Spiral Classifier

Technical Process of Spiral Classifier

There are two types of spiral classifier, single spiral classifer and double spiral classifier. According to the spiral blade at the flooding end, there are two types: High weir type: the top side of spiral blade is higher than the flooding level and the center of blade is lower than the flooding level. This type is used for classification of the ore with flooding size between 0.083-0.15mm Immersed weir type: This type is used for classification of the ore with flooding size between 0.15-0.07mm. .
