Developing cutting-edge technologies and dedicated machinery for processing and allocating roughage relies heavily on understanding its physical and mechanical behavior. Existing technical sources reveal a notable scarcity of detailed information on the distinct properties of coarse fodder produced within Uzbekistan's specific agro-climatic environment. Therefore, this research focuses on assessing the essential physico-mechanical properties of regional roughage to support the engineering of high-performance processing equipment. The applied methodology encompasses statistical evaluations, particle-size and crushing-modulus analyses using a ball classifier, and compliance with official material-testing protocols. Experimental data demonstrated that the friction angle of wheat straw against a steel interface reaches 30° longitudinally and 32° transversally. In comparison, alfalfa exhibited values of 29° and 30.6° for the respective directions. These insights indicate that incorporating steel contact zones into processing apparatuses improves material flow and refines overall distribution efficiency.
