All about grain crushers

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.

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 the grain crusher is as follows:

• the operator pours grain into a special metal container;

• after activating the "Start" button, the engine starts to work;

• simultaneously with the movement of the shaft of the power unit, the cutting surfaces are brought into operation;

• in the process of 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 has its 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.

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.

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.

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

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 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.

In the design of this type of crusher, discs are provided that work in the manner of millstones. Cutting surfaces are fixed on them, the distance between them can be adjusted. Thus, the device allows you to set the parameters of the finished chopped feed.

The principle of operation of roller grain crushers consists in the movements of corrugated elements that crush the raw materials.

Mechanical hand models are considered the most convenient to use and maintain. They allow you to quickly grind root crops and grains to coarse grinding. Typically, this feed is used in the diet of adult cattle.

Such devices are characterized by high performance combined with simple design. They have compact dimensions, therefore they are widely used in small backyards and farms.

Pneumatic crushers can be hammer or rotary. Both are powered by air supply, thus significantly saving energy costs and minimizing operator effort.

Among the owners of small farms, models of electric rotary grain crushers are most in demand. Manufacturers equip them with both standard blades and turbine milling blades. The second option gives the maximum speed and fine fraction of grinding, regardless of the primary parameters of the grain and its state.

We offer an overview of the most popular models of grain grinders.

If cattle are raised in the farmstead, then a productive crusher for hard grain will be needed to make feed. This condition is met by the Bizon unit. This rotary device works efficiently even with solid particles. The power of the unit is 1.75 kW, the movement parameter is 16,000 rpm, thanks to this, the unit threshes not only rye, millet and oats, but also sunflower meal and other oilseeds. Productivity is 400 kg / h, which is quite a high level. At the same time, the unit has miniature dimensions, weighs only 7.5 kg, so there are usually no difficulties with its transportation.

The "Don" crusher allows making useful feed for poultry and animals. It crushes not only cereals, but also beans and roots. Grinding of products of different density is carried out thanks to a sharp blade driven by a 1.8 kW asynchronous motor. The plant productivity corresponds to 180 kg / h.

The design provides for three interchangeable sieves, due to which the operator can select the appropriate fraction of the crushing of the plant product. Users note the good build quality, which leads to an impressive service life of the equipment. The advantages of the model also include the rigidity of the structure, reliable wiring and good coloring. The installation does not give vibration and is characterized by unpretentious use. The only drawback is called a significant starting current, this is due to the presence of a capacitor.

The "Farmer" manual grain crushing machine is specially designed taking into account the wishes of domestic agricultural producers. It is equipped with a 1.3 kW motor, this working resource allows you to grind up to 400 kg of workpieces per hour. The design provides for the option of adjusting the size of the fraction. The package includes a sieve with a hole size of 5 mm, it is possible to use replaceable sieves with a perforation of 4 or 6 mm.

Users note that such a grain grinder can be operated for up to 7 years. However, like most others, the products are not without their shortcomings. First of all, this is the laboriousness of container installation, impractical coating and a noticeable level of noise during operation. Nevertheless, crushing is carried out promptly and efficiently, even with frequent use, the risk of breakdowns is minimized.

In order to always have freshly prepared feed at your disposal, you can purchase the "Three Little Pigs" grain grinder, which is a productive equipment. Despite the fact that no more than 5 kg of grain can be poured into the receiver, the device processes up to 300 kg of product for each hour of operation. Such a high performance is due to the power of the 1.9 kW electric motor. The set includes a replacement sieve and cutting bases. The device is lightweight, only 6.5 kg, so if necessary, even women and teenagers can cope with its movement.

User opinions on this grain crusher vary. Some farm animal owners call it the optimal model for day-to-day feed formulation. Others are not satisfied with the capacity of the bunker, because of this they have to constantly replenish it. No one has any complaints about the quality of the grinding itself. The only negative is the noise during operation.

Miniature grain crusher of Russian production is intended for domestic use. Productivity is quite high: the unit grinds up to 350 kg of grain and wet feed per hour.

This crusher has practically no complaints from users. The unit copes effectively with the shredding function. Combines exceptional performance and affordable price.

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. The daily power in this case is slightly lower, usually not exceeding 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 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.

In conclusion, we will give some recommendations for the operation of the equipment. It is important to follow them so that the device will serve you for a long time.

Be sure to turn off the power to the crusher after finishing work.

Before operation, turn on the engine with an empty hopper, this will allow it to pick up speed. If this is not done, the motor will restart. The idle time is usually indicated in the user manual.
