12% Co Cemented Carbide HPGR Stud / Pins / Buttons for High Pressure Grinding Roller
High Pressure Grinding Roller is an energy-efficient crushing equipment of new technologies. High performance of carbide HPGR stud extends the life of High Pressure Grinding Roller. Zhuzhou Better provide quality carbide studs with good wear resistance and high compressive strength, can satisfy the requirements of different conditions.
The Wear parts of HPGR is mainly the Roller with Cemented Carbide Studs( or named Carbide Pins or Carbide Buttons).Tungsten carbide studs (or Carbide Buttons, Pins) have high toughness, high hardness and excellent wear-resistant performance. So the tool life of roller can be extended effectively.
Our cemented carbide HPGR studs pins are widely used in the below fields.
Grinding bulk material.
As pre grinding equipment before ball mill or form complex grinding system with ball mill in the field of mineral separation,
Widely used in grinding cement clinker,limestone,bauxite,iron ore.
