6. Quality Control
① Factory test
Steel Grinding Balls test is an very important step. Real-time detection will be carried out in the production process. Balls produced in each shift will be sampled in large quantities and tested for size, hardness, chemical composition, drop test, core pulling and impact value to ensure the quality of steel balls.
② The third party test
According to the customer different demand, steel grinding balls can be tested by any third party.
7. Packing
Steel Grinding balls are usually packed in container bags and steel drums, it can also be customized according to different customer needs.
