Apr 25 2018 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.
Apr 25 the speed of the mill was kept at 63 of the critical speed the face angle was varied from 90 to 111 degrees for the three types of configuration 1 2 and 4 as shown in the figure also the height of the lifter bar in configuration 3 was changed to observe the
