“…There is F. Bond's law, according to which total energy must contain the work of deformation and the formation of new surfaces. Bond's law assumes that energy is initially distributed over its mass and is proportional in sum 𝐷 3 , and from the moment of forming the crack on the surface is proportional 𝐷 2 .…”

“…The founder of physical and chemical mechanics P. O. Rebinder [11,2] believed that the closest hypothesis to the truth is in the middle between the assumptions of Rittinger and Kirpichov-Kick, and the work spent on grinding, in general, is the sum of two terms: А = σΔF + kΔV, (5) where σspecific energy attributed to a unit body surface; ΔFbody surface formed during destruction; kwork of elastic and plastic deformations, attributed to the unit volume of a solid bidy; ΔVthe volume of the body that has undergone deformation.…”

For the efficient functioning and successful development of the animal production sector, the key condition is correct feeding of animals. This feeding is only possible if enough feed is produced, nutrient losses during harvesting are reduced, and feed is correctly prepared for feeding. The introduction of concentrated feed helps to achieve a balance between energy, protein and amino acid content in the animal ration. Technologists compose and select components of feed rations based on the species, age group, morphological and biological characteristics of animals, as well as other factors. Despite the chosen technology and feeding strategy, concentrated feeds such as processed cereals based on wheat, barley, corn and other crops continue to be the main source of nutrients for animals. The quality of grinding concentrated feed is important for animal productivity. This treatment results in the formation of numerous particles with a larger surface area, which promotes faster digestion and better absorption. Grinding is one of the most high-energy processes used in animal feed technology. Since plant residues are structurally uneven, this makes it difficult to use conventional grinding methods efficiently, which reduces their energy efficiency and requires the use of several grinding stages with appropriate equipment. In order to ensure efficient processing of agricultural plant residues, it is important to create an appropriate technical infrastructure, given the significant energy costs associated with traditional processes of preparing biomass for granulation. To do this, it is necessary to conduct research aimed at solving the problem of energy-efficient grinding of structurally heterogeneous materials, in particular materials that contain a large amount of moisture. This is what determines the relevance of this research topic.
