If the shell liners are of the

Design Method of Ball Mill by Sumitomo Chemical Co., Ltd ...

A ball mill is one kind of grinding machine, and it is a device in which media balls and solid materials (the materials to be ground) are placed in a container. The materials are ground by moving the container. Because the structure of ball mills is simple and it is easy to operate, and so they are widely used.

MODULE #5: FUNCTIONAL PERFOMANCE OF BALL MILLING

For any process, including ball mill circuits, we can say that output equals input multiplied by efficiency*. Output = Input x Efficiency In a ball mill circuit, the "output" can be defined as the production rate of fines of the circuit. As for any output, ball mill circuit output is a function of both its inputs and efficiencies.
