There is provided an apparatus for producing a spherical powder, comprising a cylindrical chamber having an axis extending in the vertical direction and a burner 30 provided in the upper part of the chamber to generate a combustion flame in the chamber, characterized in that the aggregate-crushing gas G is injected from the periphery part of the first supply pipe 61, which constitutes a raw material powder supply route O, into the first supply pipe 61. This configuration can allow a raw material powder to be supplied to the combustion flame with an aggregate of the raw material powder crushed, and suppress generation of coarse particles or unmelted particles resulting from aggregation of particles. The raw material powder to be supplied to the apparatus for producing a spherical powder may have a treating agent such as stearic acid, or a coupling agent added thereto for preventing aggregation. |
