The CRITICAL SPEED is the maximum revolutions per minute that the mill can revolve and still maintain performance. Naturally, the opposite is true as well, if the speed, is too slow the material will cascade too soon losing both impact energy and grinding motion. The size of the grinding media and the speed of the mill will have to be balanced
