Title: Mill classifier
Inventor: BRUNDIEK HORST
IPC: B07B7/083
Filed: 1995-07-05
Abstract: A mill classifier or sifter is suitable as a high-performance classifier for a roller pan mill or a roller mill, for example, in an air-swept mill. In order to achieve a high flexibility and optimization of the classifying processes as a function of the particular needs utilizing a particularly simple construction, there is combined a ledge rotor as a dynamic classifier and a static distributor formed from severaladjustable guide blade rings. In order to achieve multiple classifying, in particular a reduction of the coarse material fraction prior to dynamic classifying, a deflecting device is provided in the vicinity of the static distributor in an area of the classifier cover. This arrangement largely avoids the disadvantageous effects of a 90° deflection.
