Abstract: A device for manufacturing finely powdered spherical magnesium includes a gas compressor that compresses argon gas, a gas heating unit that heats the compressed argon gas, and a tundish that receives molten magnesium. The device further includes a reactor having a nozzle injection unit that injects heated argon gas into the reactor, a recovery unit that recovers magnesium powder produced in the reactor, and a first gas cooler that cools the argon gas passing through the recovery unit. The device further includes a filtering unit that filters the cooled argon gas, a buffer tank that receives the filtered argon gas, and a compression blower that adiabatically compresses the argon gas. The device further includes a second gas cooler that cools the compressed argon gas, an adiabatic expansion duct that adiabatically expands the cooled argon gas, supplies the expanded argon gas to the reactor, and cools the magnesium powder.
