Provided is a wet atomizer for processing all-solid-state battery raw materials while ensuring sealing property, operability after completion of processing, and maintenance property. The wet atomizer includes a liquid supply pump for supplying the all-solid-state battery raw materials, a pressure intensifier for pressurizing the all-solid-state battery raw materials supplied from the liquid supply pump, a high-pressure filter for filtering the all-solid-state battery raw materials pressurized by the pressure intensifier, a chamber for injecting the all-solid-state battery raw materials filtered by the high-pressure filter, a sealing member for sealing the space for processing the all-solid-state battery raw materials, and an inert gas supply unit for supplying an inert gas to the sealing member.

The mixing state of static mixing is optimized, so that it is possible to form silver halide emulsion particles in small sizes with an excellent mono-dispersion characteristic. An aqueous solution of haloid salt is blown out from a first nozzle into a mixing chamber as a rectilinear flow of turbulent flow, and before eddy viscosity formed when the rectilinear flow is blown out from the first nozzle of a small diameter to the mixing chamber of a greater diameter reaches a maximum, or before a maximum flow speed of the rectilinear flow is reduced to {fraction (1/10)} or below, an aqueous solution of silver nitrate is blown out from a second nozzle as a crossflow of turbulent flow which crosses the rectilinear flow at a substantially right angle and is entrained by the rectilinear flow, so that the two solutions are allowed to mix and react with each other instantaneously, and a liquid resulting from the mixing and reaction is discharged from a discharge duct.
