Ball millingis a size reductiontechniquethat uses media in a rotating cylindrical chamber tomillmaterials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by ...

Jan 11, 2016· 8. A ball mill also known as pebble mill or tumbling mill is amilling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
