ROTATIONAL CLASSIFIER WITH A SLIDE

摘要

The present invention relates to a centrifugal classifier capable of improving a classification performance by installing an aperture control member controlling an aperture by hiding a lower portion of a side of a rotor which is an inlet of a fine powder discharge passage. The present invention comprises: a classification chamber having an inlet into which a fine particle is introduced formed on one side; a fine powder discharge pipe installed to be communicated with an upper side of the classification chamber; a coarse powder discharge pipe installed to be communicated with a lower portion of the classification chamber; the rotor installed to be rotated by a driving apparatus inside the classification chamber, having a plurality of blades for producing an air intaking force at regular intervals along a circumference direction, and classifying the fine particle introduced into the classification chamber into the fine powder and the coarse powder; and the aperture control member in the shape of a ring where an upper side and a lower side are open, installed to hide a lower portion of a side of the rotor in the lower portion of the classification chamber, and controlling the aperture of the side of the rotor where the fine powder is introduced.
