• ## 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 The mill speed is typically defined as the percent of the Theoreticalcritical speed of ball mill formula and derivation,The priority in sizing industrial ball mills by means of accurate measurements of the but on the basis of more simplified similarity considerations the derivation of an. critical speed equals the square root of the Froude-number. Thus tumbling mills may be derived from the various empirical power-draw-formulas
