grinding of kaolinite

Aggregation mechanism of colloidal kaolinite in aqueous
Sep 21 2020 In this study the effect of surfactants and electrolytes on stability of kaolinite dispersions was analyzed by measuring suspension transmittance zeta potential and adsorption. It was experimentally found that the compression of kaolinite electric double layer caused by NaCl addition may reduce the electrostatic repulse force to facilitate the aggregation of

A spectroscopic study of mechanochemically activated
However the greatest demand for kaolinite is in the paper industry where it is used to produce glossy paper such as those in magazines 3 . The wide industrial application of kaolinite depends on the ability to modify its properties for other uses. One such method is the mechanochemical activation of kaolinite through dry or wet grinding.

Study of Mechanical Force on Coal Gangue ..
The property of raw kaolinite coal gangue is very stable and reactivity of kaolinite coal gangue is enhanced by mechanical force. The SEM XRD and IR were used to analyze mechanochemical changes during kaolinite type coal gangue grinding. The results showed that mechanical force plays a dominant role in the enhanced reactivity by inducing dehydration reactions the lattice
