Description of Good abrasion resistance for HPGR tungsten cemented carbide stud tips pins
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 Mingri provide quality carbide stub with good wear resistance and high compressive strength, can satisfy the requirements of different conditions.
- 100% virgin raw materials, stable chemical properties, long life circle.
- High hardness, good hardness, excellent wear-resistance.
- Various sizes and full types available
- Products can be customized upon requirement
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.

Production Process of Good abrasion resistance for HPGR tungsten cemented carbide stud tips pins
To ensure the quality and the requirements of the drawings can be met before mass production
1st:, Start to prepare the RTP powder as per customer’s requirement with our wet-grinding machine
2nd, Before mass production, do a trial pressing and sintering using mould,
3rd, Check the appearances and the sizes of the samples with micrometer, projectors etc.
Test process of Good abrasion resistance for HPGR tungsten cemented carbide stud tips pins
1st,Mass production, press the raw materials to shape blanks,
Notes: all carbide stud pins blanks must be passed by semi finished inspection
2nd,Sinter blanks to finish (HIP) and finished products inspection,
Notes:10 sets of vacuum sintering furnace and 2set of HIP in the factory ensure the best quality and production capacity.
3rd,Cleaning/tumbling to make the carbide stud pins clean and nice surface.
Packing of Good abrasion resistance for HPGR tungsten cemented carbide stud tips pins
step 1, wrapped carbide stud pinsr in paper to avoid carbide stud pins be broken
step 2, put the carbide stud pins in inner small carton box
step 3, put the inner box into outer carton and fill the carton with foamed plastic
step 4, wrap the carton with packaging tape
