Abstract
An impeller shoe (110) having a front side (112) with a series of half column members (114) and raised upper and lower rims (116, 118) that form the impact surface of the impeller shoe. Half columns (114) and raised rims (116, 118) are formed with carbide material (120) formed therein in order to improve wear resistance at these critical surfaces.
Claims12
A wear-resistant, high-impact rock crusher member for use with an impact rock crusher having a turntable upon which a plurality of said rock crusher members are mounted to impact rocks moving generally radially on the turntable comprising:
- a member body cast from a white iron alloy and having a mounting structure formed for mounting said member body to the turntable and having a front wear side for impact with rocks to be crushed, said front wear side being formed with an elongated rib protruding therefrom, said rib being oriented transversely to radial movement of the rocks impacting said front wear side when said member body is mounted to the turntable by said mounting structure, and said rib being formed of a matrix of white iron alloy and carbide granules monolithically cast with a remainder of said member body.
A method of casting the wear-resistant, high-impact, rock crusher according to claim 12 having at least one wear surface, comprising the steps of:
- creating an impression in a mold that is compatible with an iron alloy material, the impression being formed in an area of the mold corresponding to the wear surface of the iron alloy member to be formed by the mold,
- positioning a quantity of carbide granules in the impression prior to pouring molten white iron into the mold;
- and
- pouring molten white iron alloy into the mold with the carbide granules in the impression, to cast the iron alloy member with a matrix of white iron alloy and the carbide granules formed in the impression area.
