<p>The present invention relates to a two-staged vertical centrifugal classifier, which additionally crushes powders of raw materials and efficiently classifies raw materials into fine powders and thick powders, comprising an upper rotor which is penetrated into an upper part of a casing and is accordingly installed, and rotates air used for classification and accordingly lifts classified fine powders; a lower rotor which is installed at the lower part of the upper rotor in the casing with use of the concentric upper rotor; a raw material supplying chute which is installed on the upper part of the casing to supply the powder of raw materials to the upper part on a dispersing plate on the lower rotor; a classification room which is installed between the upper rotor and the lower rotor in the casing; a cyclone which is installed in the casing to enable a guide vain of the lower rotor to be inserted and to supply air used for classification to the classification room; a fine discharging hole which discharges classified fine powders out of the classifier; and a thicker discharging hole which discharges classified thick powders out of the classifier.</p> |
