AIR CLASSIFIER

Detailed Product Description

Work Principle:
The classifying device is composed of pneumatic classifier, cyclone collector, pulse collector, high-pressure induced draft fan, and control cabinet. The classifiers are equipped with second air inlet and vertical impeller rotor. The materials are fed into visa the bottom roller by force of induced draft fan and then mixed with first air to disperse particle and then brought to classifying zone. Owing to the high-speed rotary of classifying rotor, the particle is affected by the centrifugal force produced by the classifying rotor and centripetal force generated from induced draft fan. When the centrifugal force is stronger than the centripetal force, the coarse particle above classifying size fall down from inside roller, and is sieved by second air in the air inlet on the cone, then fine powder is separated from mixed coarse material. The separated coarse material is vented out from discharging device. The fine powder below classifying size flows into cyclone collector with air and solid flow, and then is collected by pulse collector. The purified air will be vented out from induced draft fan.
