Grinding Mills: Ball Mill & Rod Mill Design & Parts

Grinding Mill RPM – Rotating Speed Grinding Mill speed is one of the factors affecting the character of the cascading charge. As shown in the illustrations, the lower the percentage of critical speed, the smoother the flow of balls from top of charge to bottom. Higher percentage of critical speed is used for impact grinding of large feed.
