Mill Critical Speed Calculation
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.

Critical speed is C.S. = 76.63 / 11^0.5 = 23.1 rpm Ball and SAG Mills are driven in practice at a speed corresponding to 60-81% of the critical speed, the choice of speed being influenced by economical considerations. Within that range the power is nearly proportional to the speed. Mill rotating speed impacts grinding rates.
