Sprial classifier(Spiral separator)
Sprial classifier has four type,they are immerged single spiral classifiers and immerged double spiral classifiers, high weir spiral classifiers and submerged spiral classifiers.
If the overflow edge is higher than the center line of spiral shaft and lower than the external diameter of spiral at the overflow end, the spiral classifiers are high weir ones. If the overflow edge is higher than the center line of spiral shaft and also higher than the external diameter of spiral at the overflow end, the spiral classifiers are submerged ones.
High weir classifiers are usually used for the classification with particle size of below 100 meshes. Submerged classifiers are usually used for the classification with particle size of below 200 meshes.
