A grinding roll for use in a material bed roll mill for the comminution of brittle material has a cylindrical body in the periphery of which are alternating grooves and lands. To the exterior of each land is secured a wear strip. The grooves of the confronting rolls may be directly opposite one another or the grooves may be offset axially so that the grooves in one roll confront a land of the opposite roll.
