Ball mill - Wikipedia

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 cylindrical shell rotating about its axis. The axis of the ...

Advantages and Disadvantages of Particle Size Reduction ...

Mills used to grind will operate with higher roll speeds - 1,500 Ft/min (7.5 M/sec) up to 3,000 Ft/min (M/sec) with roll speed differentials. Roll speed differentials simply means one roll turning faster than the other and is usually described in the form of a ratio, slow roll speed expressed as 1. For example, rolls operating at 1.5:1 differential with a fast roll speed of 1,000 RPM would ...
