ABSTRACT:
In a method of and an apparatus for producing a gas-solid free jet (7) of constant mass or volume flow rate, in which jet the solid particles having a particle size particularly smaller than 50 .mu.m are dispersed completely and uniformly, a consolidated or compressed solid particle mass flow (8) of constant density and constant cross section is produced with the aid of a rotating metering groove (2) and subsequently sucked entirely into a closed flow channel to be accelerated and dispersed in an injector (9). The resulting gas solid particle mixture is discharged out of the flow channel as a free jet (7). Dispersing, particularly of very fine particles (up to a few .mu.m) is promoted until practically complete by directing the gas-solid particle mixture against at least one impact surface (17), in particular against a plurality of obliquely disposed impact surfaces arranged offset in zig-zag fashion one behind the other so as to be impinged upon successively (impact surface cascade (15)) and only then discharging the mixture out of the flow channel.
