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.

By means of a flange type torque sensor, the torque signal is recorded when the motor is driving a constant torque load, (Fig. 1(a)), and a ball mill, (Fig. 1(b)). The presence of an oscillating component of around ± 2 Nm, superimposed to the average value, can be observed in the case of constant torque load.
