Spiral Classifier Introduction: Spiral classifieris widely used for classifying materials in the mineral processing flow as well as the desliming and dehydrating in the mineral washing operating process. The spiral classifier generally forms a closed processing flow. Spiral classifier is mainly composed by transmission device, screw, cell, movable lift, lower seat (bush) and discharge valve. Spiral classifier is a kind of classifying machine that adopt the principle of settling speed difference according to different material sizes and specific gravity. Spiral classifier of Hongji Group is classified into two types: single spiral classifier and double spiral classifier. Features of spiral classifier: 1) Simple structure; 2) Convenient to operate; 3) High efficiency; 4) Low cost. Techincal Parameters of Spiral Classifier:
