ball mill head casting process

The first step: Simulation and modeling

Before casting, numerically simulate the casting process by CAE software to analyze the molding process, predict and optimize quality of ball mill head.

The second step: pouring and heat treatment

Sample the hot metal and perform the spectral analysis. After qualification, the pouring shall be carried out according to the principle of "low temperature and quick casting", and the pouring time and temperature shall be recorded.

The third step: Flaw detection, finishing

Finally, cut the pouring riser and burr etc. CHAENG has professional mechanical polishing teams and large-scale blasting apparatus, which can effectively improve the appearance quality of ball mill cover, to meet customer’s requirements on surface finish. Moreover CHAENG take use of advanced detection equipment for non-destructive testing to ensure the internal quality.
