Popis: Samples of mechanically activated quartz sand powder were obtained by grinding on a planetary ball mill to different specific surface values (1200-3000 m2/kg). For these dispersed systems, the surface activity criterion (kS) was calculated as a value equal to the ratio of the free surface energy of the system to its total potential value (specific mass energy of atomization). It is established that the value of this criterion does not depend linearly on the time parameters of mechanical dispersion of the initial samples. The kS parameter is recommended for evaluating the effectiveness of the process of mechanical activation of rocks.
