Critical Speed_. When theball mill cylinderis rotated, there is no relative slip between thegrinding mediumand the cylinder wall, and it just starts to run in a state of rotation with the cylinder of themill. Thisinstantaneous speedof themillis as follows: N0 —-mill working speed, r/min; K’b —speed ratio, %.

Mill Critical Speed Formula Derivation - Grinding
The formula to calculate critical speed is given below. N c =42.305/sqt(D-d)N c= critical speed of the mill. D = mill diameter specified in meters. d = diameter of the ball. In practice Ball Mills are driven at a speed of50-90% of the critical speed, the factor being influenced by economic consideration.

Critical speedis. C.S. = 76.63 / 11^0.5 = 23.1 rpm.BallandSAG Millsare driven in practice at aspeedcorresponding to 60-81% of thecritical speed, the choice ofspeedbeing influenced by economical considerations. Within that range the power is nearly proportional to thespeed.Mill rotating speed impacts grinding rates.
