A classification wheel for a centrifugal air classifier having an extension of a classification wheel vane in which the flow pattern of the classification air is opposite to the centrifugal force direction, that is, in the centripetal force direction, and which affects the flow pattern disposed in the flow channel is protected against wear It can be implemented in a protected design. This ensures that the classifying wheel has at least one reinforcing ring, the reinforcing ring has a hook evenly spaced around its outer periphery, and that the radially outer edge of the classifying wheel vane does not contact the reinforcing ring. The hook is achieved by gripping the classifying wheel vane at the extension.
