SPHERICAL POWDER MANUFACTURING APPARATUS AND PRODUCTION METHOD FOR SPHERICAL POWDER

摘要

PROBLEM TO BE SOLVED: To provide a spherical powder manufacturing apparatus capable of obtaining stable spheroidal quality at a low cost and a production method for spherical powder. SOLUTION: A spherical powder manufacturing apparatus 10 comprises a burner 30 for forming combustion flame F in a chamber 20, and granules are charged into the flame F as material powder 100a to obtain the processed spherical powder 100c. A gas current generating section 60 is provided in the upper part of the chamber 20 to form an air-curtain-like gas current A falling from the upper part to the lower part of the chamber 20.
