subject: Ball mill Features and Working principle [print this page] There are step liner palates or wave liner palates in the first cell which has been loaded various steel spheres of different scales. When rotating, the drum causes centrifugal force that brings the steel spheres to a certain height and then the spheres drop to impact and grind the materials. After the rough grinding in the first cell, the qualified partials will enter into the second cell through a single division plate .There are flat palates welded on the inner wall of the second cell, as well as steel spheres. The materials will be further grinded in it and at last the qualified granularities will be discharged through the unload part. Then the whole process is completed.
