Process for producing mineral wool fibers while reducing the velocity of flowing media

摘要

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 V1 to V2, wherein the product of mass flow M and density velocity ration S1 V1/S2 V2 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.
