Spiral Classifier

Spiral classifier is one important classification equipment in ore dressing industry.Combined with more than 30 years of production experience,SBM develop the new generation of spiral classifier,with the world-class technology.This is a mechanical extension equipment,which follow the principle that,different proportion of solid particles have a different sinking speed in the liquid.
SBM Spiral classifier has the feature of simple structure,reliable work,convenient operation,which to a large extent reduces your equipment investment cost.Moreover,its adaptability is very good and it can work in combination with the mill and flotation machine,to achieve the best separation results.

Application of Spiral Classifier

SBM Spiral Classifier is applicable to classify any of the pulp with mechanical method.At present,SBM spiral classifier has shown a remarkable performance in ore dressing,metallurgy,chemical,electric power,cement and many other industries.

  • In the concentrator,it can match with ball mill and form a closed cycle for the graded of mineral sand.
  • In the gravity concentrator,it can grading ore and fine clay.
  • For metal beneficiation process,it can carry a classification by the pulp particle size and accomplish desliming and dehydration.

Distinctive feature of Spiral Classifier

  • Simple structure and convenient to operate.
  • More suitable for dealing with the materials with smaller particle size and fine clay.
  • The quality of final material easy to control.fineness adjustment is convenient, flexible and reliable.
  • Uses the frequency conversion control technology and simple to operate.
  • Adoped tile lining and repair rate is very low.
  • Mixing plant restore the fine ore grain to the pulp surface,improving the quality of separation.
  • With double ore dischange,avoiding the reverse flow of pulp and improving efficiency.

Working principle of Spiral Classifier

SBM Spiral Classifier consists of driving device,spiral body,body,lifting mechanism,lower bearing and discharge valve.It depends on different deposition speed of solid particle due to their size difference and weight difference.Thin mineral particle can float in the water and flow out, and the coarse mineral particle will deposit into the bottom of the cell, which is pushed up by screw and discharged.
