PROBLEM TO BE SOLVED: To prevent a binding agent adhering to the inside of a binding agent-supplying part from dripping down from an opened part in an upper end of a storing part of the binding agent-supplying part, when a cover part is rotated to open an opening part of a container body, in a stirring granulator.SOLUTION: A stirring granulator comprises a binding agent-supplying part 5 for supplying a binding agent into a treating container. The binding agent-supplying part 5 has: a storing part 5a installed upright above a cover part of the treating container and storing the binding agent and a passage part 5b extending by passing through the cover part of the treating container, the passage part being used for supplying the binding agent stored in the storing part 5a to an inside of the container body of the treating container. The storing part 5a has an upper end 5d thereof opened, wherein the upper end 5d is provided with a part 5f for closing the opened part, used for closing a partial area of the opened part 5e in the upper end 5d, which then becomes a lower side when the cover part is rotated to open an opening part of the container body.SELECTED DRAWING: Figure 8
