ABSTRACT
Grinding a solid material is an important operation to reduce its size or to increase the surface area. Fine grinding would bring mechanical activation, leading to their agglomerations and mechanochemical phenomena such as phase transformation and modification of surface property have appeared in fine grinding, especially dry systems. The grinding of a solid is to reduce its particle size, and this phenomena are triggered by a mill device. One of the features of a ground product is to have a wide size distribution of irregular shaped particles. The size distribution in the single particle crushing is derived by applying a stochastic theory by J. J. Gilvarry, A. M. Gaudin and T. P. Meloy, or S. R. Broadbent and T. G. Callcott. F. C. Bond suggests that any comminution process would be an intermediate stage in the breakdown of a particle of infinite size to an infinite number of particles of zero size.
