FIELD: process engineering.SUBSTANCE: invention relates to nanotechnology, particularly, to grinding of various particles. Proposed device comprises housing with intake chamber equipped with peripheral stock feed pipe and aligned supersonic nozzle, working gas feed pipe, mixing chamber, diffuser, separator, adjustment body arranged coaxially behind supersonic nozzle throat and composed of a cone or a needle. Note here that nozzle inner surface has rough edges their height making 0.1-0.6 of nozzle neck diameter. Rough edges may be made on spiral path or at the angle to supersonic nozzle inner surface.EFFECT: grinding of various materials to nano sizes, particle surface processing by surfactants.3 cl, 3 dwg, 1 tbl |
