PLANT FOR PREPARATION OF FERTILIZER SOLUTION
One of the main components of effective animal husbandry is a full-fledged balanced feeding, with mandatory inclusion in the diets of mixed feeds, which is based on grain fodder. Production of own compound feeds within livestock enterprises, as well as processing of grain of cereals and legumes into compound feeds for small - scale crop farms is an urgent task that allows to increase the profitability of production. In the preparation of mixed feed, the most energy - intensive operations are grain milling and granulation. The quality of grinding is the basis of the quality of the final product, determined by the granulometric composition of the feed components. Existing grain grinders differ in the design of the main working bodies and in the organization of the grinding process. Most grain feed crushers have working bodies in the form of a hammer rotor and a deck, the degree of crushing in which is set by holes in the sieves. For these crushers, there are several disadvantages-high energy consumption, the formation of a significant amount of pulverized fraction, the need to change the sieves when changing the grinding module, which leads to the suspension of the technological process, and the short service life of the sieves. The disadvantage of grate-free crushers is low productivity when grinding grain feed to a fine grinding module. To eliminate these disadvantages, a grate-free hammer grain crusher with a polyhedral body and reflective plates is designed. It is theoretically proved that the grinding process is jointly affected by the kinetic energy of the active hammer impact on the particle and the kinetic energy of the particle in its passive collision with the reflective plate. It is established that the effective grinding with optimal energy consumption is at the rotor rotation speeds in the range of 50 ... 70 m/s. To implement the possibility of creating a computer program that allows you to determine the optimal circumferential speed of the grain crusher rotor, you can use the algorithm given in the work.
