tue effect of speed in ball milling

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

Effect of ball size and powder loading on the milling

As the rotation speed increases kinetic energy of the balls increases which in turn shifts the optimum ball size toward a smaller value As the powder loading increases from 1 to 35 g at a given rotation speed and ball size the milling efficiency decreases monotonically
