Abstract

BROYEUR A L'ENERGIE FLUIDIQUE. UNE ZONE DE BROYAGE EST CREEE A UNE EXTREMITE D'UNE CUVE QUI EST SUBDIVISEE EN UNE ZONE DE VEINE CENTRALE ET UNE ZONE PERIPHERIQUE ANNULAIRE. UN FLUIDE TRANSPORTEUR EST INJECTE DANS LA ZONE DE BROYAGE DE MANIERE QU'IL CREE UN TOURBILLON VERTICAL 44 DANS LA ZONE DE LA VEINE CENTRALE. UNE PREMIERE PARTIE DU FLUX DU TOURBILLON EST REMISE EN CIRCULATION A CONTRE-COURANT 46 DANS LA ZONE ANNULAIRE QUI ENTOURE LA ZONE CENTRALE DE MANIERE A CREER UNE INTERFACE A L'INTERIEUR DE LA ZONE DE BROYAGE. UNE SECONDE PARTIEDU FLUIDE EST DECHARGEE PAR UN PASSACE CENTRAL 26 A L'AUTRE EXTREMITE DE LA CUVE. LA SUBSTANCE PARTICULAIRE EST INTRODUITE DANS LE FLUX REMIS EN CIRCULATION DE MANIERE QU'ELLE SOIT FRACTIONNEE DANS LA ZONE DE BROYAGE. CETTE SUBSTANCE SUBIT UNE CLASSIFICATION DANS LE TOURBILLON PAR CENTRIFUGATION, LES PARTICULES GROSSIERES ETANT REMISES EN CIRCULATION. APPLICATION PAR EXEMPLE A LA REDUCTION DE CHARBON PULVERULENT EN POUDRE.
