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.
