The effect of dry grinding on the morphology and structure of kaolin particles treated with potassium acetate (KAc) and dimethyl sulfoxide (DMSO) has been investigated. After treatment with KAc, the d -spacing of kaolin increased from 0.72 to 1.03, 1.30, and 1.38 nm due to the combined effects of humidity and orientation of KAc molecules.

The effects of dry grinding in a porcelain ball mill and a chrome steel ring mill on the structure and morphology of talc and kaolinite minerals and mixtures have been studied. It is well known that ground talc is easier to make down as a suspension than unground talc and that it displays better rheological behaviour in the slurry.
