High-Performance High Manganese Fixed Jaw Plate for Toughened Crushing
High manganese fixed jaw plate components are a core part of jaw crushers, working with the movable jaw plate to crush materials like limestone and iron ore. At Shandong Jiujiu Machinery, we engineer these stationary "anchors" to provide the ultimate crushing foundation. As a key crusher spare parts, it endures continuous friction and impact, so its durability directly affects equipment efficiency. The choice of wear plate material is vital. It is usually cast with high manganese steel or other high-strength alloy steel, and the surface is specially heat-treated to form a base wear-resistant layer with a hardness of up to HB180-220, which can effectively resist the wear of materials such as ore and construction waste.
Engineering Stability and Material Integrity
Unlike other jaw crusher plates, the high manganese fixed jaw plate is stationary, forming a stable crushing cavity. The working surface is designed with a serrated or wavy texture, staggered with the movable jaw to optimize material reduction. This geometry is critical for "gripping" the feed material and preventing slippage, which can lead to energy loss and accelerated wear on the pitman.
These wear-resistant castings leverage work-hardening technology, ensuring the jaw liners become tougher under heavy compressive stress. When the fixed plate is struck by hard boulders, its surface molecular structure transforms, potentially increasing hardness to HRC 50+ in real-time, while the interior remains ductile to absorb the massive mechanical shock without cracking.
Strategic Maintenance for Global Mining
Regularly replacing worn crusher parts with our premium Mn13, Mn18, or Mn22 components minimizes maintenance downtime and enhances equipment uptime in mining and quarrying operations. Our manufacturing process utilizes Vacuum Sealed Molding to ensure the backing surface is perfectly flat. This precision prevents the "point loading" that causes fixed plates to snap under high pressure, protecting the crusher's main frame from expensive structural damage.
Primary Application Scenarios:
Hard Rock Mining: Primary crushing of granite, basalt, and iron ore.
Cement Production: Breaking down raw limestone for kiln feed.
Recycling: Handling concrete debris where high impact toughness is required to manage rebar inclusions.
Simplified FAQ
Q: How do I choose between Mn13 and Mn18Cr2 for my fixed jaw?
A: Mn13 is ideal for softer rocks like limestone. For highly abrasive materials like quartz or granite, Mn18Cr2 offers significantly better wear life by maintaining the tooth profile for longer periods.
Q: Can you customize the tooth profile (e.g., Wide Teeth vs. Sharp Teeth)?
A: Absolutely. We offer various tooth designs—including standard, quarry, and recycling profiles—to optimize your specific reduction ratio.
