Spiral Classifier
A Spiral Classifier is a machine that is primarily used to classify the slimes (fines) from a coarser, sandy sized material. It has an inclined trough with one or two spirals revolving slowly and free from touching the sides or bottom of the tank. The motion of the spiral creates Pool Hindered Settling in the bottom pool area, where the ...

Common Types of Spiral Classifier Used in the Mineral Processing
Submerged spiral classifier. The overflow end of submerged spiral classifier is usually equipped with 4-5 spiral blades, all of which are immersed under the liquid level in the settling area, so the settling area of submerged spiral classifier is large and the classifying pool is deep.

Application of Spiral Classifiers in Mineral Processing
Tailings Processing: Spiral classifiers can also be utilized for tailings or residue processing, separating valuable minerals from them to reduce The selection of a spiral classifier depends on ...

Spiral Classifier | SpringerLink
Spiral classifier is used for material classification with spirals used to stir and convey materials according to the difference in material settling velocities. It is a kind of gravitational and hydraulic classifiers. The specification of spiral classifiers is represented by the number and diameter of spirals. The bottom of the classifier is ...

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.
