Surface modification, size reduction and the improvement of energy efficiency were achieved simultaneously by using organic additives during continuous grinding with a commercial disintegrator (Cosmomizer, Nara Machinery). Triethanol amine(TEA) and toluene solution of stearic acid (SA) in varying concentrations were used as additives. While the organophilization of limestone with SA was detected, the addition of TEA caused the opposite effect. The adhesion of TEA to the limestone was tighter when it was used as a grinding aid than when it was simply added through impregnation. This was suspeted to be the result of a tribochemical reaction.
