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
