The present invention relates to an apparatus for separating dry fine particles. To this end, the apparatus for separating dry fine particles according to the present invention comprises: a fine particle outlet disposed at one side of the upper part of a separation body; a stone powder supplier disposed at the other side of the upper part of the separation body; a fine particle separator having an air supplier at the lower part of the stone powder supplier; and an aggregate outlet disposed at the lower part of the fine particle separator, wherein the fine particle separator has a through-hole and a step-shaped structure formed by repeatedly connecting both ends of unit separation members, each of which is composed of a vertical member and an inclined member inclinedly bent from the lower end of the vertical member between separation frames inclinedly spaced apart from each other at a predetermined interval, wherein the upper end of the vertical member is spaced apart from the lower end of the inclined member to form a gap so that an air flow path is formed. Accordingly, frictional force generated during a period of removing foreign substances included in stone powder is prevented to further extend life span and save operation costs. |
