A powder processing apparatus includes a main body portion having a cylindrical rotor rotating at a high speed, and a cylindrical stator arranged coaxially with the rotor, outside the rotor with a gap therebetween; a supply port provided at one end of the main body portion, and supplying a processing raw material into the gap together with an airflow; and a discharge port provided at the other end of the main body portion, and discharging, from the gap, a processed product obtained by spheroidizing the processing raw material between the rotor and the stator. In the inner peripheral surface of the stator, there are provided circumferential grooves orthogonally intersecting the axis line of the stator, or a spiral groove forming an angle of not less than 60 degrees and less than 90 degrees with respect to the axis line.
