Onthe steady- state regime of a ball mill

Abstract

In a previous work devoted to the theory of a cylindrical ball mill, I studied the initial period of unsteady motion of the balls. If the angular velocity of rotation of the drum remains constant, then the regime of the ball mill after some time can be considered steady, and the magnitude and direction of the velocity of different balls passing through one and the same point in space do not change over time. We will talk about the outer row of balls. The same reasoning applies to other rows, if we make the assumption that the relative motion of the different rows is independent. This assumption, of course, requires additional research. The ball mill theory, which is usually used in practice, is approximate. The subject of this work is to refine the usual approximate theory of a ball mill.
