Mathematical modeling of the process of grinding grain materials

Abstract

The problem of providing peasant (farmer) households with the means of production is currently very relevant, since the existing prototypes of equipment do not always satisfy both the necessary and sufficient conditions for its use. With small production volumes, it is rather difficult to ensure a high load factor and uniformity of high-performance equipment. High prices for energy resources in agricultural enterprises do not allow producers to reduce prices for their products, as a result, it negatively affects, first of all, consumers. Consequently, in the modern conditions of the functioning of peasant (farmer) farms, the development of new and improvement of existing means of mechanizing the production process, corresponding to the foundations and principles of resource conservation, comes to the fore. Among the means of mechanization for grinding grain materials, the most common are universal impact crushers with articulated hammers. They are able to grind various types of raw materials, are relatively simple in design and convenient in maintenance and operation. Their design allows easily changing wear parts (hammers, decks, grates). At the same time, modern designs have significant disadvantages such as the following ones: high metal consumption and energy consumption of installations, uneven grain size distribution with an increased content of dust particles, intensive wear of working bodies and the associated decrease in productivity and quality of material grinding.
