Ball mill trunnion is an important part to load the mill rotary body. The neck that connected to bearing liner and the circular that connected to mill shell shouldn't cast with defects, such as, pore and sand hole. The neck that connected to bearing liner should have polishing machining and make sure its precision and smoothness. So it has strict requirement for casting technology.
