Introduction Of Spiral Classifier
![ico-1](https://i0.wp.com/www.yonghanmachinery.com/wp-content/uploads/2024/05/ico-1.jpg?fit=74%2C8&ssl=1)
Spiral classifiers can grade different particles in ore slurry during the metal beneficiation process as well as deslime and dehydrate in the washing operation.
They are widely used to separate ore sands by forming a closed-circuit with the ball mill in concentrators, or in gravity concentrators to classify ores and fine muds.
Applied fields of screw classifier
1.Superfine classifying of various powder materials; impurities removal; scattering.
2.Classify the superfine powder and nanometer powder with coarse particle; classify the viscous materials, with high adhesiveness, difficult to separate and low rate of mobility.

Applied materials: In the metal beneficiation process including gravity concentration and ore washing of the materials such as quartz, gold ore, iron ore, copper ore, ore, ore pulp, fine mud, cement clinker, magnetite, etc.
Working Principle of Spiral Classifier

The classifier is based on the principle that the solid particle size is different and the specific gravity is different, so the sedimentation velocity in the liquid is different. Fine ore spill out of the water, and the coarse ore particles will be sank to the bottom of the tank and finally pushed up by the screw.
