7. forged steel grinding media 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

① Different production line

② Different raw material

③ Different chemical element

④ Different core hardness and core hardness

9. How to choose the material

① According to the different customer need and usage.

② According to the ball mill size, dry grinding or wet grinding. We can recommend you the most suitable products.
