Identification of Optimal Mill Operating Parameters during Grinding ...

Celik M.S. (1988) stated that the breakage rate of anthracite in ball mills exhibited an acceleration, particularly noticeable for long grinding times, due to extensive agglomeration of fines. The acceleration or deceleration of breakage rates of all individual size classes can be determined during wet grinding using the G-H...

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind and 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...
