Section Of Fine Grinding Mills

1970s in 1975 centrifugal mills were invented for ultra fine grinding by exploiting centrifugal forces generated by gyration of the axis of the mill tube in a circlethe mill charge motion depends on the ratio of the gyration diameter to the mill diameter varying from a motion similar to that of a conventional tumbling media mill to that of a vibration mill.
