Abstract
The development of new technologies and technical means for grinding and distributing roughage is impossiblewithout determining the patterns of change in their physical and mechanical properties. Analysis of scientific andtechnical literature shows that the physical and mechanical properties of roughage have not been sufficiently studied inthe conditions of Uzbekistan. The purpose of the study is to study and analyze the physical and mechanical propertiesof roughage grown in Uzbekistan. In the course of research, methods of statistical analysis, methods of determiningthe mikrometric composition and crushing modulus of the product crushed with a ball classifier, as well as the methodsspecified in the existing regulatory documents were used. According to the results of the research, the angle of friction ofwheat straw on the steel surface is 30o in the longitudinal direction, 32o in the transverse direction, and 29o and 30.6oof the alfalfa, respectively. when the surfaces are made of steel, they provide faster movement of nutrients along them.
