Ball Mill Grinding Theory - Crushing Motion/Action Inside

The proper operating speeds of ball-mills vary inversely as the square-root of the diameters. The proper operating speed of a ball-mill increases as the size of the ball load increases. Due to interference between the balls, the volume of the charge should not be over 60 per cent, of the volume of the mill.
