The roller mill according to the invention for milling brittle milling material (5) of different grain size has two milling rollers (1, 2), which form a milling gap (3) therebetween, and provides a delivery shaft (4) for feeding the milling material to the milling gap, wherein at least one distributing device (7) is provided in the delivery shaft, which distributing device is arranged above a center area (M) of the milling gap and extends across the milling gap perpendicularly to the longitudinal extension of the milling gap and covers 5 to 70% of the cross-section of the delivery shaft. During the milling of the brittle milling material, the milling material is delivered to the delivery shaft and milled in the milling gap, wherein the milling material is introduced into the delivery shaft or diverted in the delivery shaft in such a way that coarser milling material accumulates in a center area of the milling gap with respect to the longitudinal extension of the milling gap than in the in the edge areas. |
