The fact that domestic animals and birds better assimilate ground grain was known to our distant ancestors. They spent a lot of effort and money to grind the feed. Nowadays, this task is easily solved with the help of special devices - grain grinders. Modern manufacturers offer a wide variety of models for industrial and domestic needs, they allow you to grind cereals, legumes, as well as oil plants and root crops.

Peculiarities

Grain grinders are used to grind different types of grain and mix it for maximum assimilation by animals. It is known that certain species of birds, as well as young livestock, are unable to feed on whole grain, so they have to grind it first . The grinder is designed for grinding a wide variety of grain crops - wheat, rye, oats, barley and corn. It is used to process hay, beets, potatoes and sunflower meal, thus making it possible to prepare high quality feed.

The grain grinder consists of several main units, their smooth operation guarantees the functionality of all equipment. Regardless of the factory features, the size of the plant and its operational characteristics, any crusher includes several units.

  • Support frame - vibration-resistant steel construction. It holds the entire main power unit, as well as other factory blocks.
  • The motor is the basis of the installation . It is the engine that generates the force required to crush solid grains and other plant waste. Manufacturers offer models with an engine power of 1.5 kW or more, the more powerful the crusher, the more grain it will grind. However, it should be borne in mind that with an increase in power characteristics, the consumption of electricity, which will be needed for the operation of the equipment, increases many times.
  • Power unit cover - creates effective protection for the user from burns and injury to the skin. In addition, it prevents crop residues from entering the motor.
  • Bunker - a reservoir where raw materials are poured for subsequent processing.
  • Knives - cutting bases, mounted on the shaft of the power unit. This element is responsible for crushing grain and other plant products.

  • Reflector - installed at the bottom of the camera.
  • Sieve - it is necessary for sifting the ground grain.

The mechanism of operation of a grain crusher is as follows:

  • the operator pours grain into a special metal container;
  • after activating the "Start" button, the engine starts working;
  • simultaneously with the movement of the shaft of the power unit, the cutting surfaces are brought into operation;
  • in the process of a circular movement, the functional organs perform uniform grinding of all plant products poured into the bunker;
  • the processed grain goes through a sieve into a previously prepared container.

The grain crusher operates in a cyclic mode, that is, the grinding stroke is repeated with each stroke of the motor.

The grain crusher has its own advantages and disadvantages. The pluses of installations include a number of properties:

  • high performance;
  • feed cutters are easy to use;
  • high quality and durability of equipment;
  • low price for components and consumables;
  • maintainability, the ability to use spare parts from other models;
  • compactness, if necessary, the unit can be easily moved from one place to another.

In addition, due to the simplicity of the internal structure, any repair work, if necessary, can be performed independently without contacting specialists.

Among the disadvantages is the lack of a container where the finished product will be collected. Some models also do not provide electrical protection, such devices may be damaged by voltage surges.

Views

There are household and industrial feed grinders . Industrial plants are distinguished by their large size, increased productivity and the ability to process unrefined coarse grains without compromising functional mechanisms and structural details. In small farms, a household grain crusher is usually used - this is a compact, narrow-profile device, it can grind exclusively refined grain, the presence of husks in which is minimal.

For small farms, this is the best option, which allows you to get an impressive amount of chopped feed without significant expenditure of efforts and funds of their owners.

Both types of shredders are divided into several types depending on the design characteristics.

Molotkovaya

Provides high quality grinding, but at the same time consumes a lot of energy. Designed for crushing forage crops. The required effect is achieved due to the impact of the impact force of the working blocks of the unit.

The design includes a drum and a sieve . In the drum, grains and plant products are crushed and then dropped out through an appropriately sized opening. The parameters of these holes are adjustable, so you can always choose the option that is optimal for the needs of the farm.

Rotary

Rotary grain crushers crush hard grain unevenly, that is, the particles at the exit can have different sizes. However, such installations consume less energy during operation. To neutralize this disadvantage, a mesh is often inserted into the rotary shredder - in this case, it is possible to obtain particles of the optimal size.

Criterias of choice

There are a number of factors to consider when purchasing grain crushers

  • Unit power . The most productive household installations have a power of just below 2 kW - this is the limit for such a unit. Daily power in this case is slightly lower, usually does not exceed 1.5 kW. As for industrial installations, their power reaches 22 kW. These devices process from 800 kg of forage per hour.
  • Rotational speed . This indicator indicates the number of revolutions per minute, the higher this parameter, the better. It is possible to determine the speed of rotation by the parameters of the unit's productivity, that is, by the volume of grain processed in one hour.
  • Unit size and weight . The more compact and lighter the unit is, the more convenient it will be to move it. Usually mini versions are selected for small households and farms. To avoid mistakes when choosing, even before buying, you need to decide for what purposes the unit will be used, and where you will place it (in outbuildings or in a house).
  • Equipment . The kit may include spare parts for the unit, as well as grids that allow you to calibrate the finished product.
  • Hopper capacity . The size of the tank intended for filling the grain affects the effort that a person will spend on servicing the machine. The less capacity, the more often the user will have to fill in a new portion of grain. This means that it will actually be tied to the place of work.
  • Coarseness of grinding . It is selected according to the type of livestock. For example, it is better for cattle to be offered feed in the form of flour, while poultry prefers larger fractions.
