Abstract

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.
