### 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.

### High-intensity centrifugal milling — A practical solution

01/04/1988 This paper introduces a new concept in centrifugal mill design for industrial-scale ball milling and autogenous milling. Based on the principle of a high-speed nutating motion of the grinding chamber, grinding rates in the mill are intensified by the action of a mechanically-induced rotating acceleration field much greater than gravity.
