Spiral classifier is widely used in mineral processing plant to form closed cycle way with ball mill for split mineral sand, or used in gravity concentrator to grade ore and fine mud ...

The spiral classifier such as the Akins classifier consists of a semi-cylindrical trough (a trough that is semicircular in cross-section) …

Classifier. The Spiral Classifier used for the study was manufactured by Nick and Paul. 2.2 Designing of Test Works Prior to test work design, visit to the oxide plant at Ghana Manganese Company (GMC) were made with the aim of getting acclimatize with the current operations at the plant. The Spiral classifier was operated in batch mode.

Spiral classifier can be divided into two types, namely high type and submerged type.The particle size of materials for different types of sorting is different. Among them, the high type is mainly for coarse particle sorting, and its sorting overflow particle size diameter is generally greater than 0.15mm; while the submerged type is …

The size recovery curves of minerals in mineral processing equipment provide an efficient way to analyse the operation of spiral concentrators. However unlike other gravity concentrator equipment such as hydrocyclones or hydraulic classifiers a drop of recovery in the region of coarse particles is observed for spirals.

A spiral classifier is a mineral processing equipment which receives an ore slurry input and performs a gravity separation process between the solids particles of ore and the …

(1) The spiral blades at the lower end of the submerged spiral classifier are all immersed in the pulp with the largest classification area, which is applicable to the processing of fine materials. (2) The spiral blades at the lower end of the high- spiral classifier are partially immersed in the pulp with smaller classification area. The ...

For processing of sand minerals normally spirals are being used at onshore where the bottom or base of the plant remain stable and, the heavy minerals (grains with specific gravity generally greater than about 2.9) migrate to the inside of the spiral while the lighter materials (shell, quartz, phosphate, etc.) will be carried in the water stream toward the …

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, …

Introduction. 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).

Traditional gravity classifiers that leverage differential settling velocities in the gravitational field are bulky and ineffective for particles less than 150 μ m.In this study, a newly introduced compact enhanced gravity Closed Spiral Classifier (CSC) is tested experimentally for the classification of slurries containing silica or iron ore fines.

Spiral Classifier has been widely use in closed-circuit grinding operations and it can also be used for the classification of ore sand and slime in gravity beneficiation plants, for the size grading of slurry in mineral processing plants and for desliming and dewatering

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 …
