Media milling can be considered a modernized version of the ball mill . This technology, first developed by Liversidge and co-workers [76], [77], is a classical wet milling technique wherein a sufficiently concentrated dispersion of drug particles in an aqueous or non-aqueous liquid medium is subjected to a traditional ball milling operation ...
The ball mill grinds it for 10minutes, powered by a standby generator. After 10 minutes, the ground limestone is poured out and the walls of the ball mill, is cleared with the aid of the hand brush. The ground limestone is placed on the weighing machine where a mass of 420g which is our feed size is obtained.
Term ball mill Acronym n/a Category system Application GMD, RMD Definition Rotating drum used to reduce the size of raw material by the projection and the self-gravity of the material itself.

Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.
