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 heatsensitive and waxy material because no attritional heat is generated. Jet mill works on fluid energy. Consider a pancake spiral jet mill as an example.

Jet mills. Until the introduction of jet mills in 1936, dry grinding in the subsieve range of 625 mesh (20 microns) to 2,500 mesh (5 microns) was impractical. To create fine particles with a narrow PSD, previously manufacturers had to mill the material, sieve out the oversized particles, and remill. The process was long, expensive, and

What Is Jet Milling?

Jan 28, 2020 · Jet milling is a process of using highly compressed air or other gasses, usually in a vortex motion, to impact fine particles against each other in a chamber. This gradually reduces them in size, resulting in powders that have particle size dimensions as small as one micron across, or 50100 times smaller than the width of a human hair.
