“…(13, 19, 36, 81, 85, 109). Kukolev et al (70,71) found that with the use of organosilicone at concentrations of 0.005% in the grinding of alumina it is possible to reduce the time required for a given amount of size reduction by a factor of 4 in the case of ball milling and by a factor of 6 in the case of vibratory milling. Use of additives during dry grinding is very common in the cement industry.…”

The past reports in the literature on the effects that the physical and chemical nature of the environment has on such comminution processes as grinding and drilling are reviewed. The two major mechanisms put forward to explain certain commercially important beneficial effects of additives during grinding are the Rehbinder's mechanism based on adsorption-induced surface energy changes and Westwood's mechanism based on adsorption-induced mobility of near-surface dislocations. The mechanisms are discussed in the light of the available data in literature and critically reviewed. Literature data for this purpose has been of limited use because of the lack of control of important system variables during past comminution experiments.
