Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials 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

the rate of grinding in the planetary ball mill is known to be about 100 times greater than that in a tumbling ball mill and about 50 times greater than that in a stirred ball mill2 . Another result is given in Fig. 3 from which it is seen that even small glass beads with a low density can be used to grind hard materials

The Influence Of Magnesium Grain Size And Ball Milling. The influence of both mg grain size and ball milling time on the phase formation of mgb 2 tapes has been studied the finer grain sizes of mg powder under 45 m and the wellmilled condition above 8 h improve the j c value effectively it was found that the j c values of the mgb 2 tapes were consistent with the results of

2011 5 16 Grain size has a measurable effect on most mechanical properties. For exam ple at room temperature hardness yield strength tensile strength fatigue strength and impact strength all increase with decreasing grain size. Machinability is also affected rough machining favors coarse grain size while finish machining favors fine grain size.
