Working principle of jet mill
A jet mill is a milling machine that uses high-speed compressed air or gas jets to impact particles and reduce their size. It is commonly used in the pharmaceutical, chemical, and food industries for particle size reduction. The purpose of a jet mill in particle size reduction is to finely grind and disperse solid materials into smaller particles. By …

Low-Pressure Jet Milling
Jet mills are named from their source of grinding energy: compressed gas expanded through a nozzle or nozzles to create a high velocity gas jet. While there have been many variations of equipment designs using this base technology, modern fluidized bed jet mills with internal classification show many benefits above other types of jet mills.

Types of Jet Mills and Their Differences
The spiral jet mill is a type of jet mill that operates by using a high-pressure air or steam to create a vortex that grinds and mills the materials. The spiral jet mill is unique in that it has a spiral-shaped nozzle that creates a more uniform vortex, which results in a more efficient grinding and milling process.

Fluidized Bed Opposed Air Jet Mill
Fluidized Bed Opposed Air Jet Mill: After the compressed air is filtered and dried, it is sprayed into the grinding chamber at high speed through the Laval nozzle. At the intersection of multiple high-pressure airflows, the materials are repeatedly collided, rubbed, and sheared to be crushed. The crushed materials rise with the suction of the fan.
