Air Classifier

Under the action of the fan, the material moves to the classification area at a high speed from the lower inlet of the classifier with the updraft. Under the action of the strong centrifugal force generated by the high-speed rotating classification turbine, the material is separated, and the fine particles meeting the particle size requirements enter the cyclone separator or dust collector through the blade gap of the classification wheel for collection. The velocity of some fine particles entrained by coarse particles disappears after hitting the wall, and then decreases to the secondary air outlet along the wall of the cylinder. Through the strong washing effect of the secondary air, the coarse and fine particles are separated, the fine particles rise to the secondary classification in the classification area, and the coarse particles drop to the discharge port for discharge.
