Abstract
A classifying wheel for a centrifugal-wheel air classifier, through which the classifying air flows from outside to the inside against its centrifugal action. The wheel has blades arranged in a ring extending parallel to the axis of rotation of the wheel. The blades are positioned between a circular disc carrying the classifying wheel hub and an annular cover disc. The classifying wheel is entirely made in one piece and of a wear-resistant sintered material. The flow channels of the classifying wheel are formed by the surfaces of the classifying wheel blades extending parallel to each other and in direction of the axis of rotation of the wheel.
