Method and device for two-stage classification of granular material |
摘要 |
Two-stage classification of a granular material, in particular a cement grinding feed, is accomplished in two classifiers connected in series in such a way that the separative behavior or the separative action and thus the particle-size distribution of the undersized or finished material coming from the second classifier can be modified with simple resources. Part or all of the oversized material of the second classifier is recycled to the second classifier.
