Derive The Equation Of Critical Speed Of Ball Mill

Ball Mill Critical Speed Mineral Processing & Metallurgy

A Ball Mill Critical Speed (actually ball, rod, AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell’s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the Theoretical

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.
