Abstract
A grinding roll including a roll body having a cylindrical outer surface extending axially between a first end and a second end and a flange attached to at least one of the first and second ends. The flange includes an outer edge that extends radially past the cylindrical outer surface of the roll body. A first surface of the flange forms a perpendicular continuing surface with the cylindrical outer surface of the roll body. A second surface of the flange forms a continuation of one of the first and second ends of the roll body. The flange includes wear protection liner elements on the first surface. The first surface of the flange includes at least one lower part adjacent the cylindrical outer surface of the roll body and at least one upper part adjacent the outer edge of the flange. The lower part includes a first type of wear protection liner elements and the upper part includes a second type of wear protection liner elements. The average covering area of the second type of wear protection liner elements is larger than that of the first type of wear protection liner elements.
