A pharmaceutical ball mill is a type of grinder used to grind and blend materials while manufacturing various dosage forms. The size reduction is done by impact as the balls drop from near the top of the shell. Ball mills are used primarily for singlestage fine grinding, regrinding, and as the second stage in twostage grinding circuits.

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 ...

There are three types of grinding media that are commonly used in ball mills: • steel and other metal balls; • metal cylindrical bodies called cylpebs; • ceramic balls with regular or high density. Steel and other metal balls are the most frequently used grinding media with sizes of the balls ranging from 10 to 150 mm in diameter [30].
