Grinding of cement clinker has been traditionally performed by the ball mills which can either be open circuit or closed circuit with an air classifier. Selection of right mill for the specified duty is the most critical for circuit design, since it has the highest capital and operating costs.
Over the past decade the growth and development of mining projects have increased dramatically, as have the requirements to design and develop grinding circuits, mainly in the field of SAG and ball mill circuits. There are several design methodologies available in the market or through the usemercial software or expert consultants.

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
