Abstract

Procédé de mélange d'au moins deux fluides à l'intérieur d'un tourbillon formé dans une chambre de révolution, où un fluide est introduit en amont pour former le tourbillon, l'autre fluide étant introduit dans le tourbillon et le mélange sortant tangentiellement en aval. Le second fluide est introduit axialement à l'extrémité aval, avec une vitesse axiale suffisante pour pénétrer à l'intérieur du tourbillon jusqu'à une zone de retournement et d'absorption dans le tourbillon. L'invention s'applique à la décarbonatation de farines de ciment, la farine étant alors mise en suspension dans l'un des fluides.
