PROBLEM TO BE SOLVED: To provide a technology capable of being applied to any powdery raw material regardless of solvent solubility (water solubility, insolubility or the like) of the powdery raw material in a wet granulation for forming powdery granule particles, rapidly improving granulation efficiency and largely reducing the used amount of a binder, and to provide a technology largely reducing time necessary for a granulation process and a drying process, and markedly suppressing production cost and quality deterioration of granules.SOLUTION: There is provided a wet granulation method for forming powdery granules including (A) a process of charging a powdery raw material, (B) a process of induction charging a binder liquid drop in a reverse polarity to the powdery raw material, and (C) a process of granulating by contacting the powdery obtained in the (A) process and the binder liquid drop obtained in the process (B) to form the powdery granules. |
