Classifiers
Air classifiers separate materials by utilizing a dry process. Hydrocyclones, on the other hand, sort particles in a liquid suspension. Air classifiers can be used in aggregates production, manufacturing sand, industrial minerals production, as well as in mining operations. Hydrocyclones are most often utilized in mining applications.

Spiral Classifier Structure, Working Principle, Feature, …
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.

Types of Classifiers in Mineral Processing
In mineral processing, the Akins AKA spiral or screw Classifier has been successfully used for so many years that most mill operators are familiar with its principle and operation. This classifier embodies the simplest design, smallest number of wearing parts, and an absence of surge …
Gravity Spiral Concentrator Working Principle
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.

Gravity separation equipment | MD spirals
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."
OneMine | Application And Selection Of Spiral Classifiers
The spiral classifier was originally developed for closed circuit grinding It has since been applied very successfully to other classification duties where a two-product size split is required. Inherent operational qualities of this classifier make it ideally suited for sizing, washing, or dewatering materials such as ores, phosphate rock, sands, coal, oyster shells, solar and potash salts.

The spiral classifier is one of the important equipment in the mineral processing process. Its principle is to use the difference in the settling speed of solid particles in the liquid to classify materials.
Spiral Concentrator
During separation, the slurry enters the spiral through a feed box and then flows on to the spiral surface. As the slurry travels down the spiral, mineral grains settle and sort according to size, shape, and specific gravity. Spiral separation uses a flowing film principle based on the size and specific gravity difference present in a mineral ...
