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.
