Description

Wet grinding of kaolin was carried out mechanically in water, by using a centrifugal rotating.type ball mill.<BR>In grinding operation, the following three conditions were used : (1) four different rotating numbers of ball mill, (2) five different alumina ball amounts, and (3) five different amounts of kaolin.<BR>Stainless steel modified-kaolin obtained was examined by X-ray analysis, zeta potential, and scanning electron microscopy.<BR>From the above experimental data, the kinetic mechanism in wet grinding of kaolin in water was discussed and the following facts were found out : <BR>(1) Zeta potential measurement would be useful as the systematic evaluation for both the grinding degree of kaolin and content of stainless steel powder on kaolin surface.<BR>(2) The proposed analytical methods I and II were recognized to be applicable for the evaluation of kinetic mechanism in wet grinding of kaolin by zeta potential.
