Claim:
A roller mill having a grinding table and at least one grinding roller rolling on the grinding table, grinding stock to be crushed being subjected to compaction in a gap formed between the grinding table and the grinding roller before being led off via the rim of the grinding table, and a fixed impounding edge that does not rotate together with the grinding table furthermore being provided, said edge being provided at least on the side of the grinding roller facing the rim of the grinding table and forming at least a part of an elevation of the rim of the grinding table, characterized in that the elevation of the rim of the grinding table is higher in the area of the grinding rollers than in the area between the grinding rollers and said impounding edge having an adjoining area arranged substantially parallel to a side face of said at least one grinding roller, in order to prevent the ground material escaping radially from the gap formed between the grinding table and the grinding roller and in order to discharge the finish-ground material only in an area between the at least one grinding roller that has just crushed the ground material and a next grinding roller.
