High Manganese Steel Jaw Crusher Plates Customized Wear Resistant Casting Parts for Mining Industry

Product Description

We manufacture high-end castings using a variety of materials, including high manganese steel, high chromium alloy, alloy steel, and ductile iron. Our product range includes jaw crusher plates, ball mill liners, and autogenous or semi-autogenous mill liners for the mining industry.

The jaw plate in the image is a heavy-duty wear part featuring a reinforced grid structure and precise mounting holes. It is a critical component in the crushing cavity. Unlike liners that handle sliding abrasion, the jaw plate endures extreme squeezing, bending, and high-impact forces from large rocks. It acts as a protective armour for the crusher frame while directly transferring crushing force to the material. By optimizing the tooth profile and material flow, it enhances primary crushing efficiency. We custom manufacture these plates to match specific working conditions in mining, cement, power, chemical, and engineering machinery sectors.

Applications

These jaw crusher plates are primarily used for the coarse crushing of metallic ores. They handle high-hardness bulk materials such as copper, gold, and iron ore. They are also widely applied in mineral processing, building materials, cement, power plants, and chemical industries. Whether used in aggregate production or primary ore processing, our wear-resistant castings deliver reliable performance under severe impact and continuous abrasion.

Production and Quality Inspectio

Jaw plates are heavy-section castings with deep ribs and precise mounting holes. Their production requires tight control of melting, pouring, and cooling to avoid internal defects. Our manufacturing process covers process preparation, sand mixing, molding and core making, box closing, melting, pouring, shakeout and cleaning, and heat treatment. We use ceramic bonded resin sand and lost foam vacuum casting lines to ensure stable filling and feeding of thick sections.

Quality control is carried out at every critical stage:

• Heat treatment is performed to relieve internal stress, refine grain structure, and achieve the required combination of hardness and toughness.

• Hardness testing on the working surface confirms the wear resistance index meets specification.

• 3D scanning checks the overall geometry, rib dimensions, and mounting hole positions against the drawing.

• MT magnetic particle testing detects surface and subsurface cracks, especially around ribs and bolt holes.

• UT ultrasonic testing inspects the internal soundness of thick sections, identifying porosity, slag inclusion, and shrinkage cavity.

• Chemical composition detection verifies the melt and the final casting match the required grade.

• Metallographic analysis examines the matrix structure to ensure the desired carbide distribution and absence of overheating.

• Dimensional inspection using calipers, micrometers, and coordinate measuring machines confirms installation interfaces and bolt hole spacing are within tolerance.

• Bolt trial assembly is performed on every plate to guarantee smooth fitting on the crusher frame
