Upon the theory of the motion of materials in screens and conveyors

Abstract

One of the questions of the theory of screens and conveyors consists in the study of the motion, with friction, of the particles of some material on a surface which also performs a certain movement, the latter being indicated beforehand. For this purpose, one has to form differential equations concerning the motions of materials in the most general case of the movement of the screen and then to apply them to the case of plane motion, which is of practical importance. Lastly, there are indicated some particular cases of integrability of the differential equation obtained.
