Jaw Plates (Fixed & Movable Jaw Dies)

High-performance jaw plates engineered in Mn13–Mn22 austenitic manganese with optional TiC inserts. Optimized tooth profiles for aggregate, mining, recycling, and cement operations.

Overview & Function

Jaw plates are the primary wear components consisting of a fixed jaw plate mounted to the crusher frame and a movable jaw plate attached to the pitman. The crushing action occurs through compression between these surfaces.

Critical Setup Factors: CSS (Closed Side Setting), nip angle, choke feed conditions, and proper seating are essential for optimal performance and extended wear life.

Available Configurations

  • Materials: Mn13, Mn18, Mn22 with optional TiC reinforcement
  • Tooth Profiles: Standard Quarry, Super Grip, Flat/Non-Corrugated, Recycling
  • Mounting: Bolt-on or wedge retention systems
  • Brands: Metso, Sandvik, Terex, Powerscreen, Kleemann, McCloskey

Manufactured from Mn14Cr2 to Mn18Cr2 alloys that work-harden under impact, providing extended service life in abrasive conditions.

Contoured Profile

Precision-profiled to match crushing chamber geometry, ensuring optimal material flow and uniform wear distribution.

Secure Mounting

Multiple mounting configurations available for bolt-on installation with precision-drilled holes matching OEM specifications.

⚠️ Maintenance Tip: Inspect cheek plates regularly and replace when thickness reduces to 70% of original. Operating with worn cheek plates risks expensive frame damage.

Toggle Assemblies (Toggle Plates, Seats & Beams)

Critical safety and force transmission components protecting your crusher from damage due to uncrushable materials.

Toggle System Function

The toggle assembly serves dual purposes: transmitting crushing force from the pitman to the movable jaw, and acting as a mechanical fuse to protect the crusher when uncrushable material enters the chamber.

Complete Assembly Includes

  • Toggle Plate (cast steel or cast iron)
  • Pitman Toggle Seat (hardened steel)
  • Frame Toggle Seat (hardened steel)
  • Toggle Beam (cast/fabricated steel)
  • Tension Rod & Springs

Troubleshooting — Read the Wear Pattern

Common jaw liner wear signatures and recommended actions

❌ Top Third Worn Faster

Likely Cause: Open CSS / poor nip angle / uneven feed distribution

Recommended Action: Reduce CSS, improve feed presentation, consider deeper tooth profile

⚠️ Tooth Rounding / Scalloping

Likely Cause: Abrasive fines; inadequate tooth hardness for material

Recommended Action: Upgrade to Mn + TiC reinforcement; adjust CSS to maintain nip angle

📍 Center Localized Wear

Likely Cause: Material bridging / slabby feed characteristics

Recommended Action: Improve scalping operation; consider super-tooth or slab-breaker profile

🔧 Cracking / Chipping

Likely Cause: Tramp metal contamination / mis-seated plates / improper torque

Recommended Action: Improve metal detection; verify seating & torque; prefer higher Mn grade

Frequently Asked Questions

What information do I need to order jaw crusher parts?

We need your crusher make (Metso, Sandvik, etc.), model number (C110, CJ411, etc.), and ideally the OEM part numbers for the components you need. If you don’t have part numbers, photos and measurements can help us identify the correct parts.

Are your parts compatible with OEM equipment?

Yes, our parts are manufactured to meet or exceed OEM specifications. They are direct replacements and will fit and function exactly like original parts. We provide 100% dimensional accuracy guarantee.

What is the typical lead time for jaw crusher parts?

Stock items ship within 1-3 business days. Standard wear parts (jaw plates, cheek plates) typically 2-4 weeks. Major components (pitman, eccentric shaft) 6-12 weeks. We offer expedited service for critical needs.

Do you offer warranties on your parts?

Yes, all our parts come with a manufacturer’s warranty covering defects in materials and workmanship. Wear parts: 3-6 months depending on application. Mechanical components: 12 months standard.

Can you supply parts for older or discontinued crusher models?

Absolutely. We have extensive reverse-engineering capabilities and can manufacture parts for obsolete models. We may need to inspect your existing parts or crusher to ensure perfect fit.

What documentation do you provide with parts?

We provide material certificates (mill certs), heat treatment reports where applicable, dimensional inspection reports, and packing lists. Additional documentation available upon request.

Do you ship internationally?

Yes, we ship worldwide. We have experience with international logistics and can arrange delivery to any location. We handle all export documentation and can ship via air or sea freight.

Can you help with installation and technical support?

Yes, we provide technical support for all our parts including installation guidance, troubleshooting assistance, and maintenance recommendations. Field service support can be arranged for major installations.

How long do jaw plates typically last?

Jaw plate service life varies significantly by application. Soft limestone/dolomite may see 2,000-4,000 hours with Mn13 or Mn18. Hard granite/basalt typically delivers 800-2,000 hours with Mn18 or Mn22. River gravel ranges 1,200-3,000 hours depending on silica content. Concrete recycling sees 600-1,500 hours with proper tooth profile. Iron ore typically achieves 500-1,200 hours with Mn22 + TiC inserts.

These estimates assume proper CSS settings, choke feed conditions, and regular inspection. See detailed service life guide →

What causes premature jaw plate wear?

Common causes include: tooth polishing from fines (pre-screen to remove -10mm material), open CSS operation reducing crushing force, one-side feed creating uneven wear, wrong alloy selection for rock type, and poor seating preventing work-hardening. See our troubleshooting guide for detailed diagnostics.

Which jaw plate tooth profile should I use?

Tooth profile selection depends on your feed and application. Standard/Corrugated is most versatile for general quarrying. Super Grip/Deep Tooth works best for large, irregular, slabby feed. Flat/Non-Corrugated suits soft rock and controlled gradation. Recycling Profile handles concrete/asphalt with rebar. View complete tooth profile guide →

What are the advantages of TiC-reinforced jaw plates?

TiC (Titanium Carbide) inserts provide edge protection in highly abrasive applications: extended edge life (1.5-2× longer than plain manganese), CSS stability through slower tooth rounding, optimal load distribution, and cost effectiveness in siliceous feeds. Best for iron ore, hard granite, quartzite, siliceous gravel. Not recommended for heavy tramp metal risk or recycling with rebar.

How do I choose between Mn13, Mn18, and Mn22 jaw plates?

Select based on rock hardness and abrasiveness. Mn13 (12-14% Mn) suits softer rock like limestone. Mn18 (17-19% Mn) is the most popular grade for granite, basalt, river rock. Mn22 (20-24% Mn) is for very hard, abrasive rock like iron ore. Rule of thumb: start with Mn18 for general quarrying. Detailed material selection guide →

Can jaw plates be rebuilt or refurbished?

Manganese jaw plates can sometimes be rebuilt through hardfacing, but with limitations. Rebuilding works when plates have adequate remaining thickness (>50% original), no cracks, and proper tooth form still visible. However, rebuilt sections don’t work-harden like original cast manganese, and subsequent wear life is typically 40-60% of new plates. Replacement is usually more economical for small-medium crushers.

What installation mistakes cause jaw plate failures?

Common installation errors include: poor seating (gaps behind plate), incorrect torque (over/under-torquing), dirty mounting surfaces, mismatched profiles on fixed vs. movable jaw, and no re-torque after warm-up. Always verify <0.5mm gaps with feeler gauges, follow OEM torque specs, and re-torque after 1-2 hours of operation.

How do I calculate cost per ton for jaw plates?

Cost per ton = (Plate set cost + Installation labor + Downtime cost) ÷ Tons processed. Include all costs: purchase price, crew hours for installation, and lost production during changeout. Premium alloys (Mn22 + TiC) cost more upfront but often deliver lower cost/ton through extended life. Focus on cost per ton, not purchase price alone.
