A ball mill is a kind of grinder that grinds and blends materials for the purpose of mineral processing, paint production, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: the balls are released from the top of the shell and then crush and grind the material to fine powders.

material and geometry of the cylindrical part (Mellmann 2001). Since the diameter of the mineral material must be reduced by the grinding process in the ball mills, it is nec-essary to operate the drum in the cascading regime, which favors the breakage by abrasion, or cataracting, which favors the breakage by impact. These two regimes have in ...

The higher break point is reserved for harder wet grinding materials such as enamel as well as dry materials. This angle of break is also determinate upon the size of the mill. Since grinding actions in a larger mill are more severe than that of a smaller mill, the angle of break should be lower for the larger Mills than the smaller.
