Crusher and Mill Wear Parts

Crusher wear parts and mill wear parts include commonly-replaced components such as jaws, rolls, blades, plates, and liners for material processing equipment. The aggregate, cement, metallic mining and surface mining industries use a variety of products. For example, aggregate and cement companies replace crusher and mill wear parts in gyratory crushers, cone crushers, jaw crushers, roll crushers, hammermill crushers, and impact crushers. The metallic mining and surface mining industries purchase replacement parts for mining shovels, gyratory crushers, cone crushers, and grinding mills. They also replace drop breakers, conveyor parts, wear plates, drag chain, dragline teeth, rope sockets, equalizer bars, liners, and structural components. Coal-fired power plants replace crusher and mill wear parts such as wear tires, grinding rolls, wear track segments, grinding rings, grinding balls, housing units, and roll brackets in coal pulverizers. They also purchase replacement cam sectors, anvil plats, combing plates and side wear plates for ash crushers.

Crusher wear parts and mill wear parts are also used in the scrap shedding, solid-waste recycling, and brick manufacturing industries. Scrap shredders need to replace grates, roof covers, kick-out doors, feed rolls and feeder flights, side liners, rotor caps, breaker bars, rotor assemblies, shredder hammers, and bolt-in liner plates. Solid-waste recyclers need wear-resistant hammers and longer-lasting grates. The brick manufacturing industry uses crusher and mill wear parts such as extruder knives, cast augers, scarper blades, hammermill impact bars, hammermill liners, muller tires, roll shells, put mill mixer knives and paddles. These crusher wear parts and mill wear parts are designed to minimize wear, resist abrasion, improve production, and reduce downtime. Specialized suppliers of crusher and mill wear parts may also provide machinery bases, bearing boxes, press platens, thermal-plant pulverizer parts, dredge machinery components, retainers, and custom-made components for mining and milling machinery.

Crusher wear parts and mill wear parts are made from metal alloys and then weld-assembled, stress-relieved, and subjected to non-destructive testing (NDT). High-chromium alloy irons are treated in furnaces with programmable controls to achieve consistent properties and a longer wear life. Crusher and mill wear parts that are lined with a high-carbide layer are designed resist abrasion and increase wear-life. Cutting surfaces remain sharp throughout much of the life of the crusher part, increasing shredder efficiency. Crusher and mill wear parts for gyratory crushers, cone crushers, jaw crushers, roll crushers, hammermill crushers, and impact crushers are sometimes made from proprietary, manganese steels such as Xtralloy (Columbia Steel Casting Co.)
