FINE PARTICLES MIXTURE PRODUCTION METHOD Russian patent published in 2017 - IPC B01F3/18 B22F9/14 

FIELD: metallurgy.

SUBSTANCE: method is described of producing a mixture of particles of different particle size and/or chemical composition, in which particles of different particle size and/or chemical composition are obtained from separate sources by their dispersion in the working environment by pulses of electric current, for which each corresponding particle source is positioned above the vessel or a container with working fluid. In the process of particles obtaining, their packing is carried out which essentially represents particle mixing process, and the desired distribution of particles of different particle size and/or chemical composition, and the ratio between them are prepared by adding to each particle source of certain number of pulses per time unit and energy deposited into pulse.

EFFECT: obtaining increased uniformity of mixture that includes particles with a predetermined particle size or chemical composition and a predetermined concentration.
