Preparation device of metal lithium ball powder

A preparation device of metal lithium ball powder is characterized in that the preparation device comprises a smelting furnace, a heater and a screw extruder, the screw extruder extrudes fluid sent by the heater, and then the fluid is connected into the liquid input end of a gas-liquid mixer through a first mixing pipe; the gas input end of the gas-liquid mixer is communicated with a pressurizing pipe through a second mixing pipe, and the pressurizing pipe is communicated with an exhaust port of the booster pump, so that pressurized gas in the booster pump is input into the second mixing pipe; an output port of the gas-liquid mixer is communicated with an inlet of the atomizer, pressurized gas and liquid lithium are uniformly mixed through the gas-liquid mixer and then input into the atomizer, and the atomizer sprays out and atomizes the mixed fluid, so that countless atomized small particles are formed; the atomizer is mounted in the reaction chamber, the reaction chamber is arranged in the reaction tank, an
