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: sizeGenerally, filling the mill by balls must not exceed 30%–35% of its volume The productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length The optimum ratio between length L and diameter D, L:Ball Mill an overview | ScienceDirect Topics
