Dec 30, 2017 The ball mill was shut down on June 28 for removal of the trunnion, liner and two part urethane. The presence of the urethane extended the job from the original six hours to 4 days. Preliminary discussions between engineers indicated that there were possibly as many as six (6) eroded areas that would be susceptible to cracking based on their visual comparison of eroded areas during their initial repair attempts.
Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.
Oct 28, 2015 What is the typical reason a ball mill trunnion needs to be replaced unexpectedly It is unclear if the trunnion damage was known ahead of time and planned for a change-out during the shell reline or if it was discovered during the reline work. While, not knowing if this is the feed or discharge end trunnion, there could be a number of.
A ball mill is a large cylindrical tube partially filled with steel balls. The ends of the steel cylinder are attached to trunnions that are supported on journal bearings. As the ball mill rotates, the steel balls in the cylinder rise up on the mill's inside surface and eventually tumble down to the bottom. The raw material is fed into the ball.
