media, there is a tendency for segregation of the media in the mill. At a low rotational speed, the media tend to settle, leading an inhomogeneous distribution of media. On the other hand, at higher rotational speeds, a vortex is formed and the media are concen­ trated at the wall due to centrifugal forces. Therefore,
