“…Grinding is often associated with limiting overloading of the grinding equipment [3]. It is also possible to pay attention to the organization of production and the optimal choice of the type of technological equipment [4]. At the same time, the efficiency of forage grinding has been proven in previous studies [5].…”

In the conditions of farms, it becomes necessary to grind feed that has a different degree of moisture. Therefore, the choice of universal working bodies is the object of research, and the theoretical determination of the average size of pre-crushed feed particles is of great scientific and practical importance and is a problem that needs to be solved. Proceeding from this, a constructive-technological scheme of a grinder with a universal grinding working body is proposed. The grinding apparatus is equipped with a hammer working body which has cutting edges. In this case, hammers with cutting edges crush the wet mass, and also create an air flow and work as flow accelerators at high speed. As a result of theoretical studies, the steps for arranging these working bodies were determined. Analytical expressions are obtained for determining the average length of pre-crushed feed particles depending on the distance between the faces of replaceable knife working bodies, i.e. from the step of arranging them in rows. At the same time, the calculation results showed that with a distance between the faces of replaceable hammers of 20 mm, the value of the average length of the grinded particles was 38.38 mm. The average size of pre-crushed particles from feed raw materials intended for farm animals was 37.64 mm, i. e. the difference between theoretical and actual value is only 2.0 %. This proves the reliability of the obtained analytical expression, which provides the determination of the main parameter of the grinding working body, i. e. spacing of radial knives in rows. The proposed method of determining the average length of crushed particles allows theoretically finding and planning the required particle size

“…The first development effect arises from the organization of production itself on the basis of an optimal combination of basic principles [17,18,19,20,21]. The second effect of development arises and enhances the first one based on the correct choice of types of technological equipment and structural schemes of its location, which leads to the alignment of feed flows in stable subsystems and narrowing the spectrum of "white noise" dispersions in transition zones, therefore, improving the granulometric composition of the output product and reducing energy consumption.…”

This paper aims at finding a solution to the main problem of feed production: increasing the efficiency of the production process while improving the quality of products. The article aims to develop an adequate mathematical model of the technological process of combined feed industrial production. The authors have developed the theoretical background for describing this process on the basis of flow models within the framework of the original “three effects” concept, a stochastic model has been created taking into account the preservation of the exergy balance of the technological system. The main research tool is the apparatus of system analysis and the theory of random processes. An engineering-mathematical calculation of the parameters of the constructed model was performed, verification of the stochastic model of the technological process of preparing compound feeds in laboratory conditions was carried out. As a result of the research, the authors established the possibility of controlling the stochastic feed flow in all subsystems of the production technological system, outlined ways to solve the problem of increasing the efficiency of feed production by reducing energy costs and improving the output product granulometric composition.

Introduction. For small farms, an urgent task is to adapt standard compound feed machinery for producing the specified local feeds. It is necessary to use sunflower seeds for producing oil and fat sunflower meal for cattle. There are no universal presses suitable for producing sunflower meal. The process of crushing sunflower meal also causes difficulties. Therefore, we need a set of machines for this operation. Aim of the Study. The article is aimed at developing a mathematical model for producing sunflower meal on the field plot and feed concentrates with the use of the compound feed machinery, and for determining the optimal field plot and machinery with minimal technical and economic indicators. Materials and Methods. The developed algorithm in view of the mathematical model is implemented in the Microsoft Excel 2016 program. The results and calculations for the choice of rational option of machinery for producing sunflower meal on a field plot are presented in the text of the article. Technical and economic indicators and costs of the workshop and its operation are calculated according to the recommendations of Doctor of technical sciences, Professor V. V. Konovalov, but taking into account the expressions obtained for technological calculation. Results. A mathematical model for producing concentrated compound feed is developed. The calculations carried out for the choice of a rational option of the field plot and the compound feed machinery showed the schemes of machines that meet the objectives of the study. Discussion and Conclusion. For the conditions under consideration, an effective option among the presented field plots, from an economic point of view, is the field plot and compound feed machinery presented at the scheme 1 (table 1). Technological calculation of the sunflower meal production plot and the compound feed machinery was carried out based on the developed algorithm in view of the mathematical model for producing concentrated compound feed and the program for its implementation, their technical and economic indicators, and the costs of the workshop and its operation were calculated, and the rational option of the field plot and the compound feed machinery were selected. The economic effect of the selected field plot and compound feed machine was achieved by reducing annual operating and other direct costs, reduced costs.
