中文：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.
