Classifier Ball Mill. There is also on the market a rib-cone screening ball-mill whose "classifier," as it may be termed, is part of the mill. Capacities for prospectors are 2 to 4 and 4 to 8 tons through 35 mesh in 24 hours, requiring 1½ to 3 horsepower. The screen is as the discharge end of the mill.

The profiling of the shell lining plates creates the movement of the ball charge, which causes the grinding of the material. It is therefore essential for effective grinding in the mill and far more than just a wear part. The exact profile shape has to be defined depending on the ball sizes used, the rotation pace and the mill diameter.
