Description Of Tungsten Carbide Stud Pin for HPGR
Tungsten Carbide Stud Pin for HPGR is a high-performance cylindrical wear element manufactured from tungsten carbide (WC) with a metallic cobalt binder through advanced powder metallurgy and HIP (Hot Isostatic Pressing) sintering processes. These studs are the core wear-resistant components of High Pressure Grinding Rolls (HPGR), mounted on the surface of two counter-rotating rollers to crush hard materials including rocks, ores, cement, and coal.
HPGR is an energy-efficient crushing equipment of new technologies, widely used in grinding cement clinker, limestone, bauxite, and iron ore. The carbide stud pin serves as the core component that provides high wear resistance and high compressive strength. The studs are inserted into the roller surface in a specific pattern, with the stud head protruding from the roller surface to form an effective crushing surface. During operation, the studs protect the roller body from direct wear and impact by absorbing the abrasion, significantly extending the service life of the HPGR equipment.
Tungsten carbide stud pins for HPGR are manufactured from 100% virgin raw materials, with high density (13.4–14.95 g/cm³), extreme hardness (HRA 85.5–90.8), and high transverse rupture strength (TRS up to 3,800 N/mm²). These properties enable the studs to withstand the severe impact and abrasive forces generated during high-pressure grinding operations.
Tungsten carbide stud pins are available in a comprehensive range of grades (YG11C, YG13C, YG15C, YG20, CZ11C, MH12, CG50, CK402, CZ18M, CZ20M, etc.), shapes (ball-headed, flat-headed), and sizes (outer diameter 5–22mm, height 20–70mm) to meet diverse crushing requirements across mining, cement, and metallurgical industries.
