In order to clarify the properties of wet powders which gave maximum granulating pressure in the preparation of ganules, compaction behavior, flow property, and plasticity of wet powders kneaded with various amounts of binder were investigated. It has become apparent that several characteristics curves indicating the properties of wet powder have a maximum or a flexion point at about the same amount of the hinder, and that the amount of a binder giving these points corresponds to that for maximum granulating pressure. Therefore, it can be presumed that the wet powder giving a maximum granulating pressure is in the plastic limit.
