Jet mill working principle - Jet mill

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. Consider a pancake spiral jet mill as an example. Micronizing and classification take place ...

Back to Basics Hammer Milling and Jet Milling Fundamentals

A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding

The Operating Principal. P ulverization takes place in the central chamber of the Micron-Master® jet energy mill as the process material is driven at near sonic velocity around the perimeter of the toroidal chamber by multiple jets of air or steam. No grinding media is involved. Size reduction is the result of the high-velocity collisions between particles of the process material itself.
