Description

The purpose of the DKR crusher is to grind a wide variety of grain crops, as well as meal, cake, husks and other types of feed.
Due to the decks, it can also crush coarse and abrasive materials. The device is used at agricultural enterprises and factories for the production of premixes and mixed feed. Due to the possibility of pneumatic unloading (loading) of raw materials, the use of mechanical conveyors is not required. The grain crusher can be built into complexes and lines for preparing compound feed on farms.

The material to be crushed from the hopper, pile or trailer is absorbed by the ejector and then sent to the separator using a flexible suction pipe (the separator has a magnet installed to separate metal impurities, as well as a compartment for removing asphalt and granules). After this, the material is sent to the crushing chamber. Here the grain is crushed under the influence of hammers that rotate inside the crushing chamber. The material then passes through a sieve and, under the action of the rotor, is thrown into the precipitator. Then the product enters the ventilation chamber, and through the pipe and pressure pipeline is sent to the feed mixer or storage bin.

Due to the design features of the DKR crushers, they have quite high productivity. The device is easy to install and easy to maintain. Due to the fact that the sieve in the crusher is replaced by a deck, its resource increases five times. Special modifications of the DKR crusher are intended for crushing straw, chaff and hay.

Technical characteristics and prices of popular models

To make the choice a little easier, it would be reasonable to consider the most popular grain crushers used in various farms. There is no rating as such, we will simply rely on which units are purchased most often.

DKR grain crushers produced at Doza-Agro LLC are distinguished by a rich model range.

The units can be used separately or form a whole complex of grain crushing devices. At the same time, loading of raw materials is carried out automatically, using a powerful air flow.

In such devices you can grind a wide variety of materials - grain, legumes, soybeans, barley, corn, etc. There is also a special category of models that are capable of chopping husks, straw and hay. Let's look at the technical characteristics of the main models:

1000 kg. h.

Models whose performance indicators are 1000 kilograms per hour or more deserve special mention. Such grain crushers are used mainly in large farms where there is a very large number of livestock.

Grain crushers for farms with a capacity of 1000 kg/h are presented on the market in several models, which we will talk about.

To ensure that the equipment does not fail at the right time, we will look for the most popular spare parts for snow removal equipment. Here's all about the necessary snow blower parts.

A quarry excavator is a large earth-moving equipment equipped with a bowl-shaped container with teeth. A quarry excavator is truly a miner of value from the earth.

Special equipment is often required for all kinds of work in the agricultural and construction sectors. Here is an article about the T-130 universal bulldozer.

MDK 1000 belongs to hammer grain crushers. With its help you can grind not only grain crops and corn, but also wood and straw. The design of this unit is such that it can process even wet raw materials, including wood chips.

In general, when choosing this or that grain crusher, you need to pay attention to some points that are decisive. Here are some of them:

• duration of continuous operation of the unit;
• performance indicators;
• the volume of material that the unit is capable of processing;
• faction, i.e. degree of grinding of raw materials;
• dimensions;
• power consumption indicators;
• availability of additional functions, etc.

Only by taking into account all these points can you make the right choice of the required device. Naturally, you also need to take into account the size of the farm itself, the number of livestock, etc.

Device Features

Large farms require a large number of cattle, as well as many pigs and chickens. Naturally, all of them must be regularly and properly fed with special feeds that have a beneficial effect on the life of the animals.

Of course, you can buy ready-made feed and feed them, but their cost is quite high, which increases costs many times over, given the fact that you will have to purchase a lot of feed.

In such cases, the best way out of the situation is to purchase a grain crusher, as well as raw materials, i.e. grain, corn and other crops.

Thanks to this, it is possible to significantly reduce the cost of feeding livestock, which is extremely important for rural areas.

Grain crushers Bumblebee, Bison, Khryusha, Cyclone, Kolos, for farms and households, have good power indicators. At the moment, there are two main types of industrial grain crushers used in large farms:

• Rotary grain crushers. Such devices are quite massive installations, the design of which contains a shaft with cutting elements attached to it. The degree of grinding can be adjusted by changing the rotation speed of the cutting elements.

For more information about the operation of a rotary grain crusher, watch the video:

• Hammer type grain crushers. The design of such devices uses a hammer-type drum, as well as a sieve and deck. Grain crops or other raw materials located in the drum are subject to significant force.

• The degree of grinding can be adjusted by changing the removable sieve (several types with different cell diameters are included).

Compared to rotary units, hammer grain crushers have better grinding quality, which makes them more preferable. However, they have a fairly slow operating speed, which, in principle, is not critical.
