Abstract:
A method of producing particles by bringing plural dissimilar materials A and B into contact with each other includes feeding a liquid into a reactor from a first end portion of the reactor such that the liquid flows along the inner peripheral surface of the reactor and generating a vortex flow toward a second end portion in the reactor by the feed of the liquid; disposing a flow-assisting blade capable of rotating around the central axis line in the reactor and rotating the flow-assisting blade; and injecting materials to be contacted A and B into the reactor, discharging a contacted liquid from the second end portion of the reactor, and generating the particles in the contacted liquid.
Abstract:
To provide a processing device which is small but which can exhibits a sufficient processing amount and a uniform contact processing property. In the processing vessel 10, a liquid flow is set to a spiral flow, and in a contact processing field, the injection liquid A, B are injected at a center-side position with respect to an inner surface of the processing vessel so as to perform contact processing.
Abstract:
To obtain metal agglomerate having stable particle sizes and substantially spherical shapes, the method allows, by a circulation unit, a flow of a liquid containing metal to pass through a processing vessel and an external circulation path, and a part of the liquid from the processing vessel to be extracted to an outside in a substantially continuous manner so as to return to the processing vessel after it goes through the external circulation path, sets a flow velocity in the external circulation path to be 1 m/second or more, and injects at least a part of a liquid concentrate containing a reactant to be newly added into the external circulation path.

Abstract:
Liquid flow in a reaction processing vessel 10 is set to a spiral flow, a liquid A and B as an additional liquid containing an inorganic substance to be added is injected at a center-side position with respect to an inner surface of the reaction processing vessel 10 in a reaction field of the reaction processing vessel 10 so as to perform reaction processing.
