The selection of liner plates for construction waste crushers needs to take into account impact resistance, wear resistance and economy. Due to the complex composition of construction waste (including concrete blocks, masonry, steel bars, etc.), the liner plates need to cope with high-intensity impact and mixed wear. High manganese steel (such as Mn13) is the mainstream choice. Its surface hardening characteristics after impact can effectively resist the wear of concrete fragments, while the tough matrix can withstand the instantaneous impact of steel bars. For working conditions with high steel content, chromium-molybdenum alloy steel liner plates are often used to improve tensile strength and corrosion resistance by adding chromium and molybdenum elements. In recent years, the application of composite liner plates has increased, such as surfacing high chromium alloy layers or inlaying tungsten carbide blocks on high manganese steel substrates, which not only maintains overall impact resistance, but also enhances wear resistance in key wear areas. Some light-load crushing links will use replaceable modular wear-resistant alloy liner plates to reduce maintenance costs. liner plate designs often use wavy or teethed surface structures to improve crushing efficiency and disperse stress. In general, the liner plate of the construction waste crusher needs to be flexibly selected according to the hardness of the material, the content of metal impurities, etc., to achieve a balance between crushing efficiency and service life.
