Vertical Air Classifier(Multiple Classify Wheel)

Air classifier works with cyclone separator, bag filter and suction fan to form a complete classifying system. Material would go from the bottom part of air classifier up to the classifying cham- ber by the air flow from suction fan. The classifier wheel with high-speed rotation would create a strong centrifugal force to separate coarse and fine powder. Qualified fine powder would go through the wheel vane then into the cyclone or bag filter, while coarse entraining fine powder would lose its speed and fall down along the wall of chamber to the inlet of secondary air. The secondary air flow would disperse it further and separates coarse and fine powder. Fine powder would go up to the classi- fying chamber for further classifying, while coarse powder would fall down and will be dischanged from the bottom outlet.

• Performance characteristics

  • Available D50:2-45μm.
  • Suitable for precise classifying of dry micron material.
  • Classifying efficiency (extraction ratio) can be 60%～90%.
  • The linear velocity of vertically installed classifying wheels is up to 70m/s.
  • Speed of wheel is controlled by inverter, particle size can be adjusted freely.
  • System equipped with muffler operating under negative pressure, meet environmental requirements,noise <76dB(A).
  • The inner lining is made of alumina, no metal pollution, meeting the requirements of high purity materials.
  • Grinding is in closed system, little dust, low noise in a clean and environmentally friendly process.
  • PLC control system, easy operation.
  • In conjunction with ball mill, table roller mill and Raymond mill to form closed circulation.
  • The motor can be connected with a belt, which is stable and reliable, realizes high speed and increases the speed, and breaks through the problem that the well-known motor brand does not have a high-speed motor.
  • Optional explosion-proof design, can also be upgraded to a nitrogen circulation system to meet the processing needs of flammable and explosive oxide materials.
