Spiral Classifiers and Cyclones
This work provides a comparison between the most commonly used classification equipment in the treatment of minerals - hydrocyclones and spiral classifiers - considering their applications and costs. Although in use for decades in the mining industry, spiral classifiers have lost a lot of their importance due to the development of cyclones. This trend, however, is now being reversed, …

What is Spiral Classifier in Mineral Processing?
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

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 uses the principle of the proportion different of solid particles, so the precipitation speeds is also different in the liquid. Fine mineral particles float in the water and overflow; the coarse ore particles settle on the bottom of the channel. Material is discharged from the upper by spiral, so as to finish the grading work.
