Ball mills normally operate with an approximate ball charge of 30%.
since the air-filled, rubber-and-cord actuating tube automati-cally compensates for friction shoe wear. The drum type design assures wear due to dragging. The reason: centrifugal force acting on the clutch shoes results in total disengagement when air pressure is released. An example of Airflex® clutch service life is given by one mill
