Tungsten carbide studs are core wear-resistant components of HPGR, mounted on two same size rollers surface, rollers rotate towards each other. to crush hard materials (rocks, ores, cement, coal)，Protect rollers from direct wear/impact by forcing abrasion to occur on the studs, enhance roller service life and efficiency through extreme hardness (8000–20,000+ hours life time)
