In order to provide an improved pressing roller (1,2) which is capable of operating in an extremely high force nip environment with markedly reduced wear of the grinding surface, it is suggested that the a roll comprises an outer cylindrical pressing surface for use with an opposing roll, and a plurality of wear-resistant surface members (studs) (6), wherein the free ends of the studs protrude radially from the surface of the roll and spaces between the studs are filled with a matrix material and whereby the studs are fixed by welding to the roll, and the matrix material being softer than the hardest material of which the studs are made. |
