SUBSTANTIATION OF THE LINING PLATES MATERIAL FOR BELT CONVEYORS DRIVE DRUMS
The article is devoted to the issues of increasing the durability of the rubber ceramic lining of the drive drums of heavily loaded conveyor belts based on the rational choice of material for ceramic inserts of the lining cloth. The analysis of the nature of the interaction of ceramic plates with the conveyor belt, as well as the study of stresses caused in the plate under the action of operational loads, allowed us to identify a set of requirements for the mechanical properties of aluminum-oxide ceramics that ensure reliable operation of the drive and efficient operation of the conveyor. The article proposes grades of alumina ceramics, presents the main technological stages and conditions for the manufacture of plates that contribute to obtaining the required mechanical characteristics and porosity of ceramics, and also presents the results of bending and crack resistance tests of samples from the proposed grades of materials.
