Method for classifying a ground material-fluid mixture and mill classifier

摘要

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.

1. Method for classifying a ground material-fluid mixture, produced in a roller grinding mill, comprising:
supplying the ground material-fluid mixture to a classifier having a dynamic classifier part with an outlet cross-section, separating coarse material from fine material in the dynamic classifier part, discharging the fine material in a fine material-fluid flow, wherein the fine material-fluid flow leaving the dynamic classifier part with an angular momentum is fed to a classifier outlet housing positioned above the outlet cross-section of the dynamic classifier part and wherein the fine material-fluid flow is made uniform and subjected to a swirl elimination and additionally exposed to a displacement body in the classifier outlet housing before the classifier outlet.
