ABSTRACT:
The invention relates to a mill classifier or sifter, particularly a roller mill classifier, which is suitable as a high-performance classifier for a roller pan mill or a roller mill, e.g. for an air-swept mill. In order to achieve in the case of a particularly simple construction a high flexibility and optimization of the classifying processes as a function of the particular needs, there is a combination of a static distributor formed from several adjustable guide blade rings and a ledge rotor as the dynamic classifier. In order to achieve a multiple classifying and in particular a reduction of the coarse material fraction prior to dynamic classifying, in the vicinity of the static distributor is provided a deflecting device in an area of the classifier cover, through which the disadvantageous effects of a 90.degree. deflection are largely avoided.
