Spirals AKA-SPIN: for gravity separation of minerals
The slurry (10% – 40% solids depending on application) is fed into the spiral from the top. Spread on the spiral surface, it moves down by gravity. A transverse flow is superimposed to the main flow downwards. This combination results in a separation of the particles contained in the suspension, depending on their density.

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 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.

What is Spiral Classifier in Mineral Processing?
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.
