 The classifying device is composed of pneumatic classifier, cycione, collector induced draft fan,control cabinet and so on,Equipped with second air iniet and vertical impeller rotro.the materials are fed in visa the bottom 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 classifying rotor and centripetal force generatde from induced draft fan.When the centrifugal force is strong than the centripetal force,the coarse particles fall down along inside roller.The second air is induced to sieve the coarse material is discharged from classifier,the over-milled powder are collected by the cyclone and pulse collector.

Technical Characteristics

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

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

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

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

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