Recommended wear part materials for crushers processing high-hardness copper ore

High-hardness copper ores, such as porphyry copper with quartz veining, cause severe abrasive wear on jaw plates, mantle liners, and concave liners. Selecting the recommended wear part materials for crushers processing high-hardness copper ore is essential to minimize downtime and maintain product quality. OCP Machinery has developed a range of advanced wear materials based on 40 years of metallurgical research. For jaw crushers, we recommend high manganese steel grades Mn13Cr2 (for moderate impact) and Mn18Cr2 (for high impact and heavy abrasion). For cone crushers, OCP offers martensitic steel (hardness 550-600 HB) and chromium-molybdenum white iron (650-700 HB) for the highest abrasion resistance. In addition, we supply bimetal composite liners – a tough manganese steel backing with a ceramic or carbide-embedded wear layer – which can last 2.5 times longer than standard Mn18. The recommended wear part materials for crushers processing high-hardness copper ore also depend on the feed size and crushing stage. For primary crushing, high toughness is prioritized; for fine crushing, high hardness is key.

In actual operation, wear parts experience both abrasion (from quartz particles) and impact (from falling boulders). OCP’s metallurgists analyze your copper ore using a modified ASTM G65 test to determine the abrasion index (Ai). Based on the Ai value, we produce a wear part with an optimized hardness-toughness balance. For a copper mine in Peru with Ai = 0.8 (very high abrasion), OCP supplied jaw plates made of Mn18Cr2 with added titanium carbide particles, achieving 7,500 hours of life compared to 4,200 hours from the previous supplier. The recommended wear part materials for crushers processing high-hardness copper ore also include our “X-Rail” material for gyratory crusher mantles, which has a graded hardness profile – harder at the bottom where abrasion is greatest. OCP’s custom capability means we can cast wear parts to match your exact crusher model, even for non-OCP brands. Our direct factory pricing reduces your consumables cost by 15-20% because there are no intermediaries. Environmentally, OCP uses electric arc furnace melting and recycles used liners into new castings, achieving 95% material reuse.

OCP’s 40 years of field data has created a material selection matrix covering over 200 copper ore types. For a recent project in Arizona, USA, the mine was experiencing frequent liner changes every 600 hours. OCP recommended bimetal composite concaves and increased liner life to 1,800 hours – a 200% improvement. We also offer wear part performance guarantees: if our recommended material does not achieve the predicted life, we replace it free of charge.
