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. Below 50% CS too little energy ...

How to Convert RPM to Linear Speed | Sciencing
About the Author. Photo Credits. Performing a conversion from RPM to speed in a linear direction involves two steps: first convert the RPM to a standard angular velocity, and then use the formula v = ωr to convert to linear velocity. You divide the figure in RPM by 60, multiply by 2π and then multiply by the radius of the circle.
