A fluid energy mill is also known as a pulverizer, micronized, or jet mill. It is used for fine grinding and close particle size control. The reduction of the particles takes place by the attrition and impact mechanism by the air or inert gas introduced through the nozzles present in the chamber. This mill is mainly used to grind heatsensitive ...
