Abstract
A disc and spacer for transporting materials on a roller screen. The disc includes a circular main body and a wear resistant portion. The circular main body has a centrally arranged opening, through which opening a centrally arranged imaginary axis extends. The wear resistant portion is arranged around the circular main body and includes a plurality of protuberances that are circumferentially arranged along the periphery of the wear resistant portion and which, project radially outward from the main body. The wear resistant portion has a first material and the main body has a second material, the first and second materials having different wear resistant properties.
Claims17
A disc arranged for cooperating with a spacer for transporting materials on a roller screen, the disc comprising:
- a circular main body having a centrally arranged opening, through which opening a centrally arranged axis extends;
- and
- a wear resistant portion arranged around the circular main body, wherein the wear resistant portion includes a plurality of protuberances circumferentially arranged along a periphery of the wear resistant portion, the plurality of protuberances projecting radially outward from the main body, wherein the wear resistant portion includes a first material and the main body includes a second material, the first and second materials having different wear resistant properties, wherein the wear resistance of the first material is greater than the wear resistance of the second material, wherein the first material is bonded with the second material so that the wear resistant portion and the main body are integrated, and wherein the second material includes a matrix material, and the first material includes cemented carbides metallurgically bonded to the matrix material.
A spacer arranged for cooperating with a disc including a first material and a second material, and for transporting materials on a roller screen, the spacer comprising:
- a cylindrical main body having a first axial end, a second axial end, an outer surface and a centrally arranged passage, through which passage a centrally arranged axis extends;
- and
- at least one ridge extending axially and/or radially on the outer surface of the main body, wherein the at least one ridge includes a third material, the main body including the third material and/or a fourth material, the third and fourth materials having different wear resistant properties, wherein the wear resistance of the third material is greater than the wear resistance of the fourth material, wherein the third material is bonded with the fourth material so that the main body and the at least one ridge are integrated, and wherein the fourth material includes a matrix material, and the third material includes cemented carbides that are metallurgically bonded to the matrix material.
