Jet mill - Wikipedia

The air classifier mill uses air to carry the product through the fine grinding milling machine and classifying process. The feed material is conveyed through the pneumatic feed duct into the grinding zone. The main airflow enters the mill through the main air inlet underneath the grinding disc which rotates with tip speeds of 70 to 120 m/s.

Jet mill working principle - Jet Mill | Air classifier mill

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.
