The normal specific rates of breakage vary with mill speed in the same way. However, the maximum in power occurs at different fractions of critical speed from one mill to another, depending on the mill diameter, the type of lifters, the ratio of balltomill diameter, and the ball and powder filling conditions.
May 18, 2013· The critical speed of various ball mills is in direct proportion with its diameter, the absolute figure of critical speed is hard to calculated, and now only the calculation formula on critical speed in theory is widely used. When the nonsmooth lining plate is used, the filing ratio of ball load is among 40 percent~50 percent.
The theoretical critical speed of a ball mill is the speed at which the centrifugal force is sufficiently large to cause a small particle to adhere to the shell interior for a full revolution of the mill. The common range of mill speeds is 65% to 80% of critical, depending on mill type, size and the application.

Grate discharge mills give less excessive grinding compared to overflow mills and are best suited to grinds to 150–250 μm. In Figure C, the discharge opening is at the centre of the mill, while the feed is from both ends of the mill. The mills are therefore designated as a Centre Periphery Discharge mill.
