　　Product Highlights 
　　1. Increased lifespan, reduced downtime: We provide customized wear-resistant material solutions for customers with ultra-long service requirements. By using inlaid liner plates, we can extend the service life of liners by up to twice that of conventional products under specific operating conditions, thereby reducing replacement frequency at the source and significantly improving line uptime. 
　　2. A wide range of materials: High-manganese steel plus custom‑selected special alloys. We maintain standard stock in four major grades—ZG120Mn13, ZG120Mn13Cr2, ZG120Mn18Cr2, and Mn22Cr2—while also offering tailor‑made solutions with other specialized materials and bimetallic composite liners, ensuring precise alignment with varying ore hardness and operating conditions. 
　　3. 100% inspection before shipment, with full quality traceability: materials and dimensions are inspected piece by piece, and only qualified products are delivered. 
　　User Pain Points 
　　In primary and secondary crushing operations at mines, cone crusher liners are subjected to harsh operating conditions characterized by high‑impact loads and abrasive mineral materials, leading to rapid wear and frequent replacement. This results in increased downtime, reduced throughput, and a direct negative impact on the consistency of product particle size as well as the efficiency of downstream grinding processes. Moreover, issues such as mismatched installation dimensions and limited material options provided by suppliers further exacerbate the dual burden of procurement and operation. 
　　Solution 
　　Our company’s cone crusher liners are specifically designed for secondary and fine crushing applications in mining. We offer a range of high-manganese steel grades, including ZG120Mn13, ZG120Mn13Cr2, ZG120Mn18Cr2, and Mn22Cr2, which provide excellent work-hardening properties to significantly reduce downtime for replacement. For conditions involving high impact and severe abrasion, we can customize bimetallic composite liners to extend service life. Our products are precisely matched to various models of cone crushers from major domestic and international manufacturers and are ready for installation upon arrival. 
　　I. Product Description 
　　Our company manufactures a series of high-manganese steel mantle and bowl liners for cone crushers, specifically designed for primary and secondary crushing applications in mining. These products are compatible with all models of cone crushers from major domestic and international manufacturers. The largest single liner we produce weighs approximately 7,700 kg, fully meeting the requirements of large-scale crushing equipment. Additionally, we offer customized wear-resistant liners for customers with stringent service-life demands, significantly extending liner lifespan.

　　III. Product Features and Advantages 
　　• High wear resistance: The liner material is alloyed with high-manganese steel, effectively resisting severe crushing and impact wear from ore, significantly extending service life and reducing the frequency of shutdowns for replacement. 
　　• High Compatibility: Manufactured strictly according to customer drawings, our products precisely match the various models of cone crushers from major OEMs, allowing for immediate installation upon arrival. 
　　• Long‑Life Customization: We offer tailored wear‑resistant material solutions for customers with exceptionally long service‑life requirements. By inlaying alloy inserts into the liner plates, we can extend liner life to approximately twice that of standard products, significantly reducing overall operating costs. 
　　• Extra-large specifications: The maximum single liner weighs approximately 7,700 kg, and we possess the production capacity to supply liners for both large and extra-large crushing equipment. 
　　IV. Why Choose Us 
　　• Specializing in wear-resistant castings for harsh operating conditions: We are not a foundry chasing short-term deals; instead, we are rooted in China, focusing on the R&D and manufacturing of wear-resistant castings for demanding environments such as mining and power generation. Take crushing head liners (fixed mantle liners) as an example: specifically optimized for the high-impact, high-wear conditions of coarse and fine crushing in cone crushers, these components undergo water‑toughening treatment of high-manganese steel, resulting in impact‑hardened surfaces reaching HB500–600 while maintaining high core toughness. This design withstands continuous compression and impact from ore without fracturing, significantly extending replacement intervals and reducing downtime risks at the source. 
　　• We let the data speak, not empty promises of perfection: Casting processes are complex; we do not claim “zero defects,” but we do commit to “zero excuses.” Each batch of crushing mantle undergoes a comprehensive inspection process—including hardness testing, precise dimensional measurements, and magnetic particle inspection—to ensure the accuracy of the crushing chamber geometry and mounting surfaces, guaranteeing precise alignment with the moving cone liner and stable chamber dimensions. Complete test reports accompany every batch, demonstrating our accountability through data and action. 
　　• Long-term partnerships—delivery is just the beginning: Our digital systems let you track production progress in real time, eliminating opaque operations; we respond immediately to quality concerns without delay; and every shipment includes a detailed test report for your quality records. We believe that a supplier’s attitude toward resolving issues truly reflects its value. 
　　V. Production and Quality Assurance 
　　• Premium Raw Materials: Carefully selected high-quality scrap steel and punched billets, free of rust and oil, ensure the purity of the material at the source, laying the foundation for work-hardening in high-manganese steel. 
　　• Ultimate density: Ceramic sand combined with a large-diameter heating riser eliminates shrinkage porosity and cavities, ensuring a dense microstructure within the crushing wall and preventing cracking under high-load extrusion. 
　　• Precision melting: Melted in a Fuji electric furnace from Japan, with real-time compositional verification via spectrometer to precisely control carbon and manganese levels, ensuring work-hardening capability and impact toughness. 
　　• Flawless casting: 850°C preheating of the ladle combined with bottom-pouring technology eliminates sand‑hole defects, resulting in a smooth working surface on the mill shell wall free of casting imperfections. 
　　• Strengthened metallography: 30-second rapid quenching yields a single austenitic microstructure, achieving an “hard outside, tough inside” condition for the rolling bowl wall—surface hardness reaches HB500–600 while the core retains high toughness. 
　　• Powerful shot blasting: cleans and hardens the surface, enhancing the wear resistance of the working face of the crushing wall. 
　　• Rigorous quality inspection: magnetic particle testing ensures precise crushing chamber geometry and internal defect-free integrity. 
　　• Transparent delivery: Scan a code to track progress in real time, with full visibility from material input to shipment. 
　　VI. Frequently Asked Questions (FAQ) 
　　Q1: What is the minimum order quantity for cone crusher liners? 
　　Minimum order quantity is one piece. Bulk purchases qualify for discounted pricing. 
　　Q2: What is the delivery time? 
　　Custom-made liners based on your drawings take 45–60 days. Rush orders can be expedited upon negotiation. 
　　Q3: What packaging options are supported? 
　　Secured with iron brackets and protected with stretch wrap, or packed in wooden crates, to meet the sea and land transportation requirements for liners. 
　　Q4: Can the customer’s logo be printed on the packaging? 
　　Yes, but cast lettering is only supported on the non-working surface of the casting.
