ZW ball mill ball production line:
Forged ball
1) Traditional Forged
Raw material →Cutting →Heating → Water quenching → Tempering
2) Auto Hot Rolling
Raw material →Hot Rolling Mill → Water Quenching → Tempering
Cast Ball
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.
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
6. 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.
ZW Grinding Ball quality control:
1) Raw material: Size, Chemcial elements, Microstructure quality control (LAIWU STEEL)
2) Production Technical: Cutting Size, Heating Temperature, Quenching Technical, Tempering control.
3) Grinding Balls : Hardness, Size, Chemcial elements, Breakage Rate Checking
4) Thrid-Pary: SGS, BV ISO, TUV, COTECNA, AsiaInspection etc.
