In demanding mineral processing applications, HPGR (High Pressure Grinding Roll) equipment is continuously exposed to extreme abrasion, high impact forces, and heavy material pressure. Traditional wear materials often suffer from rapid degradation, frequent replacement, and increased maintenance costs. Old Craftsman abrasion resistant HPGR carbide studs and edge blocks are engineered with premium tungsten carbide materials to provide exceptional wear resistance, impact strength, and extended service life for HPGR rollers operating in harsh mining environments.
Our tungsten carbide HPGR studs and edge blocks are widely used in cement, iron ore, copper ore, gold ore, and other mineral processing industries. The specially optimized carbide grade combines high hardness with excellent toughness, helping protect the roller surface from severe abrasive wear caused by hard minerals and continuous crushing cycles.
The carbide studs are vacuum brazed or precision assembled into the roller body to ensure strong bonding performance and reliable operation. Compared with conventional wear solutions, tungsten carbide components can significantly reduce downtime caused by frequent wear replacement, improve grinding efficiency, and lower overall operating costs.
HPGR carbide edge blocks are designed to protect the vulnerable roller edges, where stress concentration and material impact are usually higher. Their superior abrasion resistance helps prevent edge damage, maintain consistent roller performance, and extend the service life of expensive HPGR equipment.
Manufactured by Old Craftsman Precision Alloy, our HPGR wear components are produced under strict quality control, including powder selection, precision sintering, HIP treatment, and surface finishing. Customized sizes, grades, and designs are available according to different HPGR models and operating conditions.
