The Quality of Grinding of Grain Feeds Depending on the Construction Parameters and Operating Modes of Vibrating Disc Crusher

Abstract

Full-fledged animal feeding is the basis for the successful functioning and effective development of the livestock production industry and can be ensured only if a sufficient amount of feed is produced, the loss of their nutritional value during their harvesting, storage, and also the correct preparation of feed for feeding is reduced. Grain feeds used at concentrated feed. They contain a large amount of nutrients that are easily absorbed. Their use in the feeding system allows you to balance the rations of animals in terms of energy, protein, amino acids. The compilation and selection of components of feed rations is carried out by technologists depending on the species, age group, morphological and biological indicators of animals and many other factors. At the same time, regardless of the technology and feeding scheme chosen by the specialist, concentrated feed based on wheat, barley, corn and other agricultural crops that have undergone preliminary technological processing remains an indispensable source of nutrients for animals. Moreover, a particularly important indicator that affects the productivity of animals is the quality of grinding concentrated feed. As a result of grinding feed, a significant number of parts are created from a larger surface area, which helps to speed up digestion and increase the absorption of nutrients. Grinding is one of the most energy-intensive operations used in the production of animal feed. Therefore, scientific research is aimed at minimizing the consumption of energy resources by crushers and increasing the grinding process is an urgent task. The article presents the results of experimental studies of the preparation of grain for feeding farm animals using a vibrating disc crusher, which was designed on the basis of the Department of Department of General Technical Disciplines and Labor Protection of the Vinnytsia National Agrarian University and passed preliminary experimental tests, which proved the prospects of its use in the processes of grinding grain raw materials. The choice of the range of design parameters was performed on the basis of assessing the compliance of the degree of grinding of the finished product with zootechnical requirements for the target fraction of the finished product.

Controlling the dynamic characteristics of steel bunker containers for bulk materials

“…Thus, the author's research on this issue was carried out in the early 2000s and allowed for the first time to obtain a spectrum of the natural dynamic characteristics of steel capacity structures. Modern domestic research is rather narrow and fragmentary [1][2][3]. At the same time, modern foreign research on this issue is even more limited [4][5][6].…”
