三、典型应用场景
1.矿山破碎系统
圆锥破碎机：
D200175作为动锥衬板或定锥衬板，与传统锰钢衬板相比，耐磨性提升30%-50%，减少停机更换频率，适用于金矿、铁矿的中细碎。
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10%-15%。
颚式破碎机：
若为颚板，采用曲面破碎腔，增加物料破碎次数，提高产品粒度均匀性，适用于石灰石、煤炭的粗碎。
2.筛分设备
振动筛筛网：
若D200175为聚氨酯筛网，具有高弹性、耐油性，防止湿料堵塞，筛分效率≥90%，适用于砂石、尾矿的分级。
3.输送系统
托辊或滚筒：
若为输送带托辊，采用迷宫密封设计，防护等级IP67，防止粉尘和水侵入，使用寿命≥50,000小时，减少皮带跑偏风险。
1.Product Positioning
Category:
D200175 may be a wear-resistant lining of a crusher(such as a cone lining of a cone crusher,a jaw plate of a jaw crusher),a vibrating screen or a conveyor belt roller.The specific model needs to be further confirmed in combination with the equipment model(such as Metso Nordberg®GP series cone crusher,HP series jaw crusher).
Design goal:
Wear resistance:Use high-hardness alloy materials(such as high-chromium cast iron,cemented carbide)to adapt to the crushing of hard rocks such as iron ore and copper ore.
Impact resistance:Through thickened design,buffer structure or elastic material,it can withstand the impact of large pieces of material and reduce the risk of breakage.
Compatibility:Strictly match the size and installation interface of Metso’s original equipment,support direct replacement without modification.
2.Technical parameters(example)
If D200175 is a cone crusher mobile cone liner,the 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 the equipment model(such as diameter 1200mm,height 350mm,weight about 1.8 tons)
Surface treatment Laser cladding(LC)or high velocity flame spraying(HVOF),forming WC-Co hard alloy coating,thickness 0.2-0.4mm
Applicable working conditions Feed particle size≤300mm,discharge particle size 6-25mm,processing capacity 300-600 tons/hour
Service life In hard rock conditions(such as granite)can reach 5000-7000 hours
3.Typical application scenarios
1.Mining crushing system
Cone crusher:
D200175 as Compared with the traditional manganese steel liner,the wear resistance of the movable cone liner or the fixed cone liner is improved by 30%-50%,which reduces the frequency of shutdown and replacement,and is suitable for medium and fine crushing of gold and iron ores.
Layered crushing design:upper coarse crushing and lower fine crushing improves energy utilization and reduces energy consumption by 10%-15%.
Jaw crusher:
If it is a jaw plate,a curved crushing chamber is used to increase the number of material crushing times and improve the uniformity of product particle size.It is suitable for coarse crushing of limestone and coal.
2.Screening equipment
Vibrating screen mesh:
If D200175 is a polyurethane screen mesh,it has high elasticity and oil resistance,prevents wet material clogging,and the screening efficiency is≥90%.It is suitable for the classification of sand and gravel and tailings.
3.Conveying system
Rollers or rollers:
If it is a conveyor belt roller,it adopts a labyrinth seal design with a protection level of IP67 to prevent dust and water intrusion,with a service life of≥50,000 hours,reducing the risk of belt deviation.
