As the high efficiency crushing rate and low energy consumption of high pressure roller presses gain widespread market recognition, carbide pin -crucial for ensuring optimal roller press operation -are seeing increasingly broad application.
Jetvision provides carbide stud HPGR for roller press machine tailored to diverse customer operating environments.
Carbide studs are cylindrical or slightly tapered wear-resistant components made from cemented carbide (tungsten steel). Typically installed via interference fit or brazing onto equipment working surfaces, they serve as the“frontline fortress” against abrasion.
Their core characteristics include: extremely high hardness (HRA 85-92), outstanding wear resistance, and moderate impact toughness.
Due to the abrasive nature of ore and the effectiveness of ore crushing, carbide HPGR studs face stringent demands. From a transmission mechanism perspective, driving motors with torque output rather than speed output more effectively reduces roller surface wear rates. Besides strictly removing iron from new feedstock, maximum feed particle size and size distribution must be strictly controlled, with roller pressure and power appropriately matched. If the pin base surface is damaged, a wear resistant layer can form automatically. For significant pin damage, replacement, surrounding pin reinforcement, or weld overlay repair is required. Large-scale detachment of pins along with the base is critical, necessitating strict manufacturing standards for forging quality, heat treatment processes, and assembly tolerances between body bores and pins.
Jetvision's premium features maximize resistance to such issues:
1. Radius chamfers on edges prevent localized damage during production, transport, installation, and operation;
2. Overpressure sintering ensures high product density and strength;
3. Special processes eliminate residual surface stresses while enhancing surface hardness.
Carbide studs represent a classic“point-to-surface protection” wear resistant solution. By strategically applying the hardest material where needed most, they significantly extend the service life of heavy equipment in harsh environments at an exceptional cost-performance ratio, serving as a vital component of modern industrial wear-resistant technology.
