A plurality of fluent substances are combined in a distributor (11, 37) and caused to flow in a continuous, pressurized stream through a mixing zone (13, 13', 57) wherein the substances are intimately mixed by turbulent dispersion effected by a series of conically shaped surfaces (24, 27; 62, 64) and alternate restrictions (25, 63) and expansion chambers (28, 65). While various fluent substances may be advantageously mixed, a typical utility is for effecting a thorough air binding of ink particles to attain efficient foaming (29) in the deinking of reconstituted printed paper slurry.
