Ball mills are normally operated at around 75 of critical speed so a mill with diameter 5 metres will turn at around 14 rpm The mill is usually divided into at least two chambers allowing the use of different sizes of grinding media Large balls are used at the inlet to crush clinker nodules which can be over 25 mm in diameter .
After the initial comminution stages of crushing and/or SAG/AG milling the following grinding stages is usually carried out using steel charged ball or tower mills The impact of grinding using steel media can offset any benefits gained by improved liberation particularly as the target size decreases below 25 µm.
