Effect of Dry Grinding on Kaolin Minerals SpringerLink

Feb 01, 1957  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. Such crystallites gradually change to a disordered ...

Dry and wet grinding effects of kaolinite on the formation of zeolite Na-A and Na-X in NaOH solution are fundamentally investigated. Intensive dry grinding causes the structural deformation of ...

Comparison of Dry Grinding Effect on Commercial Quartz ...

[20,21]. Since the major mineral constituents of natural kaolin are kaolinite and quartz, the effect of quartz content in the distortion of kaolinite induced by dry grinding was obvious. Being so far not well defined, some researchers found needful to study the influence of the co-presence of quartz, whether

of grinding, manual or mechanical, dry or wet, and the kind of the min-erals and salts. The wet grinding was made in the presence of water just wetting the clay-salt mixture. The dry or mechanical grinding was 3 to 5 times as efiective as the wet or manual grinding respectively, but caused considerable destruction of the crystal structure.
