ball mill drum feeder efficiency temperature

hosokawa-alpine: S.O. - Super Orion Ball Mill

Ball mills are usually operated at 75% of the critical speed. The critical speed is the speed where, mathematically calculated, the grinding media would centrifuge out. Mills of 2 m in diameter therefore rotate in operation at about 23 revolutions per minute, which corresponds to a peripheral speed of 2.4 .
