The spiral classifier such as the Akins classifier consists of a semi cylindrical trough inclined to the horizontal. The trough is provided with a slow rotating spiral conveyor and a liquid overflow at the lower end. The spiral conveyor moves the solids which settle to the bottom upward toward the top of the trough.
Gold Extraction, Gold Cyanide, Gold Manufacturing Process . Taking the gold cyanidation plant with processing capacity of 100000 tons per year and gold grade of 7.5 g/t as an example, gold CIL process can save the investment cost of 486000 than the CIP process, reduce the capital backlog of 201700, save and recycle capital of 675100 in advance excluding the cost of activated carbon.
This concentrator is a spiral conduit of modified semi circular cross section, with outlets for removal of concentrate and middling. Pulp is introduced at the top of the spiral. As the pulp follows the spiral channel, lighter particles in the pulp stream move outward and upward into the fast moving part of the pulp stream.

Principles of Spiral Gravity Classification by David Kirk INTRODUCTION Gravity separation of shot particles is of fundamental importance for peening. From a commercial viewpoint it is the basis of several methods for separating acceptable from unacceptable shot shapes i.e. classification. The commonest such method is probably spiral gravity ...
The spiral classifier is also a mechanical classifier. It is made by combining a gravity settler of rectangular section with a sloped transport spiral for the sediment. It consists of a semi cylindrical trough inclined to the horizontal.
Spiral Classifiers. The shape of the spiral classifier tanks is usually rectangular . The feed is introduced at a position about halfway along the length of the settling tank. The tank slopes range from 14° to 18°. The slope is adjusted such that the top end is higher than the height of the overflow . The spirals impede the downward slurry movement resulting in some build up.
