The trunnion of the ball mill (hollow shaft of the ball mill) is an important part bearing the rotary body of the mill. The neck connected with the bearing bushing and the circle connected with the mill shell should not be cast with holes, sand holes and other defects. The bearing connected with the neck and bearing bushing should be polished to ensure its accuracy and smoothness.  Therefore, qianjin cast steel is one of the enterprises that can produce high quality ball mill trunnion in China

Ball mill trunnion parts:  

The trunnion and head of ball mill will bear great alternating stress during operation.  Although the trunnion is designed for unlimited life, there is always a risk of cracking due to small casting defects, wear on the inner surface of the trunnion, or other damage (such as cutting scars or welding in areas of high stress).  

To avoid premature failure of these important mill components, very high quality manufacturing procedures must be used.  Qianjin cast steel uses only a limited number of trunnion shafts produced by high quality foundries to ensure that the final quality reaches the highest standard.
