— Nano mills are most efficient when the incoming particle size is smaller than the exit screen and no larger than the media. This means that the target particle distribution for pre-milling should be between 25 um and 100 um, a distribution that can often be achieved with a very short pre-mill cycle in a high-energy mill.

Heavier oversized particles are held in the grinding chamber by centrifugal force, until micronized to a desired size. Feed particle size is critical, restricted by the size of the feed injector. For mills of 200-300 mm, the feed size can be a maximum of 1.5 mm. For smaller-size mills, the feed size is correspondingly finer.
