Abstract

In order to construct rollers (10, 11) for roller machines, in particular anti-wear armoured rollers for high-pressure roller presses for material bed crushing of granular material, in such a way that when operating the roller machine a recess-shaped or trough-shaped wear profile (15, 16) or lateral beads do not occur at the front-side ends of the roller surfaces, or only occur after a very long operating time, it is proposed according to the invention to construct the roller surface, which is per se wear-resistant, at its lateral edge regions (17, 18) in terms of wear technology in such a way that the lateral edge regions of the wear-resistant roller surface wear more rapidly in a selective manner, and this higher degree of wear counteracts the occurrence of the lateral beads on the roller surface or is counteracted by a matched roller geometry of the bead formation. <IMAGE>
