    • The grinding roll according to the invention for a high-pressure roll mill has surface profiling having a multiplicity of wear-resistant profile bodies which are arranged at a distance from each other on the roll surface, wherein the surface profiling is provided both in a central region and in two adjacent edge regions of the grinding roll, so that autogenous wear protection is formed in the edge regions and in the central region. The number of profile bodies per unit surface area in the edge regions is greater than in the central region, and the free space between profile bodies in the edge regions is at least 15%, preferably more than 25%, less than the free space between the profile bodies in the central region.
    • 根据本发明的用于高压辊磨机研磨辊具有带有多个与间隔开的辊表面的表面轮廓,耐磨外形轮廓本体,与所述表面轮廓既在中央区域以及在研磨辊的两个相邻的边缘区域设置,以便在边缘区域和 在中部地区形成自生的磨损保护。 轮廓体的每单位面积在边缘区域的数目大于在中央区域和边缘区域的外形轮廓本体之间的自由空间大至少15%,优选超过25%,比在中央区域的外形轮廓本体之间的自由空间较小。
