Crusher Plant Spare Parts — Wear Parts

All wear and spare parts for crusher and concrete plants: jaw plate, blow bar, mantle & concave, wear-resistant cast liners, vibrating screen mesh, conveyor idler, drum pulley, belt rubber and motor. Austenitic manganese steel and high-chrome iron; supply from stock, factory/site delivery, cross-brand aftermarket fit and a low cost-per-ton target. General Machinery supplies the full range of wear and spare parts for every brand of crusher, screen, feeder and conveyor plant: jaw plate, blow bar, mantle & concave, wear-resistant cast plates and liners, vibrating screen mesh, conveyor idlers, drum pulleys, belt rubber and motors. With over 45 years of industry experience, parts ship from stock with factory/site delivery and on-site installation or remote support. Wear metallurgy — choosing the right alloy Wear is driven by the free quartz/silica content (Bond abrasion index Ai) of the feed, not by Mohs hardness. The right alloy is the foundation of TCO: TCO sales argument — the right metric is cost per ton Wear parts are the main operating cost of a plant. The correct metric is not part price but cost per ton crushed. TCO = part price + replacement frequency + downtime + safety of heavy part changes. The wrong technology (high-chrome on abrasive rock) is consumed in hours. Fast supply from stock + site delivery + on-site installation minimize downtime and lower cost per ton. Scope and supply Material-specific recommendation For limestone and clean abrasive feed use high-chrome; for coarse, high-impact rock such as granite/basalt use manganese/martensitic steel and consider ceramic; for metal-contaminated C&D recycling use manganese/martensitic (chrome is brittle, tramp-iron risk). Cross-brand parts are supplied for any make of crusher. S: How do I choose a wear part? C: Base it on the free quartz/silica content of the feed (Bond Ai), not Mohs hardness. High abrasion calls for high-chrome or ceramic-MMC; high impact and coarse feed call for austenitic manganese steel. S: What is the right cost metric? C: Not part price but cost per ton crushed. TCO = part price + replacement frequency + downtime + safety. Stock and fast delivery cut downtime and lower cost per ton. S: What material is a jaw plate made of? C: Usually austenitic manganese steel (Mn13/Mn18, ASTM A128). It work-hardens under impact, with surface hardness rising from 200 to 550 HB, suiting high impact and coarse feed. S: Do you supply parts for other brands of crusher? C: Yes. Castings, screen mesh, conveyor idlers/pulleys/belt rubber and motors are supplied cross-brand from stock, fitting any make of crusher, screen and conveyor. S: How are delivery and installation handled? C: Parts are delivered ex-factory or to site. We provide on-site installation or remote technical support; fast supply from stock minimizes downtime.
