Ball mills produce 1 to 50 ton/h power of which near about 70 to 90 percent would pass a 200 mesh screen and the energy requirement of a ball mill is about 16 kWh/t. In the case of the batchoperated mill, a measured quality of a solid to be ground is charged into the mill through an opening in the shell.

CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

A ball mill rotates its long shaft, and drive a jar which is placed on it. The friction of the rubber surface of the shaft can rotate the jar. The grinding beads (grinding balls) in the jar will constantly hit the sample due to gravity and mechanical force. After a long period of rotation and impact, the sample gradually changes from large pieces to small pieces, and small pieces to powder.

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. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls.

Working Principle of a SAG Mill. The rock and grinding media are placed in the mill and rotated, causing the grinding media to tumble and crush the rock into smaller pieces. The mill operates in a closed circuit with screens that size the ore and send it back to the mill for further grinding. The product from the mill is then sent to a cyclone ...
