The Process Lline of Production:
FAQ:
1.Q: Can you tell me the key factors which can decide the quality of the grinding balls?
A: They are the raw material, the strict process control,the hardness, the impact toughness, especially the raw material and the heat treatment.
2.Q:Can I see the difference just from the surface of the balls?
A: In general, you can not see the obvious difference from the surface of the balls.
3.Q: How can I make sure you are a reputable supplier?
A: Actually, there is no need to have any doubts about our reputation.High quality products,high
quality service and own research development manufacturing make our reputation.
We believe that corporate reputation is the most important principle for a company to exist.
