Kaolin is used in paper filler and coatings, in cosmetics, in ceramics as well as ceramic proppants, in addition to many filler or absorbent applications. Pure kaolin is a relatively soft mineral, with a Mohs hardness of 2 – 2.5. However, mined kaolinite may have a minor portion of abrasive impurities such as quartz / sand.

Dry grinding of pyrophyllite (Hillsboro, USA) has been studied by X-ray diffraction (XRD), specific surface area measurements (BET) and scanning electron microscopy (SEM). At the beginning of the grinding process, ... Juhasz, Z. (1980) Mechano-chemical activation of kaolin minerals.

Dry grinding of kaolin would greatly change the shape of the particles by rounding their edges leading to spherical structures. As was rightly explained by Horvath et al., mechanical activation caused the delamination of kaolinite and therefore the decomposition of its structure. The delamination process occurred with point heating.
