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.

Spiral Classifier Structure, Working Principle, Feature, …
Spiral classifier uses the principle of the proportion different of solid particles, so the precipitation speeds is also different in the liquid. Fine mineral particles float in the water and overflow; the coarse ore particles settle on the bottom of the channel. Material is discharged from the upper by spiral, so as to finish the grading work.
