Mining machinery

Tungsten carbide (hard alloy), with its ultra-high hardness (HRA 85-93), wear resistance, impact resistance, and high-temperature wear resistance, precisely meets the stringent requirements of mining machinery for "high-intensity crushing, harsh geological erosion, and long-term heavy-load operation." It is widely used in core processes such as crushing, mining, and screening, and is a key material for improving equipment lifespan and operational efficiency. Specifically:

In the ore crushing process, tungsten carbide is the preferred material for core wear parts. Jaw plates and toggle plates of jaw crushers, crushing walls and jaw walls of cone crushers, and hammers and liners of impact crushers are all made of tungsten carbide inserts or integral tungsten carbide. Its wear resistance is 10-15 times that of ordinary high-manganese steel, capable of withstanding severe impacts and grinding from hard materials such as granite and iron ore, increasing component lifespan by 3-5 times and reducing downtime for replacement. The hammers of hammer crushers use a tungsten carbide composite structure, balancing high hardness and impact resistance to ensure stable crushing efficiency.

In mining and drilling operations, tungsten carbide plays a crucial role. The cutting teeth of coal mining machines and tunneling machines are made of fine-grained tungsten carbide, enabling efficient cutting of coal seams and rock strata, withstanding the wear and impact of complex underground geology, and reducing tooth wear. Drill bits and drill bits used in geological exploration and mining drilling, relying on the high rigidity and fatigue resistance of tungsten carbide, can penetrate hard rock formations, achieving drilling efficiency 2-3 times that of ordinary alloy drill bits, and significantly extending service life. The wear-resistant inserts of mining auger drill rods are also made of tungsten carbide, improving the wear resistance of the drill rod under heavy-load rotation.

In ore screening and conveying processes, tungsten carbide ensures stable equipment operation. The screen mesh and screen plates of the vibrating screen are made of tungsten carbide composite material, which has strong resistance to material erosion and wear, preventing the screen holes from clogging or deforming too quickly and extending the maintenance cycle of the screening equipment. The wear-resistant layers of the idlers and drums of the belt conveyor, as well as the linings of chutes and hoppers, are enhanced with tungsten carbide linings to reduce equipment wear during ore transportation and lower the risk of material jamming.

Furthermore, the valve cores and seats of the hydraulic system in mining machinery, as well as the wear-resistant inserts of transmission components such as gears and drive shafts, are all made of tungsten carbide. With its excellent dimensional stability and corrosion resistance, it is suitable for the harsh, humid, and dusty environment of mines, fully supporting the efficient, continuous, and low-wear operation of mining machinery.
