The object of the invention is to provide a powder granulation method that affords greater operation efficiency and working efficiency and enhanced product recovery rate by preventing powder from being adhered to a container inner wall while suppressing variability in particle size of product to the utmost. To attain this object, a plurality of scrapers 13, 14, and 15 are disposed so as to abut or come close to the inner face of a bottomed cylindrical container 11 that accommodates powder so that the powder in the container is granulated by causing an inner bottom surface 11a of the container 11 to rotate on a horizontal plane. |
