Spiral Classifier

Spiral-Classifier
Structure
Classifier mainly by transmission, spirochetes, tank, lifting mechanism, the lower seat (bush) and of discharge valve.
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. Feature
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.
