Spiral/Screw Classifier Speed. The speed of the conveyor should be just sufficient to handle the sands to be removed. The slower the speed the less the agitation in the pool and the finer the overflow. The lower the speed the longer the life of the classifier and all wearing parts. When and Where to use a Screw-Spiral Classifier
Spiral Classifier In mineral processing, the Akins AKA spiral or screw Classifier has been successfully used for so many years that most mill operators are familiar with its principle and operation. This classifier embodies the simplest design, smallest number of wearing parts, and an absence of surge in the overflow.
There are two types of spiral classifiers: mainly for ore grading with an overflow particle size of 25-120 mesh and 120-200 mesh.
The spiral classifier is a commonly used solid particle classification equipment to classify and separate materials according to particle size. It has a simple …
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
Spiral classifier achieves the purpose of classification based on the differing of solid particles in specific gravities. Spiral classifiers mainly include four types.
The key component of a spiral classifier is the main shaft, which is carefully designed and selected to prevent deflection due to the spiral weight and the thrust load imposed by the spiral during raking. Large diameter, seamless steel, tubular shaft with sufficient wall thickness are used for minimum deflection.
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 …

Spiral classifiers. A typical spiral classifier is shown in Fig. 1. The geometry of a spiral is characterized by the length or number of turns, the diameter, the pitch and the shape of the trough (Burt, 1984). The spiral feed is a mixture of water and ground particles that is gravity fed at the top of the spiral.

Spiral classifier is a common classification equipment used in mineral processing plants. It has the characteristics of simple structure, reliable operation, large processing capacity, stable classification area and high classification efficiency. Below we briefly introduce its importance, working principle, application and main classification.
Dewatering Spiral classifiers are designed to settle and dewater relatively coarse particles from high volume, low percent solid volume streams.
Traditional gravity classifiers that leverage differential settling velocities in the gravitational field are bulky and ineffective for particles less than 150 μ m.In this study, a newly introduced compact enhanced gravity Closed Spiral Classifier (CSC) is tested experimentally for the classification of slurries containing silica or iron ore fines.
