In order to do homemade unit, we will need the following tools and materials:

in fact, the washing machine itself (any with vertical loading, for example, SMR-1.5);
additional electric motor;
drill and drill bits (from 3 to 16 mm);
chisel and hammer;
various keys;
bolts and nuts (M4, M6 and M8).

Also to us you will need a couple of steel plates(32x5x0.15cm and 42x5x0.15cm), which can be cut from a two-handed saw or other piece of metal.

In addition, we will need additional consumables:

metal corner (3×3 cm);
M8 swivel bolts with wing nuts - three pieces;
3-liter tin paint cans - three pieces;
“frog” type locks – three pieces.

The washing machine comes with numerous bolts and nuts, which will also be useful to us later.

Check out the prices for household grain crushers and feed grinders.

Drawing and design conditions of the DCU

It is hardly advisable to give specific dimensions of certain working units of a homemade grain crusher. The fact is that a particular person may have a completely different model of washing machine, which has its own individual parameters and structure.

In this case, the most the very understanding of the conditional construction is important, as well as the operating principle of the entire device.

A do-it-yourself grain crusher from a washing machine and its drawings are quite conventional, based on the example of a specific model. However, by looking at them, you can understand the approximate course further work and the structure of the main components:

Scheme of a homemade grain grinder

Let's look at the example of a washing machine. Oka, which we will convert into a grain crusher. We don't have to disassemble it; we just need to unscrew the plastic part of the activator from the device. We will need the rest of the structure later.

Find out what the Doyushka milking machine is.

In place of the unscrewed activator there will be an additional engine, as well as cutting elements - knives, which must be made double-edged.

Procedure

So, let's get started using the following procedure:

We install the knives made in advance on a pulley whose thickness is 60 mm. For these purposes, we need a flange that would secure the knives when placed on a pulley.
Then you need to equip a special funnel through which the processed raw materials would exit. In the design of these washing machines, the drain is located, which is very useful in our case. It is the drain that we will convert for these purposes.
With the help of a chisel we need expand drain diameter so that it is approximately 150 mm.
We insert the pipe into the resulting hole, and then take it out to the side. That's it, the grain outlet is ready.
Then we need to install the grille at the required angle. This is a rather difficult stage of work, so you need to strictly follow the instructions.
We determine the radius of rotation of the cutting elements, after which we make a notch at the maximum point.
We make a small indent from the serif, and then draw a line. This is where our grid will be located.
We cut the grate so that it fits from one wall of the bunker to the other. We fix it in the structure.
We remind you that we we do not use welding method in our work. Therefore, if there are any gaps in the structure, we cover them with automotive sealant.

In principle, the work process has come to an end. Now comes an equally important stage - the first launch of the device and testing it for normal operation. On the washing machine panel, select the fastest activator rotation mode, and then start the device. Installing knives on the pulley

Motor protection

It is worth noting that the electric motor located at the top of the structure will work in a fairly aggressive environment(dust from grain, small particles, etc.). To avoid this, we cut out tin can protective casing, which is bolted in close proximity to the engine.

By the way, in the place where the drain used to be located, i.e. in the grain outlet area, you need to place a sufficiently capacious container. Processed raw materials will go there.

If you are involved in livestock farming and have cows, we recommend that you familiarize yourself with.

Conclusion

Making your own grain crusher by remaking an old washing machine seems quite a good way to save money on the purchase of ready-made grain crushers.

It is noteworthy that the design of the washing machine itself almost completely meets all the requirements that are typical for grain grinders.

True, some minor additions and improvements will be needed, but they are quite simple and intuitive.

In fact, from old unnecessary junk that is just lying around as trash in the garage, we get a fairly efficient device that allows us to make feed for livestock.

It will be a better and more productive option.
