We have proposed a cutting segment for commercially available feeders; we have also presented the design scheme of the cutting edges and the angle of segment installation on a working body

In this article we consider the analysis of structures of technical means used for the preparation and distribution of animal feed and develop a distributor-chopper, which allows distributing it while milling. The classification is designed for feeders; we also give economic and mathematical model and a constructively technical scheme of a distributor-chopper on its basis

An original design of a piston press, performing material pressing, due to case design tapered piston and the matrix, has been proposed for the first time

We have offered a constructive flow sheet of a root cleaner. Theoretical and experimental studies of roots purification process have been performed. We have also substantiated the main structural and regime pa-rameters of the proposed cleaner

We have presented an analysis of hardware designs for preparation and distribution of animal foods and also developed the economical and the mathematical model of the process of preparation and distribution of food. We have developed a constructive-technological scheme of distribution chopper and a theoretical justification of the parameters of the distribution chopper

The article examines the existing technologies and facilities for the preparation of soybeans for feeding animals, and de-veloped a technological line of preparation of high-protein feed based on soybean. The design of a chopper for soaked soybeans, working on the proposed technology has been pre-sented

The authors have developed classification tools for grinding feeds and the most promising directions in the development of tools for the grinding of forages in reducing energy and metal consumption. We have described chopper stem of feed, which provides high performance and good quality of product. In the article, there is an analysis of existing methods of grinding coarse fodder and their classification. The work presents examples of application of stationary and mobile crushers for crushing of grain and roughage, the technical parameters of the equipment for preparation of feed for feeding

Developed a technological line of preparation of high-protein feed based on soybean. The design chopper soaked soybeans, working on the proposed technology

To increase the productivity of the cattle it is demanded simultaneous distribution of all types of animal feed in the form of balanced feed mixture with a given nutritional value. Balanced feeding of animals can improve their productivity, reduce feed wastage, and include alternative components of feed mixtures in their diets, which have nourishing properties and high digestibility; make and adjust feeding rations. Researches conducted by Russian and foreign scientists, proved the prospects of full feeding of complete feed mixtures, which allow to increase the productivity of animals to 9-30 % and reduce the feed consumption in the calculation of 1 с of milk by 7-8 %. The composition of complete feed mixtures includes sunflower cake, silage, root crops and forage. The process of preparation and distribution of feeds for large horned livestock is the issue of all the necessary components of the feed mixture with a given nutritional value. Saturation of the feed product with extra energy goes during its interaction with the working bodies of technical means for preparation and distribution (TMPD) of different types of food. For preparation and distribution of components of the feed mixture it is necessary to have following facilities, provided with reducing energy intensity and improving the qualitative indicators of processes: for grinding beet fodder and sunflower cake we need disk shredders; for shredding silage and roughage – bearnie and rotor shredders, respectively; for dispensing of beet fodder and sunflower cake – belt conveyor, for dispensing silage and roughage we use disc and drum dispensers, respectively; for mixing sunflower cake - rotary mixers, and for silage, beet fodder and for-age we may use paddle mixers; for distribution of sunflower cake we use rotary feeders, for silage and beet fodder – bin distributors, and for coarse feed we should use conveyor dispensers

The article has a classification of fodder shredders developed on the basis of the analysis of the existing technical means for the preparation of fodders. The constructive technological scheme of the grinder for coarse fodder in a pressed form is proposed. The results of experimental studies in solving the optimization problem-finding the optimal combination of constructive-technological factors of equipment are analyzed, in which a predetermined number of all types of feed will be produced with a higher quality. As optimization criteria, the following were chosen: energy intensity, material grinding time, weighted average particle length
