The invention relates to a grinding roll with pin-shaped profiled bodies embedded in the roll body, the roll body having a hardness of more than 56 HRc. This grinding roll is used in comminuting operation until a substantial proportion of all profiled bodies is completely worn and/or has fallen out of the roll body. For the repair of wear the roll surface is brought back to a cylindrical shape by partial removal of material, after which new recesses are produced and new profiled bodies are inserted. |
