Keeping this in mind, ball mills were designed by engineers for blending and grinding materials useful in manufacturing of paints, pyrotechnics, ceramics, etc. Essentially, a ball mill is a hollow cylindrical chamber that is fixed to an axis. Upon operation, it rotates by its axis on a set speed and the balls occupying its chamber space collide ...

1. Grinding media wears and reduces in size at a rate dependent on the surface hardness, density and composition of the ore.
2. Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter.
3. Other factors include:
