Abstract
An apparatus for preparing an inorganic spheroidized particle, wherein an inorganic powder is fed from a feed pathway for an inorganic powder to a combustion flame in a powder melting furnace, and melted or softened and spheroidized, and wherein the apparatus comprises a powder dispersing plate in the feed pathway for an inorganic powder; and a process for preparing an inorganic spheroidized particle comprising the step of preparing inorganic spheroidized particles with the apparatus for preparing inorganic spheroidized particles as defined above. The inorganic spheroidized particle prepared by the above process and apparatus can be suitably used for a spherical molding sand, a filler, a pigment or the like, especially in the case where the inorganic spheroidized particle is a ceramics particle.
