However, liquid nitrogen is seldom used in jet milling opera-tions due to the swift heat exchange between the material and the grinding gas. The grinding gas heats up the super-cooled feed stream, and the material loses its brittleness ... air classifier of a jet mill), and collection (e.g., plugging the

Jan 01, 2007 1. Introduction. Air jet milling, or more correctly fluid energy milling, uses high velocity jets of gas to impart energy to particles for size reduction. Albus [1] gives a brief history of air jet mills. The first versions, developed in the late 19th century, used a jet of compressed air

Mechanical Milling for Pharmaceuticals. Multi-Processing Systems for Size Milling and Classification. Micronization for Potent Compounds. Particle Size Characterization. Cryogenic micronization is particle size reduction using an air-jet mill chilled with liquid nitrogen. It is becoming a preferred method for producing finer particle size of compounds with a low brittleness and tacky or semi-solid in nature

Jet mill works on fluid energy. Consider a pancake spiral jet mill as an example. Micronizing and classification take place in a shallow, cylindrical chamber. High pressure air or steam is injected in this chamber through the specially designed nozzles placed at regular distance, on the peripheral wall. The axis of each jet is tangential to the

The fluidised bed opposed jet mill is the second most common type of jet mill. In this mill, the material to be ground is fed via a feed sluice. A product fluidised bed then forms in the grinding chamber, which is fluidised by the gas jets. From there, the particles enter the gas jets and are accelerated
