Classification in mineral processing is the operation of separating particle mixture components into two or more fractions according to size, with each resulting group more uniform in this property than the original mixture. There are two types of classifier:...
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, …
Spiral classifier achieves the purpose of classification based on the differing of solid particles in specific gravities. Spiral classifiers mainly include four types. They are high type single spiral classifier, high ... for the size grading of slurry in mineral processing plants and for desliming and dewatering
Dry mineral processing offers reduced mining water demand. It is considered to be economically viable due to lower capital and operational costs with a smaller plant footprint (Napier-Munn and Morrison, 2003).Franks et al. (2015) have reported that Dry Sand Fluidized Bed (DSFB) only in combination with heap leaching may have economic benefits with reduced …
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.

The spiral classifier is a commonly used equipment for mineral processing (sand washing). It is often paired with a ball mill to form a closed-circuit circulation to divert ore. It is also used in gravity concentrators to classify ore and fine mud, ore slurry in metal mineral processing processes, particle size classification, desliming, dehydration, and other operations in mineral washing ...
Hydrocyclones have become one of the most important and widely used classifiers in the mineral processing industry. They are also used for de-sliming, de-watering, de-gritting and thickening processes. They are most commonly employed in closed circuit within grinding circuits and are used to return coarse material back to the ball or rod mill ...
The Spiral Classifier is available with spiral diameters up to 120″.These classifiers are built in three models with , 125% and 150% spiral submergence with straight side tanks or modified flared or full flared tanks.

Design features of the commonly used classifiers such as the spiral, rake, cone, bowl are described. Descriptions and design of centrifugal classifiers, ...
In mineral processing operations, classification and separation of mixtures of fine and coarse particles and also of lighter and heavier particles may be performed in a wet or dry state. ... Classifiers with raised sides are generally called high or H-type classifiers. In contrast, classifiers with low sides and shallow tanks are known as S ...
The processing of heavy minerals and coal is often carried out using spiral classifiers. Processing of iron ore to separate coarse iron oxides such as hematite from light gangue mineral, such as quartz, is carried out in circuits with several hundreds of rougher, cleaner and re-cleaner spirals (Bazin et al., 2014).
Mineral processing involves separating valuable minerals from waste materials in mined ore. Among the wide array of equipment used in this process, the spiral classifier plays a pivotal role in ensuring the efficiency of beneficiation operations. It is a gravity-based classifier that separates particles by size and density.
The spiral classifier is widely used in the benefication plant to form a closed loop with the ball mill to split the ore, or to classify the ore and fine mud, grade the slurry during the spiral classifier mineral processing, and deslime and dewater in washing operations.

Working Principle. The motion of the spiral creates pool hindered settling in the bottom pool area, and the agitation of water keeps the fines suspending in the liquid, while the coarser particles settle on the spiral and be transported to the discharge which located at the top of the classifier. Then gravity flow or pumps are used to move the coarse material to the next stage in the …
