Abstract

In this article the results of the experimental studies of dependence of stress in the vibrating feeder container, time of impact and protective layer properties are given. This research was performed on the laboratory bench modeling vibrating feeder container. It is shown that the protective rubber lining of vibrating feeder reduces stress concentrations in the contact zone of impact of vibrating feeder container with falling collision boxes vibratory feeder with falling chunks of ore is more than five times, it reduces the weight of the moving parts of the machine and the drive power.
