Abstract: The task of increasing the nutritional value of feeding diets of farm animals is currently relevant. In addition, it is necessary to improve or develop new technologies and equipment to improve the possibility of long-term storage of feed without losing its high-quality and durable characteristics. Granulation of feed allows you to store the product for a long time, to dose it when distributing to livestock, to balance diets for different age groups. In the technology of preparation of granular feed, an important place is occupied by separation of granules or fractionation, that is, division into classes (granules of a certain shape and size), while non-conditioned material is sorted (clumped granules, broken or incorrectly cut with a granulator knife, dust, small fragments). For the effective operation of the granule separator by class, it is necessary to justify the technological process and the structural and kinematic parameters of the working bodies. The movement of granules on the surface of the sieves is carried out by vibration and gravity, due to the inclination of the sieve to the horizon, the efficiency of sieving granules will depend on the shape and size of the sieve holes. The choice of separation technology, the order of operations, loading, separation, cooling, delivery to the animal feeding site will determine the productivity of the granular feed line, its quality and, consequently, will eventually increase the productivity of the livestock as a whole. Improving the structural and kinematic parameters of the granule separator will make it possible to reduce specific energy consumption. The article discusses the directions of development of the technology of granulating animal feed, using as one of the aggregates of the line separator-separator granules and presents measures to improve its operation.

Keywords: granule, separation, separation, fractionation, vibrating screen, sieve.

Abstract: The production of feed additives is a necessary element of the system of raising farm animals, increasing their productivity, health, fertility. In the line of preparation of granular feed, after pressing the product and obtaining granules, their cooling is required to increase the hardness and strength, reduce temperature and humidity. If the pellets meet the requirements, the costs associated with the culling of pellets will decrease due to their resolution, loss of quality and inability to use in the diets of farm animals. There are enough variants of coolers, however, the physico-mechanical properties of pellets make adjustments to the limitations in the possibility of using a particular machine in the general technological process of feed production. In addition, for any efficient production line, the principles of flow and continuity are mandatory, then the performance of one unit is related to the throughput of other equipment. Therefore, the purpose of the article is to review potential means for cooling pellets and substantiate the parameters of the cooler elements, as well as embedding it in the technological process of production of feed pellets.

Keywords: granules, cooling, temperature, moisture, cooler, separation.
