Abstract
L'invention a pour objet un procédé de granulation comprenant une étape de pré-granulation destinée à former un écoulement discontinu d'un métal liquide, sous forme d'un flux de gouttelettes, et une étape d'atomisation destinée à former des granules de métal solides par fragmentation et solidification des gouttelettes reçues sur un disque tournant refroidi. Un autre objet de l'invention est un système de granulation comprenant un creuset et un capillaire relié au creuset, et un dispositif de génération d'un écoulement discontinu de métal liquide en sortie du capillaire configuré pour former un flux de gouttelettes. Le système comprend également un disque tournant refroidi configuré pour recevoir le flux de gouttelettes, fragmenter et solidifier les gouttelettes de façon à former des granules de métal solides.
