China Air Separator Fine Powder Classifier

Air Separator Powder Classifier
Features and Advantages:
♦Available D50:1.5-25μm
♦Suitable for precise classifying of dry micron material,, can classify spherical, flaky, needle-like particles, and can also classify particles of different densities
♦Classifying efficiency (extraction ratio) can be 60%~90%.
♦The linear velocity of a horizontally installed classifying wheel is up to 80m/s.
♦Speed of wheel is controlled by inverter, particle size can be adjusted freely.
♦System equipped with muffler operating under negative pressure, meet environmental requirements,noise <76dB(A).
♦The classifying wheel can be made of ceramic materials such as alumina, zirconia and silicon carbide, without metal pollution, meeting the requirements of high-purity materials.
♦Grinding is in closed system, little dust, low noise in a clean and environmentally friendly process.
♦PLC control system, easy operation.
♦In conjunction with ball mill, table roller mill and Raymond mill to form closed circulation.
♦The motor can be connected with a belt, which is stable and reliable, realizes high speed and increases the speed, and breaks through the problem that the well-known motor brand does not have a high-speed motor.
♦Optional explosion-proof design, can also be upgraded to a nitrogen circulation system to meet the processing needs of flammable and explosive oxide materials.

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 for dry 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. The product 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 wheel would have high rotation speed and precise 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)
Applications
Widely used in chemical industry, mineral industry (especially good for calcium carbonate, kaolin, quartz, talc, mica and other nonmetallic product classifying), metallurgy industry, abrasive material industry, ceramics industry, fireresistance industry, pharmacy industry, pesticide industry, food industry, health care industry and new material industries.
