A particle classifier and in particular a particle classifier wheel where the blades are made entirely of a wear-resistant material such as sintered corundum. The blades extend between two discs and are mounted therebetween to have some axial play. The ends of the blades fit into annular grooves formed in the two discs and rubbery-elastic inserts are provided to hold the blades in place.

A rotating wheel for an air classifier through which air carried particles flow from outside said wheel to inside said wheel, comprising: (a) a plurality of blades made entirely of wear resistant ceramic in a crown arrangement running parallel to the axis of rotation of said wheel; (b) a first disc

A rotating wheel for an air classifier through which air carried particles flow from outside said wheel to inside said wheel, comprising: (a) a plurality of blades made entirely of wear resistant ceramic in a crown arrangement running parallel to the axis of rotation of said wheel; (b) a first disc at a first end of said blades carrying a hub for the classifier wheel; (c) a second disc defining a central opening for use as an annular shroud disc located at a second end of said blades; (d) distance bolts positioned between said first and second discs in order to maintain said first and second discs at a predetermined distance of separation; (e) recesses defined by said first and second shroud disc for receiving and holding opposite ends of said blades without exertion of substantial axial forces on the blades, axial play between said blades and said discs being provided; and (f) rubbery-elastic, wear resistant inserts disposed in said recesses to radially support said blades between said first and second disc.
