7. WET CLASSIFICATION Wet classifiers are based on the principle that separation of coarse particles from fine particles by water or any other liquid. In wet classifiers coarse particles move faster than fine particles at equal density. High density particles move faster than low density particles at equal size. Industrial classification may be carried out in different types …

Classification

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 ...

Spiral Classifier

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 ...

Principles of Spiral Gravity Classification

if the cylinder diameter is 100mm, the formed spiral diameter is 500mm and a 45˚ inner slope is involved then the downward slope of the outer edge would be 11.3˚ (see fig.4, yellow angle). The formed spiral would also slope inwards towards the supporting cylinder. This is the important angle β of fig.1 and is given by: tanβ = 2(D2-D1) (5 ...

Spiral Classifier for Mineral Processing

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 trough is provided with a slow-rotating spiral conveyor and a liquid overflow at the lower end.

Spiral Classifier Definition

the spiral classifier were critically observed and studied to understand spiral classifier operation. The adjustable parameters at the classifier section were the feed particle size, amount of water supplied to the classifier, angle of inclination of the classifier, feed tonnage, the speed of the spirals and the washing time.
