A semi-empirical mathematical model for a spiral classifier is proposed in this paper. The model is based on the observations of the movement of particles within the trough of a spiral and makes use of several hypotheses that still need to be validated …

The spiral classifier can be divided into three types: high dam type, low dam type and submerged type. 1). High Dam Spiral Classifier. The high dam type spiral classifier means that the overflow dam is higher than the spiral axis of the spiral, but lower than the upper edge of the spiral at the overflow end.

Gravity Spiral Concentrator Working Principle. The gravity spiral circuit is designed to extract and concentrate "coarse gold' from the recirculating load in the mill grinding circuit and hence prevent a build-up within that circuit and the eventual escape of some of that gold into the C.I.L. tanks and thereon into the final tails. (See fig. 4)

But this is not absolute. When the grading particle size is very fine (such as 0.037mm), the grading efficiency of the hydrocyclone is higher than that of other grading equipment. The footprint of a hydrocyclone is significantly smaller than that of a spiral classifier. Usually, the hydrocyclone occupies only 1/30-1/50 of the spiral classifier.
