The effect of dry grinding of kaolin minerMs 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 erystallites.
EFFECT OF DRY GRINDING ON KAOLIN MINERALS by Xray diffractometer traces made at various stages in the grinding of kaolinite are shown in Figs 1 and 2 and the data are also shown in Table 1 When kaolinite is ground it gradually assumes a moreandmore dis ordered structure that is the background increases as the intensity of the .
The dry grinding treatment can disaggregate the crystal bundles of palygorskite and is favorable to generate mesopores and micropores. The adsorption efficiencies of grinded palygorskite for methylene blue were enhanced owing to the availability of more shielded adsorption sites and increasing specific surface area, micropore volume and mesopore volume.
