Ball Mill Critical Speed - Mineral Processing Metallurgy

The Formula derivation ends up as follow: Critical Speed is: N c =76.6(D 0.5) where: N c is the critical speed,in revolutions per minute, D is the mill effective inside diameter, in feet. Example: a mill measuring 11’0” diameter inside of new shell liners operates at 17.3 rpm. Critical speed is. C.S. = 76.63 / 11^0.5 = 23.1 rpm. Ball and S Mills are driven in practice at a speed ...

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 of 50-90% of the critical speed, the factor being influenced by economic consideration.
