Ball Mill Critical Speed. 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.

Effect of Speed and Filling on Power. In this section, a 0.545-m x 0.304-m ball mill is simulated to study the combined effect of mill speed and filling on the power draft of the mill. Mill operating speed and filling, among other things, are known to affect the power draft. Mill performance is at its best when these two operating parameters
