Spiral Classifier

Spiral classifier is one of beneficiation equipment, spiral classifier by means of different proportion of solid particles and thus precipitation in the liquid speed of different principles, mechanical An apparatus for grading. It can grind the material powder level in the mill filter, and then use the coarse material helix piece rotary vane screw mill feed port to filter out the fine material discharged from the overflow pipe. Spiral classifier called grader. Grader mainly high weir single spiral and double spiral, sank single spiral and double spiral classifier four kinds.

Spiral classifier has high weir single screw and twin screw, low weir type single screw and twin screw, sinking type single screw and double helix several classifier. Low Weir now use very little, mainly high weir and sinking and XL spiral classifier.

Spiral classifier is widely used in the concentrator and ball mill closed cycle process dubbed minute drive shunt mineral sands, or gravity concentrator to grade ore and fine mud, and metal beneficiation processes for pulp particle size grading and washing job off the mud, dehydration and other operations. The machine has a simple structure, reliable, easy to operate.

The machine base is made of channel steel body welded by steel plate. The head of the screw shaft, the shaft head, the use of cast iron sleeve, wear durability, improve device-electric and manual.

Spiral Classifier Working Principle

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

  • 1, for dry sand production process excessive powder separation, it can be very convenient control mechanism gravel powder content to meet user requirements.
  • 2, suitable for large dry, medium-sized sand making production line.
  • 3,0.00--0.75mm powder content of between 2% -15% adjustable.
  • 4, powder quality is easy to control, easy to adjust fineness, flexible and reliable.
  • 5, tile lining, repair rate is very low.
  • 6, variable frequency control technology, operating more concise.
