Diy grain crusher

Any farmer should take care of his farm. In order for it to be more effective, it is necessary to use means of small-scale mechanization. One such mechanism is the grain crusher. The article will talk about its device and how to make it yourself.

Grain crusher device

This device is designed for grinding grain. As a result of the work of the grain crusher, the grains are cleared of the shell. If this is not done, the stomach of many animals, even a bison, will not be able to digest such grain. After this treatment is done, the food will be better absorbed by the animals, helping to increase their productivity.

In addition, grain is crushed in the grain crusher and passed through a sieve. In addition, you can add the necessary additives to the food for livestock, the chopper will prepare a homogeneous mixture that the livestock on the farm will happily eat.

Types of home grain grinders

Such mechanisms can be classified, depending on the power and productivity:

1. Industrial devices are used on large farms.
2. Small crushers are designed for medium and small farms.

There is also another type of classification. What matters here is which types of feed a particular device is intended for processing:

1. There is a kind of mechanisms that are designed to process root crops. At the same time, they are crushed and mixed with the necessary additives and vitamins.
2. Grain grinders that process silage. They crush the sprouts of malt or grain crops.
3. There are those who are engaged in grain processing.
4. There are devices that have a universal purpose. They can be used to crush various types of feed.

Which is better: hammer or rotary

In practice, two types of crushers are used:

• rotary;
• hammer.

The first of them requires a powerful electric motor to operate. The use of such a grain crusher is universal. It is able to grind all major types of feed:

• grain sprouts;
• roots;
• corn.

The size of the resulting raw material is determined by how fast the motor rotates. Devices of this kind are relatively expensive and are mostly used on large farms.

Grain hammer mill

When talking about a hammer crusher, it must be borne in mind that in such units, the structural arrangement of the grain crusher is more complex than in the previous case.

Such a mechanism should include:

• hammers;
• body;
• a tank into which you need to pour grain;
• power point;
• sieve;
• drum.

After the start of work, the drum begins to rotate, the hammers beat on it from the inside. The grain falls inside the drum and is cracked by hammer blows until it reaches the desired size.

If you compare these two varieties, it is impossible to say for sure which one is better. The hammerhead has a weaker power, but the quality of its work is much higher than that of the rotary one.

You can make your own rotary or hammer grinder yourself.

Grain grinder from a vacuum cleaner

In order to make such a grain crusher with your own hands, you need to take the motor from the vacuum cleaner. Manufacturing will be structurally dependent on which model is taken as a basis.

The principle of this kind of grain crusher will be explained here:

1. First, remove the motor from the old vacuum cleaner. Suppose for definiteness that this household device had a cylindrical, elongated shape.
2. It is necessary to fix the knives on the axis of rotation of the motor. To do this, you can take a steel plate 2 mm wide and long enough to rotate freely inside the case. The motor must be secured; for this, a bar is attached to the top of the cylinder, on which it will be suspended. This will point the motor axis down.
3. It is necessary to make two discs that will be located on the axis of the motor: one above the attachment point of the knives, the other below. They limit the space inside which grain crushing will take place.
4. Discs must be specially treated. In the one below the knives, you need to make a lot of holes. It will function as a sieve.
5. At the edges, the side space should be closed. Except for one hole on the side, through which grain will flow for processing.
6. Now you need to assemble the entire mechanism.

The assembly of this homemade product is done as follows:

1. A large funnel should be attached to the side, into which the grain will be fed for processing. This must be done in such a way that it falls into the side hole between the discs.
2. The cylinder with the motor must be installed vertically on a rack so that a bucket can be placed under it, where the crushed grains will fall.

The scheme of work is as follows. If you pour grain into the funnel and connect the electricity to the motor, the grain will fall into the reservoir between the discs. There, rotating knives will break it until it falls out through the lower disc, which acts as a sieve, into the bucket.

An important feature of this tool is that the motor axis is directed at right angles to the tool.

On this basis, a do-it-yourself grain crusher can be made for a household.

Here's how to make a grain crusher:

1. The base of the structure can be a rectangular piece of thick plywood. A hole is cut in it in the shape of a grinder. It is attached to the base with bolts and metal tape. In this case, the axis of rotation must be pointing down. As knives, you need to take a narrow metal strip of the appropriate length.
2. A hole is made next to the grinder through which grain will flow. In this case, it is important that it is located above the place where the screw rotates.
3. From below you need to attach a sieve to the base. It is made from an old saucepan. In this case, you need to cut off its sides by half the height and make many holes in the bottom (with a nail or a drill bit).
4. Now you need to assemble the grain crusher. To do this, it is installed on a stand, a bucket for processed grain is placed below. For example, you can put a funnel from a large plastic bottle on the hole. Grain will be poured there during work.

Grain grinder from washing machine

The principle of operation of such a mechanism is similar to how a homemade grain crusher based on a vacuum cleaner works. A washing tank is used as a working volume.

The motor is installed so that the pivot point is upward. For crushed grain, a sieve is made in the form of a large number of holes in the side of the tank, made on one side. It is recommended to put a curtain in this place so that the grain does not scatter around the room. Now the hand-made grain crusher from the washing machine is ready.

Corn crusher made of electric motor

If you use a conventional electric motor, then you need to do the following to make such a device:

1. In the same way as described earlier, place the metal knife on the pivot.
2. Place two discs on the axis in front of and after it.
3. Close the lateral space between them, leaving one hole at the top for the flow of grain and at the bottom for pouring out the crushed grain.
4. The bottom hole should be made in the form of a sieve by placing a horizontal metal plate with a lot of holes.
5. The motor is mounted on a horizontal plate. A receiving container is placed under the bottom hole, and a funnel is placed on the top hole in order to pour grain.

Now the do-it-yourself grinder from the grinder is ready to go.

Pros and cons of homemade grain grinders

The advantages of homemade devices are:

1. Cheapness.
2. Ease of manufacture.
3. Good quality of work.

However, they have a number of disadvantages:

1. They are noisy.
2. High probability of breakage.
3. It is not always easy to find the necessary parts and assemblies to complete the work.

Homemade units are beneficial to use where a small amount of grain is required. On large farms, it is more profitable to use powerful commercial grain grinders.
