    Stress imposed on particles is result of the centrifugal forces of grinding media being agitated at high speed. In this situation stress intensity is proportional to the cub of media size, stirrer speed velocity squared and the difference between the media and slurry density (Kwade, 1996). In low speed vertical stirred mills (LSV) such as the
