A spiral classifier is a type of mechanical classification equipment used in gold mining and processing plants. It is also known as a spiral concentrator, spiral separator, or screw classifier. The spiral classifier is designed to perform the size classification of ore pulp, based on the settling velocity of particles in a liquid medium.

spiral classifiers -considering theirapplications and costs. Although in use for decades in the mining industry, spiral classifiers have lost a lotoftheirimportance due to the development ofcyclones. This trend, however, is now being reversed, and in the last few years there has been an increasing interest in spiral classifiers, in view oftheir

Introduction. The processing of heavy minerals and coal is often carried out using spiral classifiers. Processing of iron ore to separate coarse iron oxides such as hematite from light gangue mineral, such as quartz, is carried out in circuits with several hundreds of rougher, cleaner and re-cleaner spirals (Bazin et al., 2014).

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 ...

The spiral classifier separates the shaker table tailings into fine and coarse fractions. The coarse material is directed back to the grinding circuit to liberate more value, and the fine material is directed to the waste settling pond. The spiral classifier is also useful as a simple dewatering device when water is in short supply.
