The paper presents experimental studies to determine the moment of inertia of the moving disk of the grinding device. A method was used to determine the flywheel masses and moment of inertia from the «Vybega» curve. To determine the mechanical characteristics of the grinder, the method of a calibrated collector machine of alternating current was used. The mechanical characteristics of the grinder are obtained depending on the size of the abrasive, the value of the angle of curvature of the grooves and the size of the gap between the working bodies of the device being developed. Regression analysis made it possible to estimate the value of the resistance moment of the grinding device at a given value of the abrasive value and speed.

The most efficient way to prepare the leguminous plants’ seeds for the livestock animal food is making of the protein emulsion. There are a lot of ways of obtaining the protein emulsion. However, process operations provide for the use of large-scale, energy-intensive and expensive machines, which often cannot be afforded by the small enterprises producing more than 50% of animal and poultry products today. This way, it is necessary to develop a universal technology of making the protein emulsion applied in small holdings. The research objective is the development of a waste-free technology of making the protein emulsion for animal food. Proceeding from the patent search for technologies and designs to make a protein emulsion we offered a waste-free technology, which makes it possible to unite a whole number of technological operations (chopping, extraction, a division of suspension into fractions) into one operation through using a new facility, the RF Patent No. 2614777. Theoretical and experimental research of processes of the grain chopping and the soy protein extraction into emulsion was described. The main design and standard parameters of the device developed were substantiated theoretically and experimentally.

The main vector of mechanization and automation of livestock farming at the present stage of technological development of producers is the improvement of resource-saving technologies and technical devices that enables agricultural producers to produce relatively expensive and high-quality equipment to improve conditions for the animals. This article was considered a method for effective fractionation of manure on pig farms to further obtain humus for soil fertilization. The optimal conditions for the performance of the presented gadget were identified, namely: the time spent by the manure mass in the rotor is 0.1, with a separation factor of 170 to 180, the partition for the filter is made of metal sheet with holes whose diameter varies from 0.8 to 1.5 mm and a thickness of no more than 1 mm. The device presented in the manuscript has several advantages in the form of automation, low energy consumption and cost, novelty, and high efficiency.

The article presents a theoretical justification for sorting corn ears on the developed plant and proposes a solution in the form of a working surface of varying curvature consisting of descending and ascending surfaces. The conditions under which the sparing mode is created for reloading the cobs are determined, the dynamic parameters for moving the cobs along the descending and ascending surfaces and by the grapho-analytical method are determined by intervals of their values corresponding to the sparing regime. The obtained theoretical dependences take into account the physical and mechanical properties of corn cobs.
