Position Of Balls In Ball Mill

Ball Mill Positioning. 2benshaw.com. Ball Mill Positioning. Introduction. Ball mills are used in many industries to grind coarse material into a finer powder. A ball mill typically consists of a horizontal cylinder partly filled with steel balls that rotates on its axis, imparting a tumbling and cascading action to the balls. In cement manufacture, clinker is fed into the mill and is crushed by the impact of the balls and ground by attrition between the balls

    The size of the disintegrated particles also decreases as the discharge outlet is approached and the energy used decreases. In a conical mill, most big balls take up a position in the deeper, cylindrical part of the body; thus, the size of the balls scales down in the direction of the discharge outlet
