Fault 1: The mining ball mill makes loud noise. Reason: One of the reasons for loud operating noise may be unbalanced load distribution in the mill. Uneven distribution of material may cause uneven grinding media wear or excessive vibration, resulting in additional noise. Another possible cause could be worn or damaged bearings, which can cause ...
