Jun 19, 2015· The effect of Ball Mill RPM speed going from subcritical to supercritical helps understand the Ball Mill Working Principles of ballonball VS ballonshell grinding. The Motion of the Ball .
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.
