The invention discloses a centrifugal atomization production device for passivated metal lithium microspheres. The centrifugal atomization production device comprises a lithium melting tank and a passivating tank. The lithium melting tank is provided with a heater. The bottom of the lithium melting tank is connected with the top of the passivating tank through a conveying pipeline. An outlet part of the conveying pipeline stretches into the passivating tank. A centrifugal atomizer connected with an outlet of the conveying pipeline is fixed to the top of the passivating tank. The passivating tank is provided with an air flow cooling circulation system. A discharging outlet is formed in the bottom of the passivating tank and in sealed connection with a feeding inlet of an argon glove box. A screening device and a collection box which are mutually connected are arranged in the argon glove box. The collection box is arranged below the screening device. The screening device is connected with the discharging outlet of the passivating tank. A transition cabin door is arranged on the argon glove box. No solvent needs to be used, and the surfaces of the prepared metal lithium microspheres are clean.
