High Manganese Steel Casting Liner Plates for Ball Mills & Crushers
Product Description
Protect your critical mining equipment and extend its operational life with our premium High Manganese Steel Casting Liner Plates. Designed for extreme impact and abrasion environments, these liners are the ultimate defense for ball mills, sag mills, crushers, and chutes.
Manufactured using high-grade Mn13Cr2 and Mn18Cr2 steel, our wear-resistant liner plates feature exceptional work-hardening capabilities. Under high-impact conditions, the surface hardness can exceed 500 HB, while the core retains high toughness to prevent cracking. This unique property makes them the industry standard for mining, cement, and thermal power industries.
Key Features & Advantages
Exceptional Work-Hardening: The high manganese steel structure allows the liner surface to harden rapidly upon impact, providing superior wear resistance against grinding media and ores.
High Impact Toughness: Unlike brittle ceramic or chromium iron liners, our manganese steel castings can withstand severe shocks without fracturing, ensuring safety in high-stress crushing zones.
Customized Fit & Design: We utilize precision sand casting and lost foam casting to create liners with accurate dimensions, ensuring a perfect fit for your specific mill or crusher model.
Optimized Wave & Profile: Available in various profiles (wave, step, smooth) to optimize the lifting action of grinding balls and improve milling efficiency.
Cost-Effective Durability: Reduced downtime and longer replacement intervals mean lower total cost of ownership (TCO) for your plant.

Why Choose Yile Machinery for Your Wear Liners?
Material Expertise: We strictly control the Carbon (C) and Manganese (Mn) ratio and add Chromium (Cr) to enhance yield strength and wear resistance.
Advanced Heat Treatment: Our precise water-toughening treatment ensures the austenitic structure is stable, maximizing the performance of the manganese steel.
OEM & Customization: We can manufacture liners based on part numbers (e.g., Metso, Sandvik compatible parts) or your custom drawings.
Quality Inspection: Comprehensive testing including Dye Penetrant Inspection (DPI), Ultrasonic Testing (UT), and Hardness Testing before shipment.
Frequently Asked Questions (FAQ)
Q: When should I use Manganese Steel Liners vs. Chrome Steel Liners?
A: Manganese Steel Liners are best for applications with high impact (e.g., primary crushing, large ball mills) because they need impact to harden. Chrome steel is better for sliding abrasion with low impact.
Q: What is the lifespan of your Mn13Cr2 liner plates?
A: Lifespan varies by application, but generally, our optimized Mn13Cr2 liners offer 20-30% longer service life compared to standard Mn13 parts due to the added Chromium reinforcement.
Q: Can you provide bolts and fasteners for the liners?
A: Yes, we provide a complete solution, including high-strength liner bolts, washers, and nuts to ensure secure installation.
