Read MoreWith dry grinding, these mills often work in a closed cycle. A scheme of the conical ball mill supplied with an air separator is shown in Fig. 2.13. Air is fed to the mill by means of a fan. Carried off by air currents, the product arrives at the air separator, from which the coarse particles are returned by gravity via a tube into the mill.

Read MoreMar 31, 2008 The critical speed (rpm) is given by nC = 42.29 √d, where d is the internal diameter in metres. 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.
