INORGANIC SPHEROIDIZED PARTICLE MANUFACTURING APPARATUS AND INORGANIC SPHEROIDIZED PARTICLE MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an inorganic spheroidized particle manufacturing method that can produce an inorganic spheroidized particle having reduced ionic impurities by a simple method without performing a water washing step and a drying step and to provide an inorganic spheroidized particle manufacturing method.;SOLUTION: The inorganic spheroidized particle manufacturing apparatus is an apparatus for manufacturing an inorganic spheroidized particle by supplying an inorganic raw material powder into a flame 26 formed of a fuel and a combustion-supporting gas and melting/spheroidizing the inorganic raw material powder. The apparatus comprises: a spheroidizing furnace 28; a burner 25 disposed at a top of the spheroidizing furnace 28 for forming the flame 26 at a tip part 25A thereof; a bag filter 33 disposed at a subsequent stage of the spheroidizing furnace 28 for collecting an inorganic spheroidized particle supplied through a piping 31 from the spheroidizing furnace 28; and a vacuum pump 45 disposed at a subsequent stage of the bag filter 33 and connected to the bag filter 33.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
