Application of Tungsten carbide tire studs/carbide tire pins/carbide tire stud spikes

 

High Pressure Grinding Roller is an energy-efficient crushing equipment of new technologies, widely used in grinding cement clinker,limestone,bauxite,iron ore.. High performance of carbide stud extends the life of High Pressure Grinding Roller. Zhuzhou Mingri provide quality carbide studs with good wear resistance and high compressive strength, can satisfy the requirements of different conditions.

 

Our Advantages:

1.Hemispherical top, protect the studs from being destroyed by stress concentration.

2.Round edges, protect the stubs 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 below are exclusive grades we developed for rolling machine. Good wear resistance and high strength are suitable for metal smashing with high working efficiency. Lifetime of carbide stud is over 8000-10000 hrs iron ore and 25000hrs for cement.
