Ball Mill - an overview | ScienceDirect Topics

Generally, filling the mill by balls must not exceed 30–35% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length. Optimum ratio between length L and diameter D, L: D is, usually, accepted in the range 1.56–1.64.

Ball mill - Wikipedia

24/7/2004· 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.
