FW/HTS High Classifying Efficiency Air Classifier

Working Principle

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

Performance Features

1. Suitable fordry fine powder classifying, powders of ball shape, flake shape and needle shape, also powders with different densities.

2.Product size from classifier can vary from d97:2micron to 150micron. Theproduct size is adjustable, which makes the change of product size easy and simple.

3. Classifying efficiency (extraction rate) can be between 60% and 90%. Material with good flow-ability would have high classifying efficiency, otherwise, the classifying efficiency would be low.

4. Horizontal type of classifier wheelwould have high rotation speed andprecise top cut.

5. Several units of classifiers can be connected in series to produce several different sizes.

6. It can be connected with ball mill, vibration mill or Raymond mill to form a close-loop recycling system.

7. Control system has program control, can indicate real-time status, which make operate very convenient.

8. Negative-pressure system. Dust emission would be less than 40mg/m3. Our machines have noise isolation device, which makes noise not higher than 75dB(A).
