Non-Metallic Mineral Industrial Micron Powder Air Classifier

The classification device is composed of pneumatic classifier , cyclone, collector , induced draft fan,conmtrol cabinet etc . Equiped with second air inlet and vertical impeller rotor ,the materials are fed in visa the bottem roller under the force generated from the induced draft fan and then mixed with first input air to disperse particle and then brought to classifying zone .
Owing to the high rotary speed of classifying rotor, the particles are under the centrifugal force produced by the rotor and centripetal force generated from induced draft fan . When the centrifugal force is stronger than then centripetal force , the coarse particles fall down along inside roller. the second air is induced to sieve the coarse materials and seperate the fine powder that stick on or mixed with coarse . after the coarse material is discharged from Classifier . the over -milled powder are collected by the cyclone and pulse collector .

 The QLFD classifier and the feeder, cyclone separator, Dust Collector , induced draft fan control system constitute a set of grading system. Under the action of negative pressure wind, the material directly enters the grading area from above the equipment through the feeder. Under the action of strong centrifugal force generated by the high-speed rotating grading turbine, the coarse and fine materials are separated, and the fine particles that meet the particle size requirements are collected by the cyclone separator or dust collector through the clearance of the grading wheel blade. The fine particles that meet the requirements of particle size enter the cyclone separator or dust collector through the clearance of the grading wheel blade. The coarse particles enter the secondary grading area through the fan and are graded for the third time under the action of the secondary wind. The material that meets the particle size enters the first-level grading area through the fan and is graded again. The material that meets the particle size requirements enters the cyclone collector or dust collector through the grading wheel blade, and the separated coarse particles are discharged through the unloading device.

Working Principle:
As a forced centrifugal classifier with secondary air entry and stand grading rotor, the classifier is composed of grading rotor, guide vane rectifier and screw feeder. The materials are fed through the upper cartridge and the grains will be sieved and well distributed by the incoming air, which brings the grain to the grading zone. The centrifugal force produced by the fast rotation of gather in the centripetal force by the pneumatic atheism act on the grading grains when the centrifugal force on the grain is greater than the centripetal force. The coarse grains above the grading range will be swirled down along the untrained wall, the second air will be rectified to uniform cockney through the guide wane and separate the thinner grains from the discharge port. The thinner grains below the grading range will be blasted to cyclone separator and collector whereas the purified air will be vented outside.(For details, please contact me:Annie Chang,Mob:0086-18678029069(whatsapp),E-mail: Annieflower.chang dot sdguote.com)

1.Higher Capacity
Special designed for coarse final product with higher capacity. Secondary air design improves the classifying efficiency.

2.Higher Hardness Material
Inside are easy for wear-resistant with kind of material, which can be suitable for material with higher hardness.

3.Higher Flexible Design
According to customers' workshop height, the motor driven way can be direct or belt. Inlet also can from top or from bottom.
