Spiral classifier and hydrocyclone are the main equipments for the classification operation of the concentrator. Although the rapid development of the cyclone once made the spiral classifier lose its market, but with the continuous changes in the requirements of the selection plant, it was found that the spiral classifier also has its advantages.
The spiral classifier is one of the equipment in mineral beneficiation plant. The spiral classifier is a kind of equipment for mechanical classification based on the principle that the specific gravity of solid particles is different, so the speed of precipitation in the liquid is different.
Mechanical centrifugal air classifiers are used extensively to process aggregates, ceramics, chemicals, foods, minerals, metals, plastics, flyash and other materials. Air classification of solid particles a review ...
