The Rotating Speed Has Great Effect on the Ball Mill .

It has been proved that the rotating speed has real effect on the production of the ball mill. In general, the critical speed of revolution will reach 76% to 88% when the ball mill is working. However, the most common rotating speed of the ball mills made in China can only reach 75% to 80% which is lower than the theoretical calculating value.

Variables in Ball Mill Operation | Paul O. Abbe®

The formula for critical speed is CS = 1/2π √ (g/ (R-r) where g is the gravitational constant, R is the inside diameter of the mill and r is the diameter of one piece of media. This reduced to CS = 265.45/√ (R-r). Dry mills typically operate in the range of 50%-70% of CS and most often between 60%-65% of CS.
