A mill classifier, particularly a roller mill classifier, has a strip rotor and a concentrically arranged guide vane ring with flow-optimized guide vanes and flow channels for a parallel incoming and outgoing flow without constriction or with widening and a diffuser effect. The flow-optimized guide vanes with an incident flow tube with vertical rotation axis and at least one guide plate are arranged adjustably for a tangential to radial incident flow of the strip rotor.
