2015-10-15 · 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 of a cement mill kahla.pl
