The purpose of the present invention is to supply powders of various types, in a consistent manner. This powder supply apparatus (100) is provided with: a plurality of drive rollers (11), the axes of which are arranged on the horizontal; a cylindrical rotating hopper (20) driven to rotate about the axial center thereof as the center of rotation; a linking port (21) for charging powder into the rotating hopper (20); a chuck part (30) supporting the rotating hopper (20) air-tightly and in rotatable fashion; a powder discharge passage (40) connecting the inside and outside of the rotating hopper (20) through the chuck part (30); a scooping part (50) for continuously scooping up the powder by means of rotation of the rotating hopper (20); and a pressurization passage (60) for pressurized air to pressurize the rotating hopper (20) interior. In this powder supply apparatus (100), the inner terminus (41) of the powder discharge passage (40) opens at the location at which the scooped up powder drops from the scooping part (50). |
