The invention discloses a pneumatic filling system for powder particles. The pneumatic filling system comprises a storage box, a gas cylinder and a powder box; the storage box is a cylindrical body; the front end of the storage box is in the shape of a cone; a piston is coaxially sleeved with the storage box; the inside of the storage box is divided in the axial direction from front to back into afluidization cavity and a driving cavity which are arranged independently; a powder outlet is formed in the front end of the fluidization cavity and is in pipeline connection with the powder box; thecone at the front end of the fluidization cavity and the back end of the driving cavity are in pipeline connection with the gas cylinder; the driving cavity and the fluidization cavity are filled with gas inside the gas cylinder; the gas entering the driving cavity drives the piston to push the powder particles inside the fluidization cavity to move forwards, and meanwhile, the powder particles is fluidized in the gas by
