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

Performance characteristics
- Can be used in series with multiple classifiers to obtain one or more narrow-size products at one time
- Compact structure, small occupation, lower investment cost.
- Suitable for classifying materials such as abrasives, soldering tin, foaming agent and carbon powder into particle size in narrow distribution.
- Suitable for precise classifying of dry micron material.
- The air screen type secondary air design has high energy utilization rate, promote material flow and dispersing, improves material flow the efficiency of powder selection.
- Classifying efficiency (extraction ratio) can be 60%～90%.
- System equipped with muffler operating under negative pressure, meet environmental requirements,noise <76dB(A).
- The inner lining is made of alumina, no metal pollution, meeting the requirements of high purity materials.
- Grinding is completed 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
Under the action of fan suction, the material is moved from the lower inlet of the classifier to the classifying zone with the ascending airflow. Under the strong centrifugal force generated by the high-speed rotating turbine, the materials are separated and the fine particles which meet size requirements through the classifier impeller gap into the cyclone separator or the dust collector, the coarse particles entrained part of the fine particles collided with the wall and the velocity disappeared, descending along the cylinder wall to the secondary air outlet, and the coarse and fine particles were separated by the strong washing action of the secondary air. The fine particles rise to the classification zone for secondary classifying, and the coarse particles are lowered to the discharge port for discharging.
