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.

Jul 24, 2009 · I struggle with the speeds and feed rates for "small" ball end mills (0.03125, 0.040, 0.0625) when cutting our typical tool steels such as P-20, A2, and H13. We are limited to a maximum spindle speed of 15,000 rpm.
Overflow Type Ball Mill
Overflow type ball mill is a kind of beneficiation ball mill whose name comes from its ore discharge method. The overflow type ball mill is widely used in cement, mineral, refractory material and other industries. According to the discharge method, it is also suitable for the beneficiation industry to grind fine ores or regrind concentrates.
