HPGR Tungsten Carbide Studs For Rolling Machine , Hard Rock
Crushing Wear Resistant Surface
Specification
1. Hemispherical top, protect the HPGR carbide studs from being
destroyed by stress concentration.
2. Round edges, protect the HPGR carbide studs being damaged during production, transportation, installment
and using.
3. HIP sintering ensure good compactness and high toughness for the
products.
4. Special technology to eliminate the surface stress after surface
grinding, and increase the surface hardness at the same time.
5. Grease used on surface of the products to avoid oxidization.

Grades above are exclusive grade we developed for rolling machine.
Good wear resistance and high strength are suitable for metal
smashing with high working efficiency. Lifetime of HPGR carbide
studs is over 8000-10000 hrs.
Dimensions can be done by client's drawing.
Application
If rolling machine uses HPGR carbide studs, it gets high
density,high strength and good impacting property. Lifetime of
Cemented carbide stud is over 10 times more than surfacing
material.
