Abstract (en)

The mixer comprises a rotary shaft 7 passing through a stationary hopper 1, carrying a perforated rotating tray 3 and having, passing through it, a conduit 6 ending in a spraying nozzle 8, a spraying chamber 5 and a rotary assembly consisting of a stirrer 9 and a conical tray 10. <??>The rotary assembly is connected by arms 11 to the tray 3. A conical tray 10 dips into a mixing chamber 12 equipped with counter blades 13 and rotating in a direction opposite to that of the rotary assembly. <??>Permits an excellent impregnation in bulk by virtue of the intimate contact and of the mixing of the coated particles. <IMAGE>

Abstract (fr)

Le malaxeur comprend un arbre rotatif 7 traversant une trémie fixe 1, portant un plateau tournant perforé 3 et traversé par un conduit 6 se terminant par une buse de pulvérisation 8, une chambre de pulvérisation 5 et un ensemble rotatif composé d'un agitateur 9 et d'un plateau conique 10. L'ensemble rotatif est relié par des bras 11 au plateau 3. Un plateau conique 10 plonge dans une chambre de malaxage 12 munie de contre-pales 13 et tournant en sens inverse de l'ensemble rotatif. Permet une excellente imprégnation dans la masse grâce au contact intime et au malaxage des particules enrobées.
