  • Publication number: 20180071743
    Abstract: A wear-resistant body for crushing particulate material in the cement or mineral industries includes a body (1) provided with a plurality of highly wear-resistant inserts (3) embedded in complementary recesses (2) provided in the surface region (6) of the body. A ductile attachment part (4) is arranged within each recess (2), the ductile attachment part (4) being deformable by elastic or plastic deformation and the highly wear-resistant insert (3) being secured in the recess (2) by the ductile attachment part (4) after deformation. In some embodiments the ductile attachment part (4) is in the form of a ring or sleeve. A method for producing such a wear-resistant body is also provided.

  • Publication number: 20170348694
    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) having an axial extension in an axial direction of the roller and a radial extension in a radial direction of the roller, the wear surface (3) comprising a primary fraction of matrix material and a secondary fraction of hard phase material suspended in the matrix material, wherein the secondary fraction of hard phase material in a central portion of the wear surface is higher than the secondary fraction of hard phase material in a peripheral portion of the wear surface seen in the axial direction of the roller. Also the invention relates to a method of forming such a wear surface on a roller body.

  • Patent number: 9815119
    Abstract: Described is a wear-resistant roller component for handling abrasive materials where the component comprises a metal body with at least one surface. It is characterized in that a metal template having a pattern of through-going holes is arranged on the at least one surface of the metal body and in that a cover arranged to cover at least a part of the metal template is located at a distance from the metal template to form a gap between the cover and the metal template and in that a powder material suitable for sintering is introduced into the through-going holes in the metal template through the gap and in that the metal body, the metal template, the cover and the material powder are bonded together by means of a sintering process.

  • Publication number: 20130023393
    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).
