The issues of implementation of the technological process of preparation of feed components for feeding for cattle are considered. The main factors of complete feeding are: a complete set of essential nutrients, timely and affordable and optimally coordinated in quantitative terms of their entry into the bodies of animals. The process of grinding feed components, to a large extent, depends on their physical and mechanical properties. One of the conditions for preparing the feed mixture is the minimum use of additional machines that perform the operations of grinding, mixing and distribution of the finished feed mixture, because it leads to higher energy and labor costs. These costs are associated with additional loading and unloading operations of feed components. In the study of the processes of grinding feed materials, according to the technology of preparation of feed for feeding, using mobile combined feed preparation units, provided their grinding, loading feed components was carried out in the following sequence: first loaded roughage, then root crops, for storage stands out. However, experiments have shown that roughage, in the process of grinding, act as a shock absorber, mitigating the impact loads on the roots of tubers from the knives, cuttings and walls of the hopper. At the first loading of root tubers the process of crushing was more intensive. Experiments with long-fiber materials and roots, showed that the presence of crushed roots in the hopper, when loading roughage, the duration of grinding of the latter does not affect. To intensify the process of grinding long-fiber materials (straw), experiments were conducted with the addition of feed with a larger bulk density (silage), which was introduced after the destruction of the roll. The results of research have shown that the addition of silage can increase the intensity and degree of grinding of straw, this is due to the compaction of the mass in the active cutting zone. This solution allows you to reduce the technological time of the unit and increase its productivity.
