    2020-9-24 · When mills are rotating at too fast a rate centrifuging will occur. Individual media are thrown clear of the media mass and move independently until they rejoin the charge at the bottom of the mill. Un-ground material is held with the centrifuging balls and result in uneven disintegration or dispersion.
