Heavy Duty Jaw Crusher Jaw Plates Custom Cast Wear Parts for Hard Ore Rock Crushing

Heavy Duty Jaw Crusher Jaw Plates Custom Cast Wear Parts for Hard Ore Rock Crushing

Product Description

We are a professional manufacturer focused on heavy‑duty mining wear castings. Our material portfolio covers high manganese steel, high‑chromium alloy, alloy steel and ductile iron. Beyond mill liners and cone crusher consumables, we deliver tailored jaw crusher wear components for global quarry, mining and construction clients.

Jaw plates consist of movable jaw plate and fixed jaw plate, acting as the core crushing working parts inside jaw crushers. Fitted respectively on the pitman and main crusher frame, the pair forms the crushing cavity. As the movable jaw performs reciprocating swing motion, strong squeezing, splitting and bending force is generated to break large lumps of rock and ore. Subjected to cyclic impact and continuous abrasive wear, jaw plates require balanced impact toughness and surface hardness to resist chipping, cracking and premature failure.

We can develop products according to customer drawings, physical samples or actual site operating conditions. Multiple tooth profiles can be configured. Different tooth shapes are applied to accommodate varying feed size, rock hardness and target throughput for mining, quarrying, aggregate and building‑material sectors.

Applications

Jaw plates are mainly used in primary coarse crushing operations. They handle tough, abrasive raw materials including iron ore, copper ore, gold‑bearing ore, granite, basalt and cobblestones.

Typical application scenarios include mineral processing plants, quarry aggregate production, highway construction and building‑material production. Our cast jaw plates fit a wide range of jaw crusher models. Optional tooth configurations such as wave tooth, sharp tooth and flat tooth help users achieve desired feeding capacity and crushed product size.

Production and Quality Inspection

The whole casting workflow starts with drawing‑based process optimization, followed by sand formulation, moulding and core‑making, mould closing, smelting, pouring, shakeout and surface cleaning, ending with targeted heat‑treatment procedures. Two mature casting technologies, ceramic bonded resin sand casting and lost‑foam vacuum casting, are deployed to satisfy different part weights and order volumes.

Every batch undergoes full‑set quality validation. Heat‑treatment relieves residual internal stress and improves comprehensive mechanical performance. Hardness testing assesses surface wear‑resistance performance. 3D scanning captures full‑part contours, with special focus on tooth profile accuracy which directly affects crushing efficiency. MT magnetic particle testing screens surface and near‑surface cracks. UT ultrasonic testing locates hidden interior defects including porosity, slag inclusions and shrinkage cavities. Chemical composition analysis verifies material compliance against technical specifications. Metallographic analysis evaluates metal microstructure to ensure qualified matrix condition. Dimensional inspection with calipers, micrometers and coordinate measuring machines validates mounting surfaces, bolt hole positions and overall outlines. Each finished jaw plate is subject to simulated fitting check to eliminate assembly risks at customer site.

Support and Services

We provide customised solutions oriented to real‑world site conditions, including rock hardness, maximum feed size and required hourly throughput. Our engineering team offers targeted recommendations for material grade and tooth pattern selection to extend service life. Our factory holds ISO 9001, ISO 14001 and ISO 45001 system certifications. Complete batch‑traceability archives are maintained for each order. Third‑party inspection can be arranged at customer’s request. Bilingual Chinese‑English inspection reports are supplied for export clearance and project acceptance. Practical guidance covering on‑site installation, replacement and daily maintenance is also available for end‑users.

Packing and Shipping

Considering heavy weight and protruding tooth structures of jaw plates, we adopt export‑grade heavy‑duty packaging. Fumigated solid wooden cases and high‑load pallets together with thick waterproof wrapping are used to prevent collision, dent and moisture damage during long‑distance ocean or land transit. Each package is clearly marked with PO number, destination, part designation, quantity, gross / net weight and outer dimensions. Sea, land and air shipping options are all accessible. Our logistics team manages factory loading, document preparation and shipment follow‑up until goods safely arrive at destination ports or job sites.
