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  

advantages  

1. Our company adopts special heat treatment process to improve the hardness and impact resistance of ball mill trunnion.  

2, forward cast steel production of ball mill trunnion using high strength steel.  Before casting, our professional engineers first optimized the technical structure of the trunnion according to the operation characteristics of the ball mill.  This can not only ensure the stability of parts in long time operation, but also prolong the service life of parts.  

3, forward casting steel casting steel parts have strong production capacity of casting steel parts, can provide a large number of castings, casting cycle is short.
