Abstract: A roller for use in devices configured to comminute material has a wear surface. The wear surface comprises inserts that are spaced apart differently to provide a desired wear characteristic in the wear surface. In one embodiment, some inserts may also have diameters or widths that are smaller than other inserts. For example, columns of inserts adjacent an end of the roller may have diameters that are smaller or larger than inserts in columns located near the center of the roller or otherwise positioned between the two ends of the roller. As another example, a middle portion of the wear surface may have inserts that include inserts of a larger or smaller diameter than inserts adjacent the ends of the wear surface.
