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
A friend familiar with this told me the main problem with spiral classifiers is the cut size is directly proportional to retention time (flow rate, Stoke's law, that sort of thing). To get a fine cut size requires flow of almost zero = the finer you want to cut, the lower the flow and density required. Hitzrot, H. W. wrote a great paper in Society for Mining, Metallurgy & …
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

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 classification equipment includes spiral classifiers and hydrocyclones. The 2 kinds of equipment have different classification effects because of their different structures and working principles. This article will introduce the working principle and characteristics of hydrocyclone and spiral classifier.
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.

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 ...
The spiral classifiers and rake classifiers are . mostly used in separating coarse particles from a . mixture. In case of fine separations, bowl . classifiers are employed.
Basically the different wet classifiers are g ravity settling tank, cone classifier, double cone class ifier, hydrocyclone classifier, spiral classifier, and rake classifier. 3.2 Gravity settling tank
Spiral classifiers, such as the Alpine Mikroplex design for separation in the superfine region, were developed to partially overcome undesirable boundary layer effects associated with spinning fluids at stationary walls (Rumpf and Leschonski (1967)). Air is introduced tangentially at the periphery into a flat cylindrical space and moves along ...
