Abstract: Method and device for producing ball-shaped metallic particles substantially equal in diameter are disclosed. The device comprises a cylindrical metallic housing and a vessel provided on the cylindrical metallic housing. The vessel has a plurality of small openings through a bottom plate thereof. A vibrator is disposed above the vessel in a manner that the vessel may be subjected to vibration. A pair of pipes are provided to deliver and fill nitrogen or inert gas within the housing. An inclined bottom plate having a soft layer is arranged at a bottom portion of the housing to form a shielding structure. An exhaust pipe is provided at an outlet of the inclined bottom plate, and a selector is arranged at a bottom outlet of the shielding structure.
