One of the directions of development of the exploration, oil and gas and mining industries is to increase the productivity of equipment by increasing the technical level and production efficiency. Aluminum production is one of the fastest growing industries. In search of new directions for the development of aluminum production technology, there are numerous studies aimed at the widespread industrial introduction and modernization of electrolyzers. The alumina acceptance unit of the bucket elevator at the electrolysis plant provides for the transportation of alumina, which gets into the moving parts of the elevator chain, which leads to their jamming and premature accelerated wear of the connecting bushings. Based on computer modeling using the APM FEM program, a study of the stress-strain state of two variants was performed: plate and anchor chains with the application of acting loads, namely, the weight of the bucket with the load and the chain tension. As a result of statistical calculation, the equivalent Mises stress decreased by 2.44 times and the safety margin coefficient increased by 2.5 times. Thus, the replacement of the plate chain with the anchor of the alumina acceptance unit of the bucket elevator based on studies of the stress-strain state will increase the service life by 2.5 times and reduce the cost of preventive maintenance.
