Abstract: 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.
