Abstract
A classifying wheel for a centrifugal-force air classifier where the flow pattern of the classifying air is contrary to its centrifugal direction, namely centripetal, and which is equipped with extensions fitted to the classifying wheel vanes within the flow channels which influence the flow pattern is to be executed in wear-protected design. This is achieved in that the classifying wheel has at least one reinforcing ring which has uniformly spaced hooks arranged around its periphery which fix the classifying wheel vanes to the extensions so that the outside radial edge of the classifying wheel vanes is not in contact with the reinforcing ring.
