The document discusses spiral classifiers, which are used in mineral processing to separate ore slurries by particle size. It outlines several key variables that must be balanced for effective classification, including the angle of the inclined bed, speed of the rakes or spirals, slurry density, tonnage throughput, and ore settling rate.

Spiral classifier achieves the purpose of classification based on the differing of solid particles in specific gravities. Spiral classifiers mainly include four types. They are high weir type single spiral classifier, high weir type double spiral classifier, immersed type single spiral classifier and immerse type double spiral classifier. ...

Common spiral classifiers can be classified according to the overflow height, that is, the position of the spiral in the water tank is different from the height of the pulp surface. The spiral classifier can be divided into three types: high dam type, low dam type and submerged type. 1). High Dam Spiral Classifier

Spiral Classifier Working Principle. When a spiral is working, the spiral sand washer needs to adopt an inclination of 15 ° tilt. Under the water tub, 3 weir plates form the sediment pool. The spiral head is immersed in this pool, and the spiral is driven by an electric motor through reducer rotating continuously. The freshwater is fed from ...

1. 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 development of spiral circuit …

Working Principle. The motion of the spiral creates pool hindered settling in the bottom pool area, and the agitation of water keeps the fines suspending in the liquid, while the coarser particles settle on the spiral and be transported to the discharge which located at the top of the classifier. Then gravity flow or pumps are used to move the coarse material to the next stage in the …

The spiral classifier was originally developed for closed circuit grinding It has since been applied very successfully to other classification duties where a two-product size split is required. Inherent operational qualities of this classifier make it ideally suited for sizing, washing, or dewatering materials such as ores, phosphate rock, sands, coal, oyster shells, solar and potash salts.
