A grinding roll and a grinding assembly comprising the grinding roll

Abstract

A grinding roll (100) is disclosed. The grinding roll comprises a roll body (102) having a cylindrical outer surface extending axially between a first end (108) and a second end (110) of the roll body (102); a flange (112) attached to at least one of the first and second end of the roll body (102), the flange (112) having an outer edge (114) that extends radially past the cylindrical outer surface of the roll body (102), the flange (112) having a first surface (116) and a second surface (208), the first surface (116) forming a perpendicular continuing surface with the cylindrical outer surface of the roll body (102), and the second surface (208) forms a continuation of the at least one of the first and second end (108, 110) of the roll body (102); the flange (112) comprises wear protection liner elements on the first surface (116). According to the disclosure the first surface comprising at least one radially lower part (118) adjacent the cylindrical outer surface of the roll body (102), and at least one radially upper part (120) adjacent the outer edge (114) of the flange (112), wherein the at least one radially lower part (118) comprises a first type of wear protection liner elements (122) and the at least one radially upper part (120) comprises a second type of wear protection liner elements (124), and wherein an average covering area of the second type of wear protection liner elements (124) is larger than that of the first type of wear protection liner elements (122).
