Abstract:
1. A mill classifier for classifying a ground material-fluid mixture, comprising: a dynamic classifier part having an outlet cross-section, a guide vane ring having guide vanes and surrounding the dynamic classifier part at least in areas, a classification chamber formed between the dynamic classifier part and the guide vane ring, a coarse material removal, at least one discharge opening for the fine material-fluid flow, a classifier outlet housing arranged in relation to the flow direction after the dynamic classifier part and above the outlet cross-section, and a guiding apparatus and a displacement body disposed in the classifier outlet housing as a device for uniformisation and swirl elimination of the fine material-fluid flow leaving the dynamic classifier part with an angular momentum, wherein the discharge opening for a homogenized, linear fine material-fluid flow is arranged spaced apart from the guiding apparatus in an upper region of the classifier outlet housing, and wherein the displacement body has the form of a double cone in its vertical section and includes a lower conical region which extends into the dynamic classifier part.
