Spiral Classifier

The spiral classifier efficiency we offer up to 90%, classification product size can reach D97: 3 ~ 150 microns and material replacement is convenient. It also can make classification of different density particles.
There are high weir single spiral and double spiral, sank single spiral and double spiral classifier several
Spiral classifier is widely used in the concentrator with the ball dubbed sub-Cheng Cheng closed cycle shunt mineral sands.
Concentrator to grade ore and fine clay, and metal beneficiation processes for pulp particle size classification, and wash off the mud in mining operations, dehydration and other operations. The machine has a simple structure, reliable, easy to operate.

Spiral Classifier Working Principle

Spiral classifier by means of different solid particle sizes, different specific gravity, thus settling velocity different principle in the liquid fine mineral particles floating in the water to overflow, coarse mineral particles sink to the bottom.
Discharged into the upper part of the spiral, to a hierarchical classification of mechanical equipment, the mill can grind the material powder level in the filter, and then use the coarse material piece rotary vane screw screwed into the mill feed, the filter out the fine material discharged from the overflow pipe.
The machine base is made of channel steel, steel plate welded body. The head of the screw shaft, the shaft head, using pig iron sleeve, wear durability, improve device-electric and manual.
