In the previous paper, thirty two kinds of organic and inorganic powders were ball-milled and the rate of an increase of surface area by ball-milling was considered to depend on coherency of powder particles expressed as a function of surface energy, melting point, solubility in water, true density and so on. In this paper, influence of operational variables on the rate of an increase of surface area of sulfadimethoxine and white alundum by ball-milling was investigated.
