crushing of mineral particles by control of their kinetic

Jun 09, 2016 High kinetic stability can be achieved by fine grinding, but such a suspension could not be sufficiently fluid for the ore particles to move freely in their separation. On the other hand, an excess of coarse particles yields a high fluidity of the medium, but such a medium is not stable without a stirring device to prevent settling out.
