- kaolin grinding activator
it has been found that mechanochemical activation (e.g., dry grinding) of kaolinites can considerably increase the surface area, ion-exchange capacity, crystal structural deformation and amorphization, and solubility in acid and results in a progressive lowering of dehydroxylation temperature and intercalation reactivity ( kelley and jenny, 1936, …

Mechanical activation is a well-known technique in kaolin mineral preparation technology that was applied in ceramics. Haase [ 38] and Juhasz [ 39] focused on the morphological and structural changes of kaolin due to grinding. Later, this technique attracted much attention in the study of alkali activated geopolymers.

Ultra-fine grinding of the filter cake of kaolin (moisture content 23.80%) was conducted using the steam jet milling system. Dehydration of the ground material was caused by the high-speed superheated steam flow. As a result, the moisture contents of ground products were ~1%, thereby meeting the requirement for moisture content M ≤ 2%.

Also the grinding produces the amorphization of kaolin [8], by means of delaminating [9,10]. Acid activation has long been known as a preparation method for porous materials. In general, the acid solution dissolves the octahedral sheets of the clay and produces a significant modification over the tetrahedral sheets [11].
