Normal operating speed is kept at 70% of critical speed hence by this criteria our ball mill operating speed should be = 0 70 x 29 92 i e 21 This isinfact the actual RPM of our roaster ball mill From above discussion it is clear that speed of the ball mill is decided by diameter of ball mill We can not change the speed of ball mill without affecting grinding action

Ball mill - Wikipedia

A ball mill is a type of grinder used to grind, blend and sometimes for mixing of 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 rotati
