FAQ:
1.Q: Why is the price much different when I inquiry the same grinding balls from different factories? A: There are two main factors:
1.The raw material occupies a very important part in the price of the grinding balls. All of our
materials were purchased from the large state-owned steel factories, we will make sure the raw material’s quality of the balls from the first step;
2.The strict process control occupies another very important part in the price of the grinding balls.A variety of process equipment, process raw materials are strictly controlled to ensure and improve the process quality of products in our factory;
2.Q: How can I make sure your factory's products are in good quality?
A: Firstly, we warmly welcome the 3rd party test, such as the SGS to test our balls at random.
Secondly, you can pay a visit to our factory and you will be much impressed by our strict process control, premium products and scientific management.
