The effect of mechanical activation methods on the properties of local clays and waste bentonites

Abstract

One of the most important indicators of mechanical activation of clay minerals is the effect of activation time on the strength of the mixture. One of the most important parameters in the preparation of drilling fluid based on clays is their ability to swell, and the effect on the swelling of clays during mechanical activation was studied. One of the most important parameters of clays used in the preparation of drilling fluids resistant to thermomechanical effects is their colloidal index. Therefore, the effect of mechanical activation time on the colloidal index of these clays was studied. The method of activation of bentonites and analysis of their rheological parameters was studied. In the process of mechanical activation of clays, their activation of chemical reagents created conditions for modifying the increased specific surface area of clay materials.
