Product Description
Crusher wear-resistant liner is a key component in the crusher, which is used to withstand the huge impact and wear during the material crushing process. At Shandong Jiujiu Machinery, we engineer these critical shields to protect your equipment's mainframe while maximizing the fragmentation efficiency of raw aggregates and ores. As the main internal working component, it directly crushes materials, bearing great pressure and friction. Without a high-performance lining system, the structural integrity of your crusher would degrade rapidly, leading to catastrophic mechanical failure and expensive repairs.
Advanced Metallurgy for Harsh Environments
To handle some harsh environments, crusher wear-resistant liners (also called crusher liner plates) are usually made of ultra-wear-resistant materials like high manganese steel, wear-resistant alloy, and high chromium alloy. We customize the chemical composition based on your specific feed material:
High Manganese Steel (Mn13, Mn18, Mn22): The industry standard for high-impact primary crushing. These liners feature "work-hardening" capabilities, where the surface becomes harder (up to 50-55 HRC) the more it is struck by heavy ore.
High Chromium Alloys: Ideal for secondary and tertiary crushing of highly abrasive materials like granite or basalt, offering a consistent hardness of HRC 58-62.
Martensitic Alloy Steels: A balanced choice for recycling applications where both toughness and abrasion resistance are required to handle concrete and rebar.
Precision Manufacturing and Application
These materials, with excellent wear resistance, high strength, and good toughness, ensure long-term stable and reliable operation of crusher liners and the whole crusher. Our manufacturing process utilizes Lost Foam Casting (LFC) and Vacuum Casting to ensure a smooth surface finish and precise dimensions. This precision is vital for a perfect fit against the crusher housing, preventing "fines" from migrating behind the liner and causing erosive "wash-out" of the machine frame.
Typical Application Scenarios:
Mining: Primary jaw and cone crushers processing iron, copper, and gold ores.
Quarrying: Impact and hammer crushers for high-quality aggregate production.
Cement Industry: Protecting raw mills and clinker crushers from continuous abrasion.
Essential FAQ
Q: How do I know when to replace my crusher wear-resistant liner?
A: You should monitor the thickness of the liner and the quality of the output. If the liner thickness is reduced by 70% or if you notice a significant drop in throughput, a replacement is necessary.
Q: What is the benefit of your heat treatment process?
A: Our specialized quenching and tempering cycles eliminate internal stresses and prevent "brittle snapping," ensuring the liner remains intact even under erratic feed loads.
