Description
Metso C160 Fixed Jaw Plate (N11917389): “Quarry 2P” Profile & 4.2-Ton Mn18Cr2 Structural Casting
In the primary crushing circuit of a Metso C160 jaw crusher (1600mm x 1200mm feed opening), the fixed jaw plate (Part Number N11917389) is the critical static interface. Weighing 4,278 kg, this massive casting does not merely serve as a wear liner; it is the structural anvil that must absorb the full 12,000 kN compressive force generated by the pitman stroke. The “Quarry 2P” designation refers to a two-piece split configuration with a specific tooth profile optimized for quarry applications where feed material is abrasive (Silica > 10%) and competent (UCS > 250 MPa).
This technical dossier analyzes the engineering behind this 4.2-ton component. We examine the structural necessity of the two-piece design, the strain-hardening kinetics of the Mn18Cr2 alloy under heavy impact, and the precise machining required to prevent frame misalignment in large-scale operations.
“Quarry” Profile Geometry: Throughput vs. Wear Life
The “Quarry” tooth profile is engineered to balance two competing factors: nipping efficiency and wear metal volume.
- Nipping Angle Dynamics: The C160 operates with a deep crushing chamber. The “Quarry” profile features a specific pitch and depth (14-18mm) that maintains the nipping angle below the critical slip threshold of 24 degrees. This is essential for gripping large, rounded boulders in the upper chamber without “pop-outs.”
- Two-Piece (2P) Configuration: The split design allows for independent handling of the upper and lower sections. Since the lower section (crushing zone) experiences 70% of the abrasive wear, the 2P design enables independent replacement or rotation, significantly reducing the cost per ton compared to monolithic plates.
- Stress Distribution: The “Quarry” profile utilizes wide ridges to distribute point loading. While “Super Grip” profiles are sharper, they sacrifice wear life. The “Quarry” profile provides a robust cross-section that resists tooth breakage under the extreme shock loads typical of primary blasting muck piles.
Metallurgical Specification: High-Mass Mn18Cr2 Integrity
Casting a single piece of steel weighing over 4 tons requires sophisticated foundry controls to prevent centerline shrinkage. We utilize a Mn18Cr2 (ASTM A128 Grade C) chemistry tailored for heavy-section castings.
| Element / Property | Specification Value | Technical Significance |
|---|---|---|
| Manganese (Mn) | 17.5 – 19.0% | Stabilizes austenite in thick sections; delays fatigue cracking. |
| Chromium (Cr) | 1.8 – 2.2% | Carbide former; increases yield strength to prevent plastic flow. |
| Carbon (C) | 1.15 – 1.25% | Critical C/Mn ratio > 10 for optimal toughness. |
| Initial Hardness | 210 – 240 HBW | Ductile state for installation/break-in. |
| Work-Hardened Hardness | 500 – 550 HBW | Achieved under impact load > 200 MPa. |
| Impact Toughness | ≥ 140 J/cm² | Charpy U-Notch at -20°C (preventing brittle fracture). |
The Solidification Challenge:
In large castings like the N11917389, the cooling rate varies from the surface to the core. We employ advanced riser design and chills to promote directional solidification. This ensures the crushing face is dense and free of microporosity, while the mounting back remains sound. Post-cast heat treatment involves a precise soak at 1050°C followed by an aggressive water quench to freeze the austenitic structure, ensuring no brittle grain boundary carbides exist in the 100mm+ thick sections.
Manufacturing Precision: Machined Backs for Frame Protection
The interface between a 4,278 kg plate and the crusher frame is a critical structural junction.
Flatness Tolerance (0.3mm/meter):
We machine the back mounting surfaces of the N11917389 to a strict flatness tolerance.
Why? In a C160, the crushing force is immense. If the jaw plate back is rough or warped (as-cast), it bridges across the frame face. Under load, these bridges collapse or the plate flexes, causing fretting wear that gouges the frame. A machined back ensures 100% surface contact, transmitting the 12,000 kN load evenly into the front frame structure.
Wedge Locking Angles:
The upper and lower locking bevels are CNC machined to match the C160 wedge angles perfectly. This prevents vertical movement (“chatter”) during the return stroke, which is the primary cause of bolt failure and wedge damage.

Total Cost of Ownership (TCO) Analysis
For a C160 crusher, downtime costs are astronomical ($5,000+ per hour).
The Economy of Quality:
– Generic Plate: Poor fitment leads to frame wear. Lower Mn content leads to rapid wear (500 hours).
– Premium N11917389: Machined back protects the frame. Mn18Cr2 chemistry extends wear life to 750+ hours.
The extended life eliminates one changeout cycle per year. Saving 8 hours of downtime plus crane costs ($40,000+ value) makes the premium plate the only logical financial choice.
Engineer’s Advice: Field Operations & Maintenance
[Option B: Pro-Tip] – Managing Plastic Flow (Mushrooming):
Even with Mn18Cr2, the extreme forces in a C160 will cause some lateral expansion (plastic flow) of the jaw plate over time.
Action: Inspect the vertical gap between the fixed jaw and the cheek plates weekly. If the gap closes to less than 5mm due to mushrooming, trim the vertical edges of the jaw plate using a thermal lance or carbon arc gouging. Do not ignore this. If the plate expands until it presses hard against the cheek plates, it will become mechanically locked. Removing a “grown” 4-ton plate that is wedged into the frame is a nightmare scenario requiring days of lancing.
[Option C: Field Case Snippet] – The Importance of Intermediate Plates:
We often see operators reuse worn intermediate plates (the plate behind the jaw) or install new jaws on worn intermediates.
Result: The new N11917389 plate cracks horizontally within 100 hours.
Fix: The support must be flat. If you use intermediate shim plates, measure their thickness and flatness. If they are worn unevenly, replace them. Never bolt a new $5,000 jaw plate against a worn-out $500 shim plate.
