2002-1-1  The motion of grinding media inside a stirred mill changed considerably by varying the impeller speed and type. Three distinct regions were identified with a separate type of motion in each region. It was hypothesised that different forms of breakage occur in these different regions and change in these regions would affect the product size distribution.
