Design Features

A grain crusher is like a coffee grinder enlarged 10-20 times.

But the difference between one and the other machine lies in some parameters.

Unlike a coffee grinder, a grain crusher grinds grain not into a fine, powder-like powder, but into a coarse-grained substance.
The grain crusher is capable of grinding tens of kilograms of grain in one grinding session.
The more grain you need to grind, the longer the device works. For example, to satisfy the monthly demands of a chicken coop in which, say, 20 chickens lay eggs every day, more than one hundred kilograms of grain will be required. To grind 10 buckets of the same wheat or oats, it will take at least one and a half hours of operation of the unit.

The design of the grain crusher includes a number of components.

Protective housing – made of metals, plastic and/or composite.
A support that is permanently installed in a specific location or removable (portable).
Bracket adjustable with nut and bolt.
The second base has a softener in the form of a rubber “shoe”.
A pair of engines and the same number of sets of pulleys with a diameter of 6 cm. They are equipped with mortise bolts and keys.
Seals that soften vibration from motor shafts.
Knives that chop grain and grass. Both chopped ingredients are the basis of compound feed.
A funnel with a lid into which unground grain is poured. The second funnel allows the crushed raw materials to be poured into a previously prepared container.
Frog type lock.
Removable gratings that allow fractions of different sizes to pass through.
Rubberized wheel.

Each of the above components can be easily and simply installed on an old washing machine.

A grain crusher made from an activator washing machine (or automatic machine) is a device that has the highest performance and capacity compared to similar ones made from other electrical appliances.

Components selected and/or made by hand must be compatible with the overall dimensions of the final device.

No one will install knives that are several times smaller in diameter into the tank for an activator washing machine - the operation of such a device would become extremely ineffective. A volume of grain that would normally be ground in 20 minutes would take an hour or an hour and a half with reduced knives. In other words, the homemade device is physically balanced.

Similar to the device of a coffee grinder, in a grain crusher the knives, combined with the shafts of electric motors, immediately start when the device is connected to the household lighting network. They finely chop small branches, seeds and grass. The crushed raw materials fall on a sieve, which removes husks and small debris. What has been filtered passes into the container through a funnel, collecting in it.

What can it be made from?

Let's look at how to make different components for a grain crusher at home.

The grinding tank is made of thin (0.5-0.8 mm) stainless steel. A metal frame with a valve is fixed next to the base. The outer part of the body is made of a seamless metal pipe with a diameter of 27 cm. The wall thickness of this pipe can reach 6 mm. Inside the same pipe there is a stator, for the manufacture of which a pipe of a slightly smaller diameter was used - for example, 258 mm. In both sections of the pipe, holes are drilled to secure the loading hopper, remove crushed grain, install a grid with the required mesh size, and hangers to secure the shipping hopper. Both pipes are mounted in such a way that they are held in the grooves of the auxiliary flanges located on the side. The latter are connected to each other using several pins. One of the flanges has an internal thread for studs. The second one is drilled in several places. Both flanges also have holes drilled through them to secure the journal bearing housings and are secured to the metal frame using bolts and nuts.

The rotor is assembled on the basis of prefabricated metal pushers and is equipped with washers. If necessary, these pushers are reversed. After assembly, the rotor is checked for imbalance. If beats are still detected, the rotor is balanced immediately - parasitic vibration can shorten the service life of the entire device.
The drive shaft contains feather keys and ball bearing sets. Protective washers for ball bearings are based on the requirements of GOST 4657-82 (size 30x62x16).
The supporting frame with the table is manufactured in a welded version. The starting material is steel angle 35*35*5 mm. The valves are made of thin sheet steel.
Having prepared the necessary materials and workpieces, we begin to assemble the grain crushing device.

Other models

Crusher from washing machine

The principle of operation of the grinder in this case will resemble a coffee grinder. This type is most suitable for crushing corn, because the knives rotating in the drum work best with large and relatively soft grains. The device can be made from any model of washing machine, but the manufacturing principle is the same.

The following steps must be completed:

Install the first motor with the bushing and blades at the bottom of the washing machine tub. There will also be a mesh and an outlet window through which the finished product will flow.
The second motor, also equipped with a bushing and blades, must be secured at the inlet hole near the base. A tin can placed over the knives will act as a barrier against dust and contaminants.
The shafts must be installed at an angle of 25 degrees to each other, because they will rotate in different directions. This angle will ensure maximum performance of the mechanism.
The input funnel for raw materials can be of any size. However, it is advisable to make it large, because a washing machine crusher is very powerful and designed for high productivity. You can regulate the supply of cereals by installing a shutter at the bottom of the funnel.
The container for the finished product should be installed under the grain crusher. It is better to equip the device with a sleeve to prevent fine dust from getting into the air.

As you can see, the main element of such a grinder is the drum of the washing machine, and the main additions - a funnel and a container - are very easy to manufacture.

Homemade mill

A homemade crusher mill at home can be made from a rotor and stator, which will serve as millstones.

Manufacturing instructions:

Install a single-phase electric motor with a power of 1 kW and a voltage of 220 Volts on the box.
The crusher body must have a diameter of 35 centimeters and be made of steel strip. The stator is installed at the bottom, the rotor is installed on the motor shaft. The shaft moves at an angular speed of 3000 revolutions per minute.
The hopper should be attached to the top of the housing using bolts. It should have a cone shape to make it convenient to pour the raw materials. It is advisable to equip the funnel with a shutter. The lower part of the apparatus must be equipped with a window for exiting the finished product. If possible, you need to equip the outlet with a sleeve.
You can make a stator like this: take a steel plate 5 cm wide, give it the shape of a cylinder and place it in a container for subsequent pouring. The bottom of the cylinder should be 4 mm thick, and the walls should be covered with a layer of aluminum. To increase the rigidity of the stator, you need to weld 2x2x5 angles inside the bowl.
Drill a hole in the center for the shaft. Make a rotor blank - cut a circle from sheet steel with a diameter of 32 cm, measure 2 cm from the edge and draw a circle.
Divide the circle into 32 equal parts, drill holes in each, and cut strips from them with a hacksaw to the edge of the disk. Bend the resulting petals. Weld a bushing in the center of the rotor with a diameter of 3 and a height of 5 centimeters, respectively.

For proper operation, you must first install the stator on the shaft, and only then install the rotor on the gasket.

From an old vacuum cleaner

In this case, a motor from an old, but still working properly vacuum cleaner will come in handy.

Step-by-step instructions for making such a grain crusher:

The base of the device must be made from a square sheet of plywood with an edge length of 30 cm. The motor from the vacuum cleaner must be attached to the plywood so that it protrudes 4 cm down.
The knife should be made of a steel plate with dimensions HxLxW equal to 1.5x20x1.5 cm. The leading edges of the knife are sharpened towards the axis of rotation. You need to drill a hole in the middle of the knife to fit it onto the shaft.
The working chamber must be made of a plate 6 cm wide and 70+1 cm long (taking into account the allowance). The leaf must be wrapped in a ring. Attach three wooden rods at equal distances to secure the grain crusher at the bottom of the chamber.

The holes for the crusher mesh vary depending on the purpose of the crusher. The diameter of the cells for flour should be very small, for mixed feed - several times larger. The funnel for feeding raw materials must be equipped with a shutter; to receive the finished product, a sleeve or a regular container should be installed if the feed size is large.

Schemes and drawings

The grain crusher from the washing machine contains the following components:

grain bin;
frame;
rotor;
shaft;
unloading hopper;
pulley (the requirements of paragraph 40 of GOST 20889-88 are met);
V-belt;
electric motor;
frame with table;
loading and unloading valves (valves).

Drawings of analogues made on the basis of a motor from a vacuum cleaner, electric drive of an angle grinder, drive and mechanism of a meat grinder differ little from the device made on the basis of a (semi-) automatic washing machine. The principle of operation of the device is no different - which cannot be said about the type of chopping mechanics used.

Master class on making a grain crusher from a washing machine

If you have purchased a new automatic washing machine, do not rush to throw away the old type of device. It will definitely make a high-quality and productive grain crusher. You just need to develop a detailed drawing and purchase some elements.

What you need for work: prepare the essentials

The list of materials and tools will depend on the chosen scheme. Most often, only the motor from the washing machine is used. However, if desired, you can also use a tank.

You will also need:

rolled metal: plates, pipe sections;
fasteners;
sealant.

Device diagram

In terms of its design and operating principle, a grain crusher is similar to a coffee grinder. During the manufacturing process, the main attention should be paid to the knives and the hopper for receiving the finished product.

Preparation of prefabricated elements

We begin work by preparing the grain bin. We increase the diameter of the drain hole to 12 - 15 cm to ensure sufficient performance of the device. From pipe sections we make pipes of the required size and configuration for discharging crushed grain.
We cut three knives from durable steel. These should be plates 20 cm long and 1.5 - 2 mm thick. To make the device last longer, you can use a hand saw to make these elements. We drill a mounting hole in the middle of the prepared plates. We sharpen the parallel sides.
We make a filtration grid that will not allow whole grains to leave the container. Its diameter should be slightly larger than the diameter of the manufactured pipe. The holes in the filtration grid must ensure the unhindered passage of crushed grain.

Attention! The diameter of the filter grid holes should be 3 – 4 mm.

We are preparing a container for crushed grain, or we are thinking about a way to secure the bag to the outlet pipe. To prevent the formation of excessive dust during operation of the device, the receiving hopper must be sealed against the outlet pipe.

Assembly of the structure

We assemble as follows:

We install a discharge pipe into the expanded opening of the tank, ensuring sufficient tightness of the connection.
We install the knives on the motor shaft. To avoid overlapping of the blades during operation, be sure to tighten the clamping nut after each plate.
We attach a filtration grid in front of the outlet pipe. It should be located at an angle of 15 - 200 to the horizontal. Considering that the bottom of the washing machine tank is inclined to ensure complete drainage of water, there should be a right angle between the base and the installed plate. To fasten the plate we use bolts.
We coat the joint with sealant to eliminate the presence of gaps and cracks through which whole grain could mix with crushed grain;
Let's start the device. Let's check its functionality.
If you don’t have a solid washing machine, but you still have a working engine, you can also use it to make a grain crusher with your own hands.

Kruporushka from angle grinder

Making a grain crusher is very simple - even a beginner can handle the task. In this case, a homemade grain crusher will not require expensive components during assembly.

Tools and materials

It is necessary to prepare everything you need in advance so as not to be distracted while working with electrical equipment.

To make a grain crusher you will need the following materials:

angle grinder (angle grinder);
sheet of metal - preferably stainless or alloy steel;
fasteners;
drill;
roulette.

As you can see, nothing expensive is required.

Preparation of material

Stages:

First you need to cut out the two side covers of the case.
Drill a hole in one of the covers equal to the diameter of the grinder shaft.
Drill holes for the mounting washers, then four holes for the coupling bolts.
Cut a strip of metal. One part will be used to make a sieve, in which cells of the same diameter are shot through according to a certain pattern, chosen independently.
Then the sieve should be bent in a semicircle.
The second strip is used to make end caps.
From the remains of the leaf you can make a knife for grinding cereals.
An incision is made along the edges of the second strip, and a hole is drilled in the middle.

Welding

First you need to weld the end caps, then the sieve. A strip is attached to the top of the machine at an angle of 15-20 degrees, which will prevent the grain from flying back out of the machine.

It is very important to select the thickness of the metal in advance - at least four millimeters, so that the housing and the grain guard are strong enough. Grains are hard abrasive particles that can ruin even expensive and massive industrial equipment within a few years.

Assembly

Step-by-step instruction:

It is necessary to screw the washer and install the angle grinder.
A knife should be installed on its shaft and securely secured with a nut.
Then install the side cover. It can be attached with wing nuts for quick and easy removal and reattachment.
A funnel for feeding raw materials can be made from a plastic bottle.
The final touch is to attach a bag or sleeve to the bottom of the apparatus for collecting the finished feed.

Making your own grain crusher from a vacuum cleaner

If you don't have a washing machine, look for a vacuum cleaner. It can be used in whole or in part. It all depends on which design seems more attractive to you and what skills you have. We invite you to get acquainted with a possible implementation option.

We prepare everything necessary for work

To make a grain crusher from an old vacuum cleaner, you should prepare:

metalworking and metal-cutting tools;
sandpaper;
drill;
fastening elements;
pipe sections about 15 cm long for making an outlet pipe;
ready-made knives or metal plates for their manufacture;
a lattice with small cells, which is necessary for the manufacture of a sieve intended for sifting grain. If this is not available, you can use a metal sheet in which holes of the required diameter are drilled.

Attention! The above list is approximate.

Device diagram

The design of the device depends on which part is used. Most often, preference is given to options that involve the use of one engine. It is installed on the base, under which there is a container for receiving crushed grain.

Preparation of prefabricated elements

At the preparatory stage:

we make the base using plywood, laminate or rolled metal;
disassemble the vacuum cleaner to remove the engine;
drill a hole in the base. Its diameter must correspond to the diameter of the motor shaft;
If there are no ready-made knives, we make them from metal plates. With a thickness of about 1.5 mm, their length should not exceed 20 cm;
If there is no ready-made sieve, we make it from a metal sheet.

Assembly of the structure

The process of assembling a grain crusher from a vacuum cleaner includes a number of stages, each of which deserves special attention:

Using a nut, fix the knife on the motor shaft;
install a sieve;
We place a container under the sieve into which the crushed grain will flow.

Attention! Installing a tin box for loading grain will simplify the crushing process.

Assembling a grain crusher

The drum is cut on a lathe: its height should not be more than seven centimeters. The drum will serve as the base. On the same machine, an internal recess with a diameter of 28 cm, with a wall height of 3 mm, is machined. Next, a third of the drum is cut off, and a sieve is installed inside. For greater strength and better fastening of the sieve, steel arcs can be welded to the outer edge of the drum. The coulter disc is adjusted to the size of the drum and is also welded.

To ensure good performance, several holes with a diameter of about 8 mm are drilled in the hub. This will allow air to enter the working chamber.

The manufacture of a hammer drum begins by welding plastic to the top of a steel shaft. A small hole is made at the end of the shaft into which a puller bolt is screwed. They also drill several holes in the base of the drum for rivets. The diameter should be no more than one centimeter. The gap between the hammers is adjusted using washers. The hammers are placed parallel to increase the intensity of crushing.

When the hammer drum rotates clockwise, the grain is crushed faster and the fraction is larger. When rotating in the opposite direction, the grinder produces a finer grind.

From the Bulgarian

A characteristic property of a manual electric grinder is the axis located perpendicular to the cutting disc. To make a grain crusher from an angle grinder (grinder), do the following.

Mark and cut a rectangular piece from thick (1 cm or more) plywood.
Cut a round hole in the cut piece of plywood - in the shape of the main structure in which the cutting disc rotated.
Secure the plywood with the bolts and metal bracket included in the kit. The axis of rotation should be directed downwards.
Make a cutter from a steel strip of suitable length, width and thickness. As in the previous case, the knives must be carefully sharpened and centered. Insufficient centering can eventually break the angle grinder gearbox.
Not far from the angle grinder mounted in the tank for crushing grain, make a hole and provide it with a funnel. Through it, uncrushed raw materials are poured into the grain crusher. The funnel with a hole is placed not under the grinder drive, but above it.
Below the drive, mount a sieve made from a used pan. It is drilled using a small drill (about 0.7-1 mm).

Assemble the grain crusher. Place it on a pallet or box. Under the lower funnel, where the crushed raw materials are poured, place, for example, a bucket. The funnel can be made from the cut off top of a plastic food bottle - the diameter of the neck is enough for the poured grain to easily and quickly pass into the grain crusher.

From a meat grinder

To make sure that the meat grinder will grind the grain, you can use resins, for example, hazelnuts or walnuts in shelled form. There is no need to make a knife that performs the functions of a cutter “from scratch” - it is already included in the kit. For the small fraction of grain, you must use the smallest standard sieve, also included in the delivery set.

In order for the grain to be milled continuously, it is necessary to install a large funnel above the grinding mechanics, for example, from a 19-liter bottle with the bottom cut off.

A hole is made in the lid of a diameter at which the poured grain will not pass through the neck faster than it is passed in crushed form through the crusher of the meat grinder. In principle, the meat grinder does not need to be modified in any way. The grain should not be too hard - not all meat grinders can handle durum wheat equally effectively. If you cannot use a meat grinder as a grain crusher, use a coffee grinder.

How to make a crusher mill with your own hands

Making a grain crusher with your own hands is not that difficult. To do this, you need to have on hand a motor from an old household appliance, for example, a vacuum cleaner or washing machine.

In addition, you must have some locksmith skills. By the way, when assembling such equipment with your own hands, you need to remember the safety rules. Since all engines operate on electricity, it is necessary to take all measures to reduce the traumatic risk of the assembled product.

We must not forget that fast-rotating parts are used as a working body, which can cause injury to the person working on it.

Structure of a grain crusher, design features of the machine

Manufacturers put a variety of crushers on the market, with different characteristics, productivity, etc. Most of this equipment is easy to maintain and does not take up much space. As noted above, in practice crushers are used that use rotary or hammer principles in their operation.

Rotary machines have a drum with knives. In hammer mills, hammers are used as a working tool, which are loaded inside the drum.

By the way, there is equipment that uses compressed air as an energy source. The processed raw material moves inside the drum along with air. As a result of this, the quality of the resulting product increases dramatically. In addition, in this, and in many other designs, magnets are used that select metal particles that get into the mixture.

Do-it-yourself hammer crusher for grain – Special equipment

The grain crusher is a universal unit for grinding small and large grain crops for feeding pets.

Using a grain crusher, you can significantly save energy and time, and the feed that is processed with its help can be mixed with additives that improve the diet of animals.

In our article we will look at how to make a grain crusher with your own hands for use in the household. The main parameters of these devices will also be discussed.

Design features of the grain crusher

Before starting to review the device, it is necessary to thoroughly understand the purposes for which this mechanism is needed.

With the help of a grain crusher, feed crops are crushed, making them attractive to animals.

After all, small foods will be much better absorbed by your pets, and this will contribute to faster weight gain, and the animal also receives all the necessary vitamins and minerals.

The chopper has a very simple design; it is based on a durable body, which is also a chamber for grain.

The design also contains cutting components that are driven by an electric motor. An electric motor is usually used as it is much easier to install on the structure.

But to make it more convenient to use the grain crusher, you can equip it with handles. Some models have removable wheels.

Types of grain crushers for home use

Any household grain crushers are small in size and simple. But despite this, all models have quite high performance.

Therefore, the device allows you to process large batches of grain in a short period of time.

If we divide according to the principle of functioning, we can distinguish the following:

Impact crushers. Such units have working chambers made of durable metals. Therefore, the machine’s reliability is very high. The elements that are crushed hit the walls of the bunker, with the help of this the grain is crushed. Please note that the crushing components hit the walls until the grain is crushed.
Disc machines - in such designs, the crushing knives are fixed on the shaft using disks.
Hammer machines - in the design, the grinding elements are mounted on a rotor, which rotates in the receiving hopper.
Roller crushers - they can both crush and grind grains. The main element in the design is grooved rollers. With their help, it is possible to efficiently process exclusively wet grain. Therefore, if it is dry, it must be moistened in water in advance.

Classification by drive type

Below we will look at how to make a simple grain crusher from a grinder with your own hands.

In general, crushers that are used in everyday life can be divided according to the type of drive:

Manual crushers are the simplest devices; for this device to work, it is necessary to use force and also spend a lot of time. Using such units, you can grind grain into a coarse product. It is suitable exclusively for adult animals, in particular bulls or cows.
Pneumatic devices are used to process corn and other small grains. Using such a device, you can very quickly grind food into small fractions, so that you can subsequently mix it into food for feeding small animals and poultry. Features high performance. You can make such a home grain crusher with your own hands quite quickly, with minimal investment.
Electric grain crushers are also distinguished by their simple design and fairly high productivity. The dimensions of the device are not very large; it can be used both at home and on farms.

Rotary or hammer grain crusher: which is better?

Now let’s talk about how to make a grain crusher with your own hands and what type of design is best to choose.

If you have a question about which crusher is better, you need to carefully study the design differences between these units. The rotary chopper works by moving the cutting blade.

With its help, the mass fed into the receiving hopper is crushed.

Hammer units crush raw materials using hammers mounted on a solid base.

How to choose a grain crusher: expert advice

Choosing the right model

How should you choose a crusher that will meet all consumer requirements? To do this, you need to know the answers to some questions:

Performance. A high grinding speed ensures high productivity in obtaining finished products, and accordingly, the use of such an installation will be highly efficient. Such installations can be considered the optimal solution for large farms. For home work, an installation with a low or medium processing speed of raw materials is sufficient.
Price. The equipment must not only ensure high quality of the resulting product, but also generate certain income to recoup the investments made in this equipment.
Grinding degree. The device must be selected based on the type of livestock and poultry the produced feed will be intended for.
Drive station power. The greater the power of the installed power plant, the greater the productivity of the installation. It must be taken into account that the higher the engine power, the higher the energy costs.
The company is a manufacturer. Undoubtedly, there are world-famous companies that produce shredders, but you need to think three times about how quickly the funds invested in brands will pay off.

When choosing a model, you must be guided by the characteristics specified by the manufacturer.

Crusher balancing process

Most equipment that uses rotating components as a working tool undergoes a balancing procedure. This work can be done either independently or with the help of invited specialists.

When balancing, the following sets of work must be performed:

identifying the causes of vibrations and eliminating them;
monitoring the condition of equipment in terms of vibration;
balancing shafts in existing bearings;

Why is balancing necessary? The answer lies on the surface. The thing is that the presence of excessive vibration leads to failure of the bearing units, and as a result, everything can end very sadly.

What equipment is needed for grain storage

The provision of granaries with technological and engineering equipment depends on the functional purpose of the building. Mechanized conveyors are installed in rooms with sloping floors.

List of equipment that allows you to control the microclimate:

fans providing condensate removal and air supply,
temperature and humidity sensors,
floor ventilation ducts for active ventilation during grain storage,
control center system unit,
ventilation units for supply and exhaust ventilation.

Grain crusher performance

The process of functioning of a rotary chopper involves the movement of the cutting knife. It is needed to crush the masses that should be fed inside the receiving hopper.

The hammer preparation can grind grain efficiently using hammers that are attached to a strong base.

Products obtained using a hammer machine will be considered the most effective. This can be achieved with the help of a high amplitude of movement of the hammers, which are capable of crushing even individual grains of grain.
At the same time, the impact crusher can consume much less electricity and has a high productivity factor.
If the farm has a large number of adult livestock and poultry species, it would be best to buy an impact crusher. But in the case when a farmer breeds smaller poultry and a large number of young livestock for trade, then the optimal choice in this case will be in favor of hammer grinding of grain.
It is imperative to test a device that you have produced yourself. It is worth remembering that the grinder engine requires regular lubrication, otherwise it will quickly break due to abrasion of the main elements in the device.

Product types

The first grain grinders or grain crushers were millstones on which grain was ground manually or with the help of horse traction. Over time, this design was improved and today you can find different types of grain crushers.

Centrifugal

Centrifugal or impact crusher is based on the impact crushing method. The design resembles a centrifuge. The grain enters a rotating plane, is accelerated by centrifugal force and is thrown into a crushing chamber with a special hard lining. The high kinetic energy of particles ensures their destruction upon impact with a stationary wall surface. The pressure in the chamber is created by a fan.

Screw

The screw type grain crusher has crushing screws that ensure grinding. The body is welded, with a groove-lattice bottom. Similar designs are used for crushing coal. They have a large margin of safety and are suitable for processing hard grain crops.

Melnichnaya

Mill or jaw crushers are historically the first type of crusher. The principle of operation is simple: the grain is compressed by two solid plates (cheeks), one of which is fixedly fixed, and the second is installed on a swinging base. Performing reciprocating movements, the swinging and stationary jaws compress and thereby crush the raw materials entering the machine.

The advantages of such crushers:

simplicity of design and, therefore, manufacturing and repair;
the ability to adjust the throughput channel to select the required grain size obtained at the output.

The disadvantages include:

rapid wear of such mechanisms due to abrasion of the pressing elements (cheeks);
uneven shape of processed grains.

Rolling

Another option that has stood the test of time is the roller mill, which can be supplied as an automatic or manual model. The main mechanism of the design is a movable shaft. Its function is to redirect the flow of grain into a small gap between itself and the stationary part of the structure. This ensures high-quality and fast grain grinding.

You can make a cereal yourself

Depending on the design, the grain crusher can be:

two-roller - has lower productivity and a very simple design;
three-roller - equipped with an additional shaft and allows for better grinding of raw materials.

This type of crushers is characterized by high quality processing and an affordable price. They quickly pay for themselves due to increased productivity and quality of the finished product.

Recommendations

To ensure that the shredder's performance is high enough, follow the advice of experts.

Insulate the motor using an additional casing made from, for example, a large tin can. The fact is that the motor gets into a dusty environment - this dust is formed when grinding dry grain. The engine may become clogged with deposits, and its operation will slow down - a noticeable part of its useful power will be lost.
Do not use the grain crusher at maximum speed, trying to grind tons of grain in one go. A large farm with large numbers of farm animals will require two or more grain crushers. It is better not to skimp on equipment so that it does not break down after a few days, but works for a number of years.
Use grain collection containers with as large a capacity as possible.
Clean and lubricate the mechanics every three months or six months. Regular maintenance - and scheduled replacement - require bearings, without which no electric motor would work.
The listed measures will allow the user to process large volumes of grain without investing extra in repairs and without stopping urgent work.

Design of the Shmel grain crusher

The Shmel brand crusher is distinguished by the simplicity of its factory design, which makes it as convenient as possible in operation and routine maintenance. The unit is equipped with an electric motor operating from a mains voltage of 380 V. The motor power is 11 kW and the shaft rotation speed is 3000 rpm. Thanks to its increased endurance, the Shmel grain crusher produces 3 tons of fine-grained feed per hour of operation. The volume of waste depends on the density of the raw material and the speed of its supply for processing.

The Shmel grinder is equipped with a special sleeve with an automatic suction function. Immediately behind it there are 2 separate chambers. In the first, the primary processing of grain is performed - cleaning from husks and separating from foreign impurities. Next, the raw material enters the second chamber, where it is crushed to fractions set by the operator.

After grinding, the finished feed goes into the second sleeve, from where it can be packed into separate bags or the body of a car. As soon as the Bumblebee grain crusher crushes the amount of grain specified by the operator, it automatically stops working.

During operation, the Bumblebee grain crusher does not emit grain particles or dust. For this purpose, the design of the model includes a special filter that prevents debris from leaking out.

To extend the service life of the Shmel grain crusher, the manufacturer equipped it with a magnetic catcher. It attracts wire or nails that may fall into the processing chambers along with the raw materials.
