The MG12 spiral gave us the opportunity to achieve maximum recovery from a multi-stage circuit making the plant smaller and easier to float. The spiral bank modules dropped into and integrated with the plant structure enabling a smooth construction process. It proved to be a very effective solution for a new ore body."
The spiral classifier is characterized by simple structure, easy operation, large installation slope of the groove, easy configuration, and continuous discharge of sediment. However, often mixed with monomeric heavy minerals, the sediment needs to be returned to the mill for regrinding, which may cause overcrushing and reduce the efficiency of ...

The objective of this report is to understand the principles of classification, and the types of classifiers used in mineral processing. Discover the world's research 25+ million members
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 …
The spiral chute mainly uses the inertial centrifugal force generated by the minerals of different densities in the spiral rotation to achieve the separation of light and heavy minerals. Because of its simple equipment structure, low power consumption, and large processing capacity, it is widely used in the gravity separation process.

Common spiral classifiers include high type and submerged type. The high type is usually used for coarse-grain classification, and the diameter of the overflow particle size of the classification is generally greater …
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 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

The types of equipment that are used to accomplish this are called CLASSIFIERS. There are three basic kinds used. The first two, the RAKE classifier and the SPIRAL or screw classifier work on the same principal, and are not often used any more. These two types were popular for many years.
The Humphreys Spiral Concentrator is a simple, efficient gravity concentrator which effects a separation between minerals of the proper size range that have sufficient difference in their specific gravity. This concentrator is a spiral conduit of modified semi-circular cross-section, with outlets for removal of concentrate and middling.
