The grinding produces a progressive increase of the accessible sites for NI-I4+ and Naions. Okuda et al. (1969) reported that the CEC of talc increased from 0.4 meq/100 g to 1.5 meq/100 g when the surface is incremented up to 20 m2/g by grinding; in this study, the mineral remained unchanged with respect to its crystallinity (i.e. no ...

Talc particulates were ground by a high-speed rotor mixer without grinding media (beads) under atmospheric condition in order to evaluate the performance of the mixer. The median diameter of the ground sample decreases with an increase in both rotational speeds of the rotor and the vessel, and with a decrease in the clearance in the working space.
