Introduction of spiral classifier 
Scope: classifier classifier mainly has high weir type single spiral and double spiral, submerged four single spiral and double spiral classifier. The classifier is widely used in ball mill in the concentrator and the match into a closed cycle cheng cheng shunt mineral sand, or use to graded sand and fine mud in the gravity concentrator, metal beneficiation process for the pulp particle size classification, and the ore washing work of desliming, dehydration and other operations. The grading machine has simple structure, reliable work, convenient operation, etc. 
Classifier structure: classifier is mainly composed of transmission device, helix, tub, lifting mechanism, the lower bearing (bearing) and row ore valve. 
Classifier works: classifier is by means of solid grain size is different, the proportion of different, in the principle of velocity for different particles in the liquid sink on the bottom of the channel. Can through the spiral to the upper level of grinding mill in the powder on filtering fine particles floating in the water in the overflow, coarse ore for mechanical classification a classification equipment, and then the coarse material using spiral vane rotary screwing in mill inlet, to filter out the fine material discharge from the overflow pipe. The machine base with channel steel, the body USES the steel plate welded together. Screw shaft into the head, shaft head, pig iron, wear-resisting durable, electrical and manual lifting device is two.
