  • Patent number: 10159984
    Abstract: A method for making recesses in the surface of a roller for a rolling press. A thermal treatment is applied to a cylindrical roller surface by heating the surface in a region of the desired recesses until the material properties of the roller surface change permanently, i.e., even after cooling, with respect to the hardness of the roller material. The thermally treated regions produce a softer material in those regions than in the surrounding surface of the roller. By virture of a first start-up of the rolling press with abrasive material to be comminuted, the desired profiling is formed spontaneously due to a wearing down of the soft regions to form the desired recesses. The thermal treatment represent a particularly simple and cost-effective method for profiling rolling rollers, and in particular, rolling rollers which have already become worn, which that thereby be readily refurbished.
