Ore Mining high manganese steel Cone crusher Mantle and concave

Cone crusher mantle and bowl liner are key wearable parts for secondary and tertiary fine crushing, widely used in mining ore processing, highway construction aggregate production, cement plant raw material crushing, and hard stone processing industries. These liners undertake repeated impact, squeezing and abrasive wear of hard materials, and are critical to controlling finished stone particle size, output capacity and equipment operating stability. Our cone liners are fully adaptable to all series of Symons, Metso, Sandvik and Terex cone crushers.

We provide diversified professional material solutions for different working scenarios, including standard Mn13 high manganese steel, upgraded Mn18Cr2 high toughness manganese steel, and high chromium composite alloy materials. For medium-hard limestone and common rock crushing, standard manganese steel ensures cost performance. For high-hardness ore, granite and basalt fine crushing, super high manganese and high chromium materials effectively resist strong abrasion and impact load. All raw materials are high-purity alloy ingots without recycled inferior materials.

Adopting advanced lost foam casting and precision sand casting technology, our cone liners achieve dense internal structure, no shrinkage cavity and no deformation. Standard professional heat treatment process stabilizes product hardness and greatly improves surface work-hardening ability. Optimized crushing cavity curve design realizes even material distribution, smooth crushing process, uniform finished particle size and higher finished product rate.

Our cone crusher liners effectively solve common problems of traditional liners such as easy cracking, rapid wear, uneven discharge and short service life. Strict dimensional tolerance control guarantees seamless installation and perfect compatibility with original equipment. Each product is inspected for metallographic structure, mechanical strength and wear resistance before shipment.

We focus on long-term cooperation benefits for global clients. Our cone wear parts feature longer service life, lower comprehensive operating costs and more stable continuous production performance. We support conventional stock products and personalized OEM casting to provide one-stop wearable part solutions for global crushing enterprises.
