High-Impact Forged & Cast Jaw Crusher Plates

Product Name: Heavy-Duty High-Manganese Replacement Fixed and Movable Jaw Plates for Primary Crushers

Description:

Maximize your primary reduction tonnage and secure non-stop quarry throughput with our premium 颚式破碎机颚板 (universally known as Jaw Liners 或 Tooth Plates). Serving as the brute-force crushing interface inside high-capacity primary jaw crushers, the fixed and movable jaw plates endure massive, continuous compressive loads and severe gouging abrasion as multi-ton boulders are forcefully wedged and fractured within the chamber.

We specialize in casting and custom-engineering elite-grade High-Manganese Steel ($\text{Mn}14\text{Cr}2$, $\text{Mn}18\text{Cr}2$, and $\text{Mn}22\text{Cr}2$) jaw liner profiles. Benefiting from modified alloy chemistries and proprietary water-toughness heat treatments, our jaw plates possess exceptional work-hardening capabilities. The moment hard abrasive rock (such as granite, river gravel, or iron ore) impacts the tooth ridges, the metallic surface rapidly morphs to establish a diamond-hard wear shield, while the underlying deep core retains its maximum structural ductility to eliminate the risk of brittle structural snapping.

Engineered to Prevent Tooth Flattening and Structural Snapping:

• Rapid Impact Microstructural Hardening: Under continuous dynamic compression, the operational skin of our liners work-hardens instantly from an initial HBW 200 straight up to HBW $500 – 550+$, drastically reducing abrasive wear and preventing premature tooth rounding.

• Precision Planar-Ground Backing Surfaces: The back seating surfaces of our jaw plates are precision-planed or CNC-ground to guarantee an absolutely flat interface against the crusher’s pitman or main frame. This eliminates localized stress concentrations and prevents backing-plate deformation or bolt stretching.

• Optimized Tooth Profiles for Superior Nipping: Available in Standard, Quarry, Super Tooth, Corrugated, Heavy-Duty, and Coarse tooth geometries. We customize the tooth pitch and valley depth to perfectly match your specific material moisture, feed size, and slabby rock configurations to completely eliminate chamber boiling.

Key Technical Highlights:

• Advanced Ultrasonic Structural Validation: Every single cast jaw plate undergoes mandatory Ultrasonic Testing (UT) and Magnetic Particle Inspection (MPI) to guarantee zero subsurface blowholes, internal gas porosities, or thermal cooling micro-cracks.

• Reinforced Wear Zones: Our proprietary molds feature localized extra metal thickness strategically placed at the high-wear lower third zone of the jaw profile, extending overall liner service life by up to $20\% – 40\%$.

• 100% Certified OEM Interchangeability: Guaranteed absolute drop-in compatibility and blueprint matches for globally recognized primary jaw crushing machinery, including Metso Outotec® (Nordberg C-Series like C106, C120, C140, C160), Sandvik® (JM and CJ Series), Terex® Jaques, Trio®, and Cedarapids®.
