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.
