ABSTRACT:
The invention relates to a roll mill, particularly a material bed roller mill for the comminution of brittle material for grinding, with two grinding rolls which are driven so that they rotate in opposite directions and are pressed against one another at high pressure, each of these grinding rolls having a roll shell of wear-resistant chill cast material with a surface profile. So that the rolls have a particularly good nip capacity and a high wear resistance, profiles in the form of weld beads of wear-resistant deposit welding material are applied to the surface of the chill cast roll shell.
