Tungsten Carbide Studs for HPGR Rollers
High Pressure Grinding Roller is an energy-efficient crushing equipment of new technologies. High performance of carbide stud extends the life of High-Pressure-Grinding-Roller. Zhuzhou Hongtong provide quality carbide studs with good wear resistance and high compressive strength, which can satisfy the requirements of different conditions.Our HPGR bits are made with typical tungsten carbide, which ensure long wear life and consistent quality. This means lower operating costs, less down time for machine maintenance, and a more predictable wear life. Close attention is paid to quality control ensuring our bits fit properly. Our replacement HPGR bits are guaranteed to meet or exceed the OEM specification for fit, material grade and performance unless otherwise stated.

Manufacture characteristics of product
HPGR technology working principle is that two counter-rotating grinding rolls expose a column of material to high pressure, which is distributed across the gap between the rolls. Inter particle comminution is the HPGR specific grinding process in which material particles are crushed and ground within the compressed material bed and not by contact with the roll surface. Feed material can be smaller than the gap, which is an important distinction as compared to crushers.
