Choices for mining wear parts and excavating wear parts cover dump blocks, excavator bucket protection, feeder deck plates, ferrule dump sockets, ground engaging tools (GET), gyratory and jaw crusher liners, hoist chain, loader bucket protection, quarry and mining grizzly screen, and rigging parts. Additional categories of mining wear parts and excavating wear parts include shovel bucket protections, shovel drive sockets and idlers, shovel rack and pinions, track pad pins and bushings, track pads, weld-on adapters, and wear caps.

Materials

Mining wear parts and excavating wear parts differ in terms of materials and features. Specialized materials for replacing wear parts include metal overlay clad with a harder alloy or carbide layer, cast manganese steel, high-chrome cast irons, Ni-Hard, cobalt alloys, cemented carbides, hardenable stainless steel, tool steels, martensitic steels, and austenitic steels. Manganese or high nickel steel can attain an austenitic structure, which work hardens and transforms to a harder martensite layer during end-use. Impact and wear resistance is provide by combining materials such as manganese steel wear strips, carbide wear buttons, or high chrome cast iron plates bonded to a ductile steel backing.

Applications

Mining wear parts and excavating wear parts are used to repair, maintain, and upgrade machinery and equipment such as backhoes, bucket excavators, cable shovels, continuous miners, dippers, dozers, draglines, dredging machines, earth movers, excavators, hard rock mining machines, and loaders. Mining wear parts and excavating wear parts are also used with tunneling and micro-tunneling equipment; mining equipment and strip mining equipment; shovels such as power shovels, steam shovels, and wire rope shovels; rippers, road headers, and trenchers; and track excavation machines, wall shearer loaders, and wheel loaders.
