  • Grinding effect on kaolinite-pyrophyllite-illite natural ...

    After grinding using the pure silicates, kaolinite, pyrophyllite and illite, it was found that the increase in intensity and sharpness of this exothermic effect was only associated with the presence of pyrophyllite in the natural mixture irrespective of the presence of kaolinite and/or illite, at least up to 325 min grinding. This effect
