Abstract
The invention relates to a roller mill, particularly intended for dressing ores. To reduce the energy demand for comminution and classifying a grinding product, a classifying device is positioned below the grinding area and to it is supplied the comminuted ground material under gravity action, as well as classifying air from an annular chamber in the lower region of the grinding bowl and which has at least one fine material outlet and coarse material outlet.
