Title (EN) FLUIDIZED GRANULATOR
(FR) GRANULATEUR A FLUIDISATION
Abstract:
(EN) In a fluidized granulator made of steel sheet in accordance with the prior art, powder having high hygroscopicity is likely to cause blocking. Furthermore clogging is likely to occur in a bag filter. According to the present invention the outer walls of the granulator are made of a porous film in place of steel sheet of the conventional apparatus to eliminate the problems described above. This fluidized granulator can produce granules or coated powder particles by spraying water, a binder solution or a coating solution while powder is kept in a fluidized state.
(FR) Dans un granulateur à fluidisation réalisé en tôle d'acier conformément à la technique antérieure, la poudre ayant une hygroscopicité élevée peut être à l'origine de blocages. Il est en outre probable que l'engorgement ait lieu dans un filtre en forme de sac. Selon la présente invention, les parois extérieures du granulateur sont constituées d'une couche mince poreuse, à la place de la tôle d'acier de l'appareil classique, afin d'éliminer les problèmes précités. Ce granulateur à fluidisation peut produire des granules ou des particules de poudre enrobées en vaporisant de l'eau, une solution liante ou une solution d'enrobage, tandis que la poudre est maintenue dans un état de fluidisation.
