ABSTRACT:
The invention relates to a milling roller of a high-pressure material bed roller mill, having 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, protrude above the surface of the roller body, with, when the milling roller is new, the holes having different depths and the profile-members having different lengths in differently loaded part-regions of the width of the roller body. Such a construction brings about a long service-life for the roller and cost-effective reconditioning after operational wear with a production operation which reduces costs.
