A granulation process wherein a liquid is sprayed into a prilling tower (1) by means of a rotating prilling bucket (15) having a perforated side wall (15a), and the liquid jets exiting said perforated side wall are subjected to a vibrating action according to the axial direction (A-A) of the prilling tower (1), while the remaining liquid mass inside the bucket is kept substantially free from said vibrating action. A suitable apparatus is also disclosed, wherein the peripheral side wall (15a) of the prilling bucket (15) is connected to vibration imparting means and has a flexible connection with the frame (15b, 15c) of the bucket.
L'invention concerne un procédé de granulation qui consiste à pulvériser un liquide dans une tour de grelonage (1) au moyen d'un godet de grelonage rotatif (15) dont une paroi latérale (15a) est perforée, et à soumettre les jets de liquide sortant par ladite paroi latérale perforée à une action vibratoire selon la direction axiale (A-A) de la tour de grelonage (1), tandis que le reste de la masse liquide à l'intérieur du godet est maintenue sensiblement exempte de ladite action vibratoire. L'invention concerne également un appareil approprié, la paroi latérale périphérique (15a) du godet de grelonage (15) étant reliée à un dispositif produisant des vibrations et comportant une connexion flexible avec le bâti (15b, 15c) du godet.
