The mill and classifier are a correlated set. The effect of classifier has impact on the efficiency of mill. So it is a key point in the mineral separation process to select well the classifying equipment. The spiral classifier can be divided into the single spiral classifier and double spiral classifier according to the spiral axle quantity. It is divided into the high weir type, the low weir type, and the sinking type according to the overflow weir height. This instruction is only for the low weir type and the sinking type. The overflow position of high weir type of spiral classifier is above the center of the lower spiral axle but below the upper part of the overflow spire. It has certain falling area, applicable for classifying rough granules to obtain an overflowing force more than 100mesh. The whole screw of the sinking type of spiral classifier at the overflow end sinks below the liquid surface of the falling section which has a large area and depth. So it is applicable for classifying fine granules to attain an overflow granularity of less than 100mesh.
