Abstract (en)
1. Roller mill, especially a flaking roller mill, for granular material, with at least two rollers (1, 2) which are held or pressed against one another by means of a pressure device, with a product feed system (4) via which the material is feedable at both sides beyond the axial ends of the rollers, also with product guides (9) arranged one each at the two sides of the axial ends of the rollers, opposite the end faces, and at least partly covering the region between the rollers, characterised in that the product guides are constructed each as return conduits (9; 109; 209) for the material supplied axially over the ends of the rollers (1, 2) into the roller gap (3) and, with a guide surface (13, 113; 213) in each case, discharge the material above the roller gap (3) which engages and compresses the granular material into the region between the rollers (1, 2).
