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.

Classification

The classifier designs differ mainly in the mode of removing the underflow and the overflow slurries. Immersed spiral or rakes are generally used for underflow slurries and an open launder carries the overflow. Figure 13.1 is a sketch of a spiral classifier where the spiral conveyor is installed within the bowl. The spiral operates along the ...

Spiral Classifier Structure, Working Principle, Feature, …

Spiral classifier uses the principle of the proportion different of solid particles, so the precipitation speeds is also different in the liquid. Fine mineral particles float in the water and overflow; the coarse ore particles settle on the bottom of the channel. Material is discharged from the upper by spiral, so as to finish the grading work.

An operational model for a spiral classifier

Spirals are gravity concentrators used for the valorization of coal and heavy minerals. Coarse hematite iron ores in Canada are usually concentrated by spirals. Spirals classify the particles according to their size and specific gravity. Several mathematical models were proposed to simulate the operation of spirals using a balance between the various forces …

Spiral Classifier: Importance & Types

The main component of the spiral classifier is the spiral. According to its position in the tank and the level of the slurry surface, it can be divided into three types: low dam, high dam, and submerged spiral classifiers. The low dam spiral classifier is rarely used now; the high dam and submerged spiral classifiers are mainly used. 1.
