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.

Device for producing particles and method for producing particles

Liquid flow in a reaction processing vesselis 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 vesselin a reaction field of the reaction processing vesselso as to perform reaction processing.

Method of manufacturing reaction agglomerated particles, method of manufacturing cathode active material for lithium ion battery, method of manufacturing lithium ion battery, lithium ion battery, and device of manufacturing reaction agglomerated particles

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, 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.
