7. Grinding balls Production process
Forged balls are forged by air hammer after being heated by electric furnace.
Cast Balls and cylpebs are melted in electric furnace and poured into moulds after scientific proportioning. High chromium balls and cylpebs are also processed by oil quenching.
8. The difference of the forged ball and cast ball
Different production line
Different raw material
Different chemical element
Different core hardness and core hardness
9. How to choose the material
According to the different customer need and usage.
According to the ball mill size, dry grinding or wet grinding. We can recommend you the most suitable products.
10. Quality Control
Factory test
Grinding cylpebs test is an very important step. Real-time detection will be carried out in the production process. Cylpebs 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 cylpebs
The third party test
According to the customer different demand, cylpebs can be tested by any third party.
11. Packing
Cylpebs are usually packed in container bags and steel drums, it can also be customized according to different customer needs.
