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.

Classification
Thus, classifiers with a 300 mm spiral diameter revolve at about 8–20 rpm, while the 2000 mm diameter spirals rotate at about 2–5 rpm to give a sand conveying speed of 2–3.5 m/s. The raking capacity of the large classifiers is approximately 200 t/h, while smaller classifiers have raking capacities as low as 1.5 t/h.
