Abstract

Procedure for making strongly diluted and homogeneous mixtures, in particular for mixing water fibers, fibers and air or other fluids for the paper industry or the manufacture of non-woven fabric, characterized in that in a first stage, a mixture is produced that presents a fractionation regulate one of the fluids in the other and because in a second state this mixture is injected, in a dilution chamber, in the form of multiple jets at high speed, and the homogeneous mixture thus constituted can be sent to this dilution chamber directly for use, or if the dilution degree is not sufficient, it can be sent to a second stage identical to the one just described.
