Aug 06, 2015 The work index and the size of the cyclone feed will determine the ratio of ore that is returned to the ball mill for further grinding. A ball mill operates more with the grinding surface action of the balls than the impact form of grinding that the rod mill uses. Taking this into account you can see that if the rod mill doesn’t reduce the ore to a size that the ball mill can reduce quickly, the circuit

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
