Spiral Classifier, Dewatering Screw. This spiral classifier/dewatering screw is a multi-purpose machine. As a classifier, it separates out the smaller waste particles from the ore processor tailings. The larger particles can then be returned to the grinding circuit for finer grinding to liberate more values.

 — Due to the long-term harsh working environment, the main shaft (hollow shaft) of the spiral classifier is prone to damage or breakage. This problem is not only a common failure of the spiral classifier, but also a major problem that is difficult to solve, which has a great impact on the normal operation of the spiral classifier. Solutions:

 — The spiral classifier is a commonly used equipment for mineral processing (sand washing). It is often paired with a ball mill to form a closed-circuit circulation to divert ore.

 — 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).

 — Slurry concentration, Ore feeding amount & Uniformity When the concentration of the slurry is constant, if the amount of ore fed into the classifier increases, the flow rate of the slurry will also increase, thus making the overflow product particle size coarser. As the ore volume decreases, the particle size of the overflow product becomes …

 — The smaller, faster ore will be able to travel a longer distance than the large particles before the rakes or spiral will pull the ground material back towards the coarse ore discharge. If the Classifier is able …

 — Spiral operation and partition curves of the particles. A spiral classifier is shown in Fig. 1. The spiral feed that consists of a water-slurry of ground ore enters the top of the spiral. As the slurry enters the spiral various forces (Burt, 1984) act on the particles to operate the separation between light, heavy, coarse and fine particles.

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.
