<p>The invention relates to a grinding roller (1) for the high-pressure comminution of granular milling material (40), having a reinforcement with hard bodies (10) which protrude from the surface (5) of the main part of the grinding roller (1). According to the invention, at least one part of the hard bodies (10) has a continuous recess (20), wherein the recess (20) extends in a radial direction of the grinding roller (1). Replacing the surface (5) of the grinding roller (1) is substantially simplified by the continuous recess (20).</p> |
