Kinetics of fine wet grinding of zeolite in a steel ball ...

Feb 16, 2009  As seen in Fig. 6, the κ values for wet grinding of zeolite decreased with the equation represented in the figure as the grinding time increased. In the case of dry grinding, the slowing-down factor decreased again, but this decrease was sharper after 16 min of grinding time. (10) κ = d θ / d t. Download : Download full-size image; Fig. 4.

Synthesis of zeolites from mechanically activated kaolin ...

Jun 01, 1990  Mechanochemical phenomena in solids account for this kind of grinding [6,7]. In this paper, it is shown that kaolinite, the structure of which has been modified by grinding, is reactive for zeolite synthesis, generating in some cases products similar to those obtained when kaolinite undergoes thermal activation.

Zeolite - Wikipedia

Zeolites are microporous, aluminosilicate minerals commonly used as commercial adsorbents and catalysts. The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt, who observed that rapidly heating the material, believed to have been stilbite, produced large amounts of steam from water that had been adsorbed by the material.
