摘要

A grinding roller for the high-pressure comminution of granular milling material, having a reinforcement with hard bodies which protrude from the surface of the main part of the grinding roller. At least some of the hard bodies have a continuous recess, wherein the recess extends in the radial direction of the grinding roller. Refurbishing the surface of the grinding roller is substantially simplified by the continuous recess.
