Ball Mill Critical Speed - Mineral Processing 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 shells 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.

Usually the critical speeds are desired to be 10 to 20 above or below the operating speed range. However, there are many rotors that operate on top of the second critical speed due to sufficient bearing damping. Often attempts to elevate the 2nct critical speed by increased bearing stiffness leads to serious 1st mode stability problems.
