Ball mill

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.

Calculating Mill Drive RPMs: Is Your Mill Up to Speed?

In order to know for sure all sections are matched and properly balanced, one must also calculate the speed for these smaller sections to the larger sections. The bottom throat diameter of each bottom driven roll, in each section, breakdown, fin and sizing, is the not only the drive point for these sections, but they also give reference to the "bottom" or "metal" line of the entire mill.
