The Stirred Media Detritor, (SMD), is a grinding device used for fine and ultrafine grinding applications in mineral processing. The SMD has a vertically orientated shell that supports a shaft, with protruding impeller arms for agitating the charge. There is currently limited understanding of charge structure and motion in the SMD, particularly the interaction of the media and the slurry.

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 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.

The VXPmills are designed for fine and ultra fine grinding applications. In practice, the mill performs best when the feed has a normal distribution. However, the mill has been used to preferentially grind the coarser "hump" in bimodal distributions without over grinding the finer part of the distribution. Grinding efficiency is affected by ...
