Abstract
Official abstract text for this publication.
The grinding roller of a roller mill according to the invention consists essentially of a roller shaft, a main roller body and an external wear ring having a wear protection, wherein the connection between the roller shaft and the main roller body is formed by a shrink fit. The main roller body is formed by at least two coaxially arranged intermediate rings.
First claim
Opening claim text (preview).
The invention claimed is: 1. Grinding roller of a roller mill, having a roller shaft, a main roller body, and an outer wear ring having wear protection, the connection between the roller shaft and the main roller body being formed by a shrink fit, characterised in that the main roller body is formed by at least 3 coaxially arranged intermediate rings. 2. Grinding roller according to claim 1 , characterised in that the connections between the intermediate rings and the wear ring are likewise formed by a shrink fit. 3. Grinding roller according to claim 2 , characterised in that the shrink fit is in conical or cylindrical form. 4. Grinding roller according to claim 1 , characterised in that the diameter of the grinding roller is at least 3.00 m. 5. Grinding roller according to claim 1 , characterised in that the diameter of the grinding roller is at least 4.50 m and the width is at least 2.00 m. 6. Grinding roller according to claim 1 , characterised in that the wear protection is formed by shaped bodies which protrude from the surface of the wear ring and/or by a hard build-up weld. 7. Roller mill for the comminution of brittle grinding stock, having two grinding rollers according to claim 1 , wherein the two grinding rollers are driven in opposite directions. 8. Roller mill according to claim 7 , characterised in that the roller mill is formed by a high-pressure roller mill which comprises a force application system that is in operative connection with at least one grinding roller for generating a grinding pressure of at least 50 MPa. 9. Roller mill according to claim 8 , characterised in that the roller shafts of the grinding rollers are mounted in slide bearings.
