Tungsten Carbide Jaw Plate for Jaw Crusher

Description Of Tungsten Carbide Jaw Plate for Jaw Crusher

Tungsten Carbide Jaw Plate for Jaw Crusher is a high-performance wear component manufactured from tungsten carbide (WC) with a metallic cobalt binder through powder metallurgy and advanced HIP (Hot Isostatic Pressing) sintering processes. These jaw plates are designed to be installed as the fixed jaw and swing jaw crushing surfaces in jaw crushers, providing exceptional wear resistance and significantly extending the service life of the crushing chamber.

Jaw crushers are the primary crushing equipment in mining, quarrying, and aggregate production, handling some of the most abrasive and demanding materials — granite, basalt, quartzite, iron ore, and silica-rich ores. Traditional jaw plates made from high manganese steel (Mn13, Mn18Cr2, Mn22Cr2) rely on work-hardening to resist wear, but in highly abrasive, low-impact conditions — such as silica-rich ores — manganese steel wears rapidly, typically lasting only 2–4 weeks.

Tungsten carbide jaw plates precisely address this limitation. With hardness ranging from HRA 86 to 92 — far surpassing the 500–550 HB that work-hardened manganese steel can achieve — tungsten carbide maintains its protective geometry through the most abrasive conditions.Field data confirms the advantage: in highly abrasive ores (silica >70%), carbide liners achieve 8–12 weeks of service life versus 2–4 weeks for manganese steel.A well-documented field case from a Philippines quarry showed TiC composite plates lasting 412 hours compared to 160–165 hours for Mn18Cr2 plates under identical feed conditions — approximately 2.5 times longer service life.

Tungsten carbide jaw plates are available in multiple grades and configurations — including full plates, composite plates with carbide inserts, and custom designs — to suit different crusher models, feed materials, and operating conditions. All products are manufactured using 100% virgin tungsten carbide raw materials with HIP sintering for uniform microstructure and superior mechanical properties.

Applications Of Tungsten Carbide Jaw Plate for Jaw Crusher

Mining — Primary Crushing: Tungsten carbide jaw plates are widely used in primary jaw crushers for crushing hard, abrasive ores including granite, basalt, quartzite, iron ore, copper ore, and gold ore. They are particularly effective in high-silica feed materials where manganese steel fails rapidly.

Quarrying and Aggregate Production: Carbide jaw plates are used in quarry operations for producing construction aggregates from hard rock. They maintain crushing chamber geometry longer, ensuring consistent product size and throughput.

Cement and Construction Materials: Tungsten carbide jaw plates are used in cement plants for crushing limestone, clinker, and other raw materials. The extreme wear resistance reduces downtime and maintains production efficiency.

Recycling and Construction Waste: Carbide jaw plates are used in jaw crushers for processing construction and demolition waste, including concrete and asphalt recycling.

Ferroalloy and Special Materials: Tungsten carbide jaw plates are suitable for crushing hard materials such as ferroalloys, cemented carbide scrap, artificial crystals, calcium-silicon, and ferro-silicon.

Usage Precautions and Limitations Of Tungsten Carbide Jaw Plate for Jaw Crusher

Installation: Tungsten carbide jaw plates must be properly installed and securely fastened to the jaw crusher frame. Ensure proper alignment and torque specifications to prevent plate movement or breakage during operation.

Handling and Storage: Tungsten carbide jaw plates are hard but brittle. Handle with care to avoid chipping or cracking. Store in a dry, clean environment to prevent contamination.

Regular Inspection: Regularly inspect jaw plates for wear or damage. Replace plates when wear reaches the replacement limit or when carbide is chipped or cracked. Avoid striking carbide surfaces with hammers.

Compatibility Verification: Before ordering, verify that the plate dimensions, grade, and mounting configuration are compatible with your specific jaw crusher model and brand.

Working Condition Considerations: Jaw crushers operate under extremely harsh conditions with high impact forces and abrasive materials. The carbide jaw plates must be able to withstand very high impact while maintaining sufficient wear resistance to maximize service life.

Quality Assurance: Ensure that the supplier provides material certification including chemical composition, hardness, density, TRS values, dimensional inspection reports, and compliance with relevant standards.
