Mechanics of the grinding media in ball mills with longitudinal and transverse motion of the grinding media

摘要

This article analyzes the problems of perfecting grinding equipment for large-scale production - cement, ore, coal. An improved design of a ball mill, equipped with internal energy exchange devices, is considered and there is a description of the technical and economic indicators of a standard and an improved mill. The method of calculating the kinematics of motion of grinding media in a mill with longitudinal and transverse motion of the grinding media is described and formulae for determining the effective forces are presented. Equations are given for determining the velocity regimes describing the motion of the grinding media.
