GF Pneumatic Air Classification Series for Fine Powder Separation and Sand Classifier

1. Applications of Air Classifiers:  

Series GF Air Classifier (Series GF Pneumatic 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 .

 2. Work 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.

3.Technical Parameter

4. Technical Features:

1,The classifier used within the ceramic protection, less equipment wear,no pollution,high purity.

2,classifier structure is designed,almost by all large particles, high grading precision,large granular control.

3,classification by grading impeller speed and fan free to adjust the air volume, in order to obtain the required product, grading range.

4,adopts low speed vertical single impeller hierarchical structure , material flow is stable, equipment processing capacity,high classification effciency.

5,using multi-stage structure,at the same time granularity classification of several products,the particle size distribution to obtain the ideal.
