The spiral classifier is also a mechanical classifier. It is made by combining a gravity settler of rectangular section with a sloped transport spiral for the sediment. It consists of a semi cylindrical trough (a trough which is semi-circular in cross- section) inclined to the horizontal. The spiral conveyor moves the solids which settle to the ...
1. The hopper + vibrating feeder (with grate) automatically feeds the material into the jaw crusher, and screens the 0-50mm material to the spiral washing machine. 2. The jaw crusher crushes 50-230mm iron ore into the fine jaw crusher. Spiral washing machine is suitable for cleaning 0-50mm materials. 3. The fine jaw crusher crushes the material ...
Common spiral classifiers include high weir type and submerged type. The high weir type is usually used for coarse-grain classification, and the diameter of the …
metals (PGMs) flotation tailings was carried out by means of spiral classifiers and a gravity separator (Knelson Concentrator KC-CVD – 6 unit). The economic mineral reserves for PGMs are found ...
The process is composed of two-stage circuit, the first stage is an open circuit of the first ball mill and spiral classifier, and the second stage is a closed circuit of the second ball mill and hydrocyclone. Particle size distributions of each streams were predicted through simulation, using the population balance (PBM), Stokes' and Plitt ...
It is widely used in minerals, metal powders, chemical raw materials, pigments, fillers, etc. Types: There are four classifiers: high …
A study was carried out to select the appropriate coatings for corrosion protection of the spiral classifier working at KGHM Polska Miedź S.A. Ore Concentration Plant. The abrasion resistance of selected protective coatings and wear-resistant linings was investigated using a DT-523 rotary abrasion tester with Taber CS-10 rubber abrasive …
Spiral classifier is suitable for the flow ore sand in the beneficiation plant, the particle size classification of the ore pulp in the metal beneficiation process, and the desliming and dewatering operations in the ore washing operation. It is especially suitable for washing, grading, impurity removal, and fine-grained and coarse-grained material …
Rake, spiral, and bowl classifiers use mechanical action to dewater, deslime or separate coarse bulk materials from finer materials or liquids. Drag classifiers consist of a chain-link conveyor or endless belt that is dragged through a solid-liquid mixture. Rake classifiers lift solid-liquid mixtures up onto a plate with a screen or rake.
Spiral concentrators (Fig. 5.2.3) are devices to separate different solid components in slurrybased upon a combination of the solid particle density, as well as the particle's hydrodynamic properties (e.g., drag).The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to extract solid …
1. The height of overflow dam. According to the height of overflow dam (the relative position of spiral in tank and slurry surface), spiral classifier can be divided into high dam spiral classifier, low dam …
Compared with these two classifiers, the hydrocyclone has a better classification effect when processing finer-grained materials (the separation particle size range is generally 0.3-0.01mm). 2. Floor area. Obviously, the footprint of the hydrocyclone is significantly smaller than that of the spiral classifier.
Rake Classifier. The Rake Classifier is designed for either open or closed circuit operation. It is made in two types, type "C" for light duty and type "D" for heavy duty. The mechanism and tank of both units are of sturdiest construction to meet the need for 24 hour a day service. Both type "C" and type "D" Rake Classifiers ...

Spiral Classifiers. The Akins, Hardinge, and Western Machinery are examples of the spiral. The first two consist of a spiral rotating in an open steel trough or box set on a slope, the spiral working the sand to the upper end and the slime overflowing at the lower end. Spirals of 8 to 12 inches diameter are available for small plants.
