The trunnion head is the main component of the ball mill. Due to the change in wall thickness, shrinkage cavity, and shrinkage porosity defects are likely to occur at the lower small flange journal and the upper bell mouth journal, which seriously affects product quality, which has become a restriction on the production and the main problem of delayed delivery. 

However, CHAENG has increased its innovation in the production of ball mill trunnion heads. The ball mill trunnion head produced by it has a short casting period, long service life, and high product quality.

1. CHAENG uses special heat treatment technology to improve the hardness and enhance the impact resistance of the ball mill trunnion head.

2. CHAENG has professional mechanical polishing teams and large-scale blasting apparatus, which can effectively improve the appearance quality of ball mill head, to meet customers’ requirements on surface finish.

3. Optimized the technical structure of ball mill trunnion according to running characteristics of ball mill, to guarantee the stability of the trunnion during long time running, but and prolong its working life.

4. Great Wall Steel Casting has strong casting capability, and it can provide casting parts with good quality and a short production period.
