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
The S-type classifiers have almost gone out of use. The maximum lengths of H-type classifiers are about 14 m with widths of 0.5–7 m and spirals up to 2400 mm in diameter. The speed of rotation of the spirals varies inversely with size. Thus, classifiers with a 300 mm spiral diameter revolve at about 8–20 rpm, while the 2000 mm diameter ...

Classifiers for gold prospecting and gem hunting come in several shapes and sizes to help classify paydirt into a size that is easier to process. Our most popular classifiers are 14" across and fit on top of a five-gallon bucket. This allows one person to shovel paydirt onto the classifier and the other person to shake it down to size.
