ABSTRACT:
A gas stream classifier has a gas stream classifying means for classifying a feed powder supplied from a feed supply nozzle, into at least a coarse powder fraction, a median powder fraction and a fine powder fraction by an inertia force acting on particles and a centrifugal force acting on a curved gas stream due to Coanda effect in a classification zone, wherein the classification zone is defined by at least a Coanda block and a plurality of classifying edges, the feed supply nozzle is attached at the top of the gas stream classifier, the Coanda block is attached on one side of the feed supply nozzle, and the feed supply nozzle has at its rear end a feed powder intake portion for supplying the feed powder, and a high-pressure air intake portion.
