About the theory of the drum separator and some of its analogies

Abstract

The problem is to study the motion of a particle moving under the influence of gravity and in the presence of friction along the outer surface of a circular cylinder rotating around a horizontal axis. The problem under consideration finds application in some issues of mining and processing, namely in the theory of a drum separator, used for ore enrichment, as well as in the theory of a drum dumper, which is intended to unload material moved by a belt conveyor at a certain point. The results obtained make it possible to clarify the above theories, which are usually presented in technical manuals.
