Spiral concentrator is the key operating unit and is widely used for concentrating different minerals and coal. Normally in mineral processing a rigorous and costly experimental evaluation of laboratory and pilot-scale equipment trials are conducted for accessing the performance of any unit operation. So, developing a low cost, time saving tool ...

Spiral classifier. Another mechanical classifier is the spiral classifier. The spiral classifier such as the Akins classifier consists of a semi-cylindrical trough (a trough that is semicircular in cross-section) inclined to the horizontal. The trough is provided with a slow-rotating spiral conveyor and a liquid overflow at the lower end.

The typical spiral unit consists of a spiral conduit with a modified semi-circular cross section. As the slurry flows down the spiral, those minerals with highest specific gravity move to the inner edge of the spiral while the light material moves upward to the outer edge of the spiral. A full size spiral concentrator is shown in Figure 2.
