Mill Critical Speed Calculation

Mill Critical Speed Calculation

Oct 15, 2015 The mill was rotated at 63 of the critical speed. The position of the balls at the end of five revolutions is shown in Figure 2. It is seen that, using a low coefficient of friction at the walls, balls tend to flow down the surface of the charge, and a “toe” begins to form. As the friction at the wall increases, cataracting motion is observed.

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.
