Electrostatic processes at cement grinding

The article analyzes the electrostatic processes at cement grinding as cement that comes out of the mill has a considerable electric potential of positive polarity. It is shown that, at grinding, surfactants and the ECOFOR device demonstrate basically the same antistatic properties. The article also describes the mechanism of electrophysical action of that device, which differs from that of surfactants, as it is based on the assumptions of the theory of dislocations and physics of the surface.
