Abstract: A description is given of a method for producing a wear-resistant roller for crushing of particulate material, such as crude ore for use in the mineral industry, by which method the surface region of the roller (1) is provided with a plurality of recesses (2) into each of which a wear-resistant component (3) is embedded. The method is characterized in that at least some of the material around each recess (2) is plastically deformed after the wear-resistant component (3) is placed in the recess and in that the deformed material changes the shape of the recess (2) and secures the wear-resistant component (3) to the roller (1).

Abstract: The invention relates to a wear-resistant roller (1) for crushing of particulate material, such as crude ore for use in the cement or minerals industry comprising a roller body (2), a wear surface (3) on the roller body (2). The wear surface (3) comprises welding beads (4) comprising a primary fraction of carbide material and a secondary fraction of material selected from the group consisting of Nickel, Nickel alloys, mixtures of Nickel and Nickel alloys and mixtures of Nickel containing refractory hard materials, Cobalt, Cobalt alloys, mixtures of Cobalt and Cobalt alloys and mixtures of Cobalt containing refractory hard materials. Furthermore, the welding beads (4) are welded to the roller body (2) in an overlapping manner such that two neighbouring welding beads (4) comprise an overlapping volume (5) and a non-overlapping volume (6), the overlapping volume (5) being an intersection volume between the two neighbouring overlapping welding beads (4), and the fraction of carbide material being higher in the overlapping volume (5) than in the non-overlapping volume (6) such that the overlapping volume (5) has a higher wear resistance compared to the non-overlapping volume (6) having a lower wear-resistance. Also the invention relates to a method of forming such a wear surface on a roller body (2).

Abstract: A description is given of a wear-resistant roller for crushing of particulate material, such as crude ore for use in the mineral industry, which wear-resistant roller comprises a plurality of grooves (5) in the crushing surface of the roller (2) and at least one element (6) of wear-resistant material placed in each groove (5), where the element(s) (6) of wear-resistant material is composed of a material which is harder than the material of the roller (2). The roller press is characterized in that welding material (7), introduced directly into each groove (5), surrounds and secures the element(s) (6) of wear-resistant material in each groove (5). In this way it will be relatively easy and fast to manufacture a wear-resistant roller and it will be possible to repair the roller at site as there are no particular demands to the precision of the grooves or the wear elements. Therefore ordinary hand tools can be used to repair the roller. Furthermore various shapes of wear resistant elements, also without any particular demands to precision, can be used as they to a certain degree are independent of the shape and form of the groove.
