ABSTRACT:
A method for the reduction of the velocity of dispersions of fine particles in gas is described, in which the dispersion is divided into a plurality of mass flows M which are conveyed each to a subsonic diffuser to reduce the velocity from V.sub.1 to V.sub.2, wherein the product of mass flow M and density velocity ration S.sub.1 V.sub.1 /S.sub.2 V.sub.2 is less than 10 kg/sec.
The method is particularly useful in the manufacture of mineral wool, where the mineral wool fibers are first obtained being dispersed in a high velocity gas stream.
