Claim:
Method for reconditioning a used grinding roller of a material bed roller mill, containing a plurality of profile-members which are embedded, with a portion of the length thereof, in holes of the roller body and, with the remainder of the length thereof, projecting above the surface of the roller body, with that projecting portion of the profile-members and the surface of the roller body being at least partially worn, characterised by the following method steps: a) after the worn profile-members are removed, the worn surface of the roller body is turned at least in a part-region of the width of the roller body and differently worn part-regions are turned to different diameters; b) subsequently, material layers of different thicknesses are applied to the surface of those part-regions in a welding operation in order to obtain a uniform outer diameter; and c) subsequently, the welded material layers are provided with holes for receiving new profile-member.
