Abstract
The invention relates to a dynamic roller mill air classifier, which is provided in integrated manner over a roller mill. As existing air classifiers suffered from certain disadvantages with respect to the specific energy requirement, the invention makes it possible to reduce the latter. The air classifier is designed as a downflow classifier, which classifies in an efficient manner with reduced flow rates.
