An innovative solution to the method of preparing compound feeds for farms

The article notes that the preparation of feed directly on farms can significantly reduce the cost of transport operations, and make greater use of cheap local raw materials. To reduce the total installed capacity of feed preparation units and the cost of feed, innovative solutions for the technical support of the feed preparation process are needed. We propose a solution to this issue by using gravitational separation of grain before grinding it in a direct impact crusher, using gravitational separation of grinding products before preparing feed and the versatility of using feed preparation units to obtain various varieties of feed. Application of the developed gravity separator with slotted separation holes makes it possible to efficiently organize working process of gravitational separation of grain mixture, reduce load and improve quality of separation process up to 88-90% without power consumption. The developed design of a direct impact crusher, in which multi-stage grinding of grain is carried out in one working space of the crushing chamber with the removal of grinding products of a given size due to the use of a new effective method of separating grain and feeding it for grinding, allows to obtain a grain grinding module 1,4... 2,0 mm reduce the specific energy consumption by almost 2 times. Application of the developed method and technical solution will make it possible to create high-performance and low-energy fodder preparation units for farms, which will make it possible to obtain a wide range of high-quality feedstuffs with low cost. Developed method of feedstuff production and unit for its implementation differ by low power consumption in comparison with analogues without reduction of quality of produced feedstuff. This is achieved by using a gravity separator and a direct impact crusher with preliminary grain separation.
