Spiral Classifier
Spiral Classifier

Product introduction:Spiral classifier is commonly used in the grinding circuit of the beneficiation as the pre-classification and inspect classification machine and also in the ore washing and desliming operation. It is forms a closed cycle easily with the grinding machines with advantages of simple structure, reliable work and easy operation.

Technical Features
  • Simple Structure
  • Environmental Protection
  • Easy To Maintain
  • Optional Discharge Method
  • Large Processing Capacity
  • ● Simple structure, reliable running and easy operation.

  • ● It mechanically classifies through the mechanism of different sedimentation speed of the solid particle in liquid due to different size and different specific gravity.

  • ● It can classify the ground material powder from the grinder spiral the coarse grain into material inlet of grinder through the spiral chip and discharge the classified fine grain from overflow surface.

  • ● Its base is made from channel steel, while its body is weld from a steel plate.

  • ● The lower support of spiral bearing is of the engine-bearing structure of good wear-resistance and durability;
