An operational model for a spiral classifier - ScienceDirect

May 15, 2016 · 2. 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.

An operational model for a spiral classifier - ScienceDirect
