Jet mill working principle

Jet mills operate in compressed air gas or high pressure superheated steam Jet mills have no moving parts thereby eliminating contamination due to contact with external grinding media It is also an ideal process to grind heat sensitive and waxy material because no attritional heat is generated Jet mill works on fluid energy.
