Progressive activator lining - Christian Pfeiffer

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.

Grinding Balls and Other Grinding Media: Key …

Ball chips from flaked, poor quality grinding balls result in shorter operational life of pumps, hydro-cyclones, and recirculating pipes. Grinding balls may be too light to have the sufficient kinetic energy to break rock. Mill flow rates are reduced. Inferior grinding balls cause peening when they are hammered against the discharge rate.
