Feb 01 1987 the oxide particles are usually round or spherical m shape and are all less than 60 pin in size with a mean diameter of3-4pm by contrast ball mills yield an oxide with 60 - 70 wtpbo an apparent density of 15 g cm-3 and an acid absorption of around 200 mg hzs04 per gram of oxide.
Hence at the same rotational speed and ball size the oxide ball with the lowest density will generate the lowest collision energy.
