Mineral Processing Spiral Classifier

Mineral Processing Spiral Classifier

Mineral Processing Spiral Classifier

Mineral processing spiral classifier, also called screw classifier, is widely used for distributing ore in the close circuit with ball mill, grading ore and fine slit in the gravity mill, grading granularity in the flow of metal ore-dressing and de-s and dehydrating in the washing.

According to the principle that different grains are with different specific gravity and sedimentation rate in the liquid, the fine ore flows in the water and the coarse ore sinks in the bottom. The mineral processing spiral classifier that has machine grading by discharging from the top can filtrate the materials and send coarse materials to the feeding mouth and discharge the fine material from the pipe.

Two Types Of mineral processing spiral classifier

According to the spiral blade at the flooding end, there are two types spiral classifier-high weir type and immersed weir type.

  1. High weir type: the top side of spiral blade is higher than the flooding level and the center of the blade is lower than the flooding level. This type is used for classification of ore with flooding size between 0.83-0.15.
  2. Immersed weir type: the whole spiral blade is immersed in the flooding level of the flooding end. The type is used for classification of ore with flooding size between 0.15-0.07mm.

mineral processing spiral classifier Appliciation

Our spiral classifiers are widely used in the distribution of ore in closed circuits with ball mills, grading ore and fine slit in gravity mills, grading granularity and flow of metal ore-dressing, and de-sliming and dehydrating in washing.

Spiral Classifier Benefits

  1. Simple structure and easy to maintain
  2. Easy operation and stable performance
  3. Large volume with buffering and conveying effect, better for grinding work.
  4. Gravity connection with Ball mills,slurry pump conveying is not necessary.
