Abstract

In order to improve the grinding and classification process, the subsequent dust separation, and to optimize the energy situation of a grinding plant, with the aid of a guiding apparatus and a displacement body, the fine material-fluid low leaving the dynamic classifier part with angular momentum, besides a swirl reduction or swirl elimination, is made uniform in a classifier outlet housing and deflected into a virtually linear flow. The fixed guiding apparatus arranged coaxially with the classifier axis in the classifier outlet housing and the displacement body can be formed as one unit and the guide elements of the guiding apparatus can be arranged on the displacement body and extending into the vicinity of the inner wall of the classifier outlet housing.
