The mill trunnion is an important part of the ball mill that carries the rotation of the ball mill barrel. It mainly plays the role of supporting and connecting the cylinder in the whole machine, and it is the in and out the channel of the material. The fillet at the root of the end plate of the ball mill trunnion is the stress concentration part, which is prone to blisters, pores, and micro-crack defects during casting. Therefore, the casting quality is extremely demanding.

We start by selecting high-grade steel, which is then cast using precise mold techniques to achieve the required shape and structural integrity. The casting process is followed by heat treatment to enhance the trunnion’s strength and resistance to wear and fatigue.
