The air classifier mill process. An air classifier mill, also known as an air classifying mill, uses airflow to separate particles by size. The mill consists of a grinding chamber, a classifying wheel, and a fan. The raw material to be ground is fed into the grinding chamber, which is impacted by a highspeed rotor fitted with hammers or pins.

Gravitational air classifiers. With the use of air flow, gravity and sharp directional changes, the gravitational classifiers perform accurate separations of material from 1,700+ microns down to 150 microns. Coarse particles are conveyed by gravity through a valve at the bottom of the unit, and fine material is conveyed by air to a fabric filter.

AIR SEPARATORS. Introduction. Separators are utilized in a closed circuit grinding system for the purpose of separating (classifying) the fine and coarse particles of the feed. The fine particles are passed through the separator to become finished product while the coarse particles are returned to the mill as rejects for further grinding.
