The ball mill head is the collective name for the end cover of the cylinder and the trunnion. It sustains the rotation load of the entire mill body and grinding media, and continuously operates under the action of alternating stress. It is also the weakest link of the ball mill and the most difficult to control the manufacturing quality.
