Fixed Jaw Plates & Movable Jaw Plates are core wear components of jaw crushers, forming the crushing chamber to exert compressive force on raw materials. Crafted from high-manganese alloy steel and subjected to quenching-tempering treatment, they integrate exceptional abrasion resistance and impact toughness—extending service life by 3x compared to ordinary carbon steel plates. This durability directly cuts crusher downtime by 45% for mining and aggregate operations, where continuous crushing is critical to productivity.
Work-Hardening Material System: Manganese content up to 22% with 1.5% chromium reinforcement, enabling surface hardness to rise from 220 BHN to 480-550 BHN after 24 hours of operation, adapting to hard rock crushing demands.
Optimized Tooth Profile Design: Asymmetrical triangular teeth with 15° inclination angle enhance material gripping and prevent slipping, increasing crushing efficiency by 20% versus standard flat-profile plates.
OEM Compatibility & Customization: Precision-machined to match dimensions of Metso C Series, Sandvic JS Series, and Terex Jaques crushers with tolerance ≤0.3mm; custom sizes available for non-standard jaw crushers within 7-10 days.

Mining Primary Crushing: Handling run-of-mine (ROM) ore (iron, copper, gold) with particle sizes up to 1.2m, reducing feed to 100-300mm for secondary processing.
Quarry Aggregate Production: Crushing granite, limestone, and basalt into construction-grade aggregates (20-50mm) for concrete and road base.
Recycling Industry: Shredding concrete debris and asphalt waste in demolition recycling plants, ensuring uniform particle size for reuse.
Uneven feeding (e.g., oversized chunks >80% of chamber width) and lack of lubrication between the movable jaw and toggle plate can reduce lifespan by 60%. Solution: Install a vibrating feeder for uniform material distribution and lubricate contact points every 8 hours of operation.
