### 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 Mill Critical Speed Determination The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface This is the rotational speed where balls will not fall away from the mill's shell : Mill Critical Speed DeterminationThe formula to calculate critical speed is given below N c = 42305 /sqt(Dd) 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 5090% of the critical speed, the factor being influenced by economic considerationMill Critical Speed Formula Derivation Grinding
