It was found that the standard mill suffered a very high wear rate, with the disks being severely worn within 12 hours.

In a batch machine, a known quantity of the material to be ground is charged into the mill through an opening in the shell. . The opening is then closed and the mill is rotated for a certain time, and finally

Ball mill

A ball mill is a type of grinder used to grind or blend 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. A ball mill consists of a hollow
