12%The effect of dry grinding of kaolin minerals by a mechanical mortar was examined by x-ray, thermal, and electron microscopic methods. Base exchange capacity and apparent density were also measured. In the early stage of grinding, kaolin crystals cleave and fracture and then split into fine crystals which are considered unit crystallites.

The dry grinding achieves a better refinement than wet grinding because the buffering of the liquid can weaken the mechanical action force, and the layered clay shears and splits along the cleavage plane during wet grinding. The D50 of kaolin clay slurry decreases from 2.479 to 1.619 μm after wet grinding, which shows a good refinement.
