An attempt was made to prepare granules with high water content for semi-dry press forming with a stirring granulator. The agglomerate structure and compaction behavior of the granules were compared with those of spray-dried granules generally used for press forming. Dense granules containing water above 10% were obtained and showed high fluidity in comparison with the spray-dried granules. The obtained granules were more easily deformed and crushed at low forming pressure than spray-dried granules, because they contained large amount of water and had a loose agglomerate structure. Accordingly, the volume change in powder beds of the granules in pressing was larger than that of the spray-dried granules, resulting in high relative density of powder compacts at low pressure.
