An operational model for a spiral classifier

Spiral classifiers. A typical spiral classifier is shown in Fig. 1. The geometry of a spiral is characterized by the length or number of turns, the diameter, the pitch and the shape of the trough (Burt, 1984). The spiral feed is a mixture of water and ground particles that is gravity fed at the top of the spiral.

How Air Classifier Mill Works

The Air Classifier Mill operates on the principle of impact grinding. It consists of a grinding chamber, an air classifier, and a blower. The material to be ground enters the grinding chamber through a feed inlet. Inside the chamber, a series of rotating hammers or pins impact the material, causing it to break into smaller particles.
