三、典型应用场景
1.矿山破碎系统
圆锥破碎机：
A413139作为动锥衬板或定锥衬板，与锰钢衬板相比，耐磨性提升30%-50%，减少停机更换频率，适用于铁矿石、铜矿石的中细碎。
颚式破碎机：
若为颚板，采用分层破碎设计，上段粗碎、下段细碎，提高能量利用率，降低能耗15%-20%。
2.筛分设备
振动筛筛网：
若A413139为聚氨酯筛网，具有自清洁功能，防止湿料堵塞，筛分效率≥90%，适用于煤炭、砂石的分级。
3.输送系统
托辊或滚筒：
若为输送带托辊，采用密封轴承设计，防护等级IP65，防止粉尘侵入，使用寿命≥50,000小时，减少皮带跑偏风险。
四、优势特点
1.材料与工艺优势
高铬合金材质：
相比传统高锰钢，耐磨性提升2-3倍，尤其适合高硬度、高磨蚀性物料。
精密铸造工艺：
采用消失模铸造或V法铸造，确保尺寸精度±1mm，减少安装间隙，降低运行噪音。
2.定制化设计
模块化结构：
支持分块更换（如破碎机衬板分为上、中、下三段），降低单次更换成本。
快速安装接口：
预留螺栓孔或卡槽，安装时间≤2小时，减少设备停机损失。
1.Product Positioning
Category:
METSO A413139 belongs to mechanical transmission or wear-resistant spare parts,which may involve crusher linings,screens,conveyor belt rollers,gearbox bearings and other parts.The specific needs to be further confirmed in combination with the equipment model(such as Metso Nordberg®C series cone crusher,HP series jaw crusher).
Design goals:
High wear resistance:Adopt high chromium alloy,ceramic composite materials,etc.,to adapt to the crushing of high hardness ores(such as granite,iron ore).
Impact resistance:Through optimized structural design(such as thickened lining,reinforced ribs),it can withstand the impact of large pieces of materials and reduce the risk of breakage.
Compatibility:Strictly match the original equipment size and installation interface of Metso to ensure direct replacement without modification.
2.Technical parameters(example)
If A413139 is a crusher lining,typical parameters may be as follows:
Parameter category Detailed specifications
Material High chromium cast iron(Cr26-28%),hardness HRC≥58,impact resistance≥5J/cm²
Size Customized according to equipment model(such as diameter 1200mm,thickness 200mm,weight about 1.2 tons)
Surface treatment Quenching+tempering,surface roughness Ra≤6.3μm,reduce material adhesion
Applicable working conditions Feed particle size≤300mm,discharge particle size 10-50mm,processing capacity 200-500 tons/hour
Service life In medium hardness ores(such as limestone)can reach 8000-10000 hours
Note:The actual parameters must be based on Metso’s official technical documents or product labels.
3.Typical application scenarios
1.Mining crushing system
Cone crusher:
A413139 as a movable cone liner or a fixed cone liner,compared with manganese steel liner,has a 30%-50%higher wear resistance,reduces the frequency of shutdown and replacement,and is suitable for medium and fine crushing of iron ore and copper ore.
Jaw crusher:
If it is a jaw plate,a layered crushing design is adopted,with coarse crushing in the upper section and fine crushing in the lower section,which improves energy utilization and reduces energy consumption by 15%-20%.
2.Screening equipment
Vibrating screen mesh:
If A413139 is a polyurethane screen mesh,it has a self-cleaning function to prevent wet material clogging,and the screening efficiency is≥90%,which is suitable for the classification of coal and sand and gravel.
3.Conveying system
Roller or roller:
If it is a conveyor belt roller,it adopts a sealed bearing design with a protection level of IP65 to prevent dust intrusion,a service life of≥50,000 hours,and reduces the risk of belt deviation.
IV.Advantages and characteristics
1.Material and process advantages
High chromium alloy material:
Compared with traditional high manganese steel,the wear resistance is improved by 2-3 times,especially suitable for high hardness and high abrasive materials.
Precision casting process:
Adopt lost foam casting or V method casting to ensure dimensional accuracy of±1mm,reduce installation gap,and reduce operating noise.
2.Customized design
Modular structure:
Support block replacement(such as the crusher liner is divided into upper,middle and lower sections),reducing the cost of a single replacement.
Quick installation interface:
Reserve bolt holes or slots,installation time≤2 hours,reducing equipment downtime losses.
