description: This work is devoted to the study of the characteristics of the drum screen at a given technological load and the process of wear of the materials of the screen sieves. As a result of the work performed: 1.Theoretical studies of the drum screen have been carried out: - the energy and kinematic parameters of the drum screen, the design dimensions of its elements are determined depending on the parameters of the technological load and the material of the sieves of the screening surface. The dependence of productivity and power on the drum speed, layer height and material density has been established. - the equivalent stresses and deformations of the working surface of the drum are determined depending on the material of the sieves. The conclusion is made about the possibility of using the design and materials of the screen sieves for a given technological load. 2.Laboratory tests of a sample of the drum screen sieve material were carried out with reciprocating motion on a friction machine and a given load level. The magnitude of the friction force from the movement of a sample of nitrile rubber and the degree of deformation, as well as the microhardness and roughness of the abrasive body are determined. The study of the wear process during wear testing of materials is a promising direction in materials science and is aimed at improving technology and equipment in mechanical engineering.
