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.

Ball mill Most ball mills, even in primary applications, have a finer ore feed size; this requires some impact but not enough to increase the media consumption or even break the liners. Typically, a ball mill lining has a more rounded profile, often like a sine wave, and the size of the waves is selected based on the size of grinding media used.

Mill critical speed is defined as that rotational speed at which an infinitely small particle will centrifuge, assuming no slippage between the particle and the shell. The critical speed, Nc, in revolutions per minute, is a function of the mill diameter, D, expressed as: Nc = 42.3/√D (meters) or Nc = 76.63/√D (feet)
