01/12/2013 As the rotation speed (rpm) increases, kinetic energy of the balls increases, which, in turn, shifts the optimum ball size toward a smaller value because the negative influence is alleviated. As the powder loading increases from 1 to 35 g at a given rotation speed (rpm) and ball size, the milling efficiency decreases monotonically. This phenomenon is interpreted to be resulted from (1) the
