Research Abstract	Development of a dry impact milling which could operate at sonic speed region was developed. It was found that micronization of particle down to single micron meter size at sonic speed region could be achieve which was imposable by the conventional dry impact milling. The milling mechanism was also analyzed by a numerical simulation.
