description The invention relates to a method for comminuting material to be ground and to a roller mill and is suitable in particular for the extremely fine comminution of relatively hard and dry materials, for example cement clinker and blast furnace slag, and for relatively large roller mills. In order to avoid mill vibrations as a result of over-grinding the material to be ground and in order to reduce the specific work needed and also increase the throughput, a fine material nozzle (10) is arranged downstream of each grinding roll (4), wherein an air jet having a defined momentum is directed from said fine material nozzle from above onto a fine material concentration zone (12). The fine material concentration zone is formed immediately after the comminution zone of each grinding roll and is virtually free of material to be comminuted that has been fed in and accumulates in an edge region (13). The fine material blown out and up is supplied to a rising transport air stream and a following screening process.
