The main component of the spiral classifier is the spiral. According to its position in the tank and the level of the slurry surface, it can be divided into three types: low dam, high dam, and submerged spiral classifiers. The low dam spiral classifier is rarely used now; the high dam and submerged spiral classifiers are mainly used. 1.
