The materials to be processed are powders that are easily melted by the heat of friction with the grinding mill. The grinding mill comprises a casing (2) that is provided with a cylindrical inner surface, a rotor (10) that rotates around the shaft center (X) of the casing (2) and on the outer surface of which a rough area (10G) is formed, an airstream-forming means (26) that forms an airstream for transporting the powder from a supply port (3) provided at one end of the casing (2) in the direction of the shaft center (X) towards a discharge port (4) provided at the other end, a coolant supply means (P) that flushes coolant through a coolant channel (15) formed inside the rotor (10), and a coolant circuit (23). The rough area (10G) is partitioned in the direction of the shaft center (X) by a circular cutout portion (11) that extends along the circumference of the rotor (10).
