Spiral separator - Wikipedia

A spiral separator may process a couple tons per hour of ore, per flight, and multiple flights may be stacked in the same space as one, to improve capacity. Dry Spiral Separators. Dry spiral separators, capable of distinguishing round particles from nonrounds, are used to sort the feed by shape.

Spiral Classifier for Mineral Processing

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 which 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.
