Evolution of Laboratory Mills and Grinders Lab Manager

Evolution Of Laboratory Mills And Grinders Lab Manager

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 circle.The 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.
