The effects of several-hundred-hour mechanical-mortar dry grinding of kaolinite were studied by X-ray, thermal, electron microscopic and other methods. It has been found that there are two sorts of structural change in the process of dry grinding of kaolinite. One is the production of a non-crystalline substance attended by the disordering of the crystalline part, and the other is the ...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 dry grinding process is mostly used for ultra-fine grinding of hard kaolin into ultra-fine powder products to meet the requirements of users. The main equipment used in dry grinding includes Raymond mills, high-speed impact mills, vibration ball mills, stirring mills and air jet mills, among others, and they are often used to process ...In Kibushiclay, the time it takes to become amorphous by dry grinding is shorter than in the case of kaolinite. Consequently, the effects of dry grinding of kaolinite and kaolin mineral of fireclay type depend on the structural perfection of unit layers of the original kaolin minerals.
