Spiral classifier scope: 

 Spiral classifier classified according to the number of single-screw, double two types, according to the helical blade immersed in different degrees of spillway weir and sank into high-style two types, high weir overflow size for the 0.83-range -0.15mm mine grade, degree of sinking-type range for overflow 0.15 - 0.07mm grade ore. The spiral classifier widely used in mineral processing plant in the closed loop process with the ball dubbed triage ore sub-processes, or in a gravity concentrator to grade ores and off in the mud, and metal beneficiation process granularity of sub-slurry level, and washing off the job in the mud, dehydration and other operations. The spiral classifier has a simple structure, reliable and convenient operation. 

 Spiral classifier works: 

 Spiral classifier is by means of solid particles of different sizes, the proportion of different, so different in the liquid in the settling velocity principle, fine mineral particles floating in the water into the overflow out of crude mineral particles sink to bottom. Discharged by the screw into the upper part, to a hierarchical classification of mechanical equipment, the mill can grind the material powder level in the filter, and then use coarse material into the helical screw rotary vane mill sheet material inlet to filter out the fine material discharged from the overflow pipe. The machine base is made of channel steel, welded steel plate body. Screw axis into the head, shaft, using cast iron sleeve, wear durability, electric and manual lifting devices are two points. 

 Spiral classifier structure: 

 Spiral classifier mainly by transmission, spiral, trough, lifting bodies, the lower bearing (bearing) and of discharge valve.
