Jet mill working principle
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.
