MANUFACTURING APPARATUS OF HIGH PURITY SPHERICAL ALUMINA AND THE MANUFACTURING METHOD OF HIGH PURITY SPHERICAL ALUMINA USING THIS

摘要

The present invention relates to a manufacturing apparatus for high purity spherical alumina through which high purity spherical alumina having high particle sizes can be obtained; and to a manufacturing method of high purity spherical alumina using the same. The manufacturing apparatus of the present invention comprises: a first unit which mixes injected raw materials in powder form with washing water and stirs the mixture for a fixed amount of time; a second unit which removes volatile ions blended in the raw materials from the raw materials discharged from the first unit in slurry form; a spheroidizing furnace which injects the raw materials discharged from the second unit into flame of the furnace and spheroidizes the raw materials; and a third unit which is arranged on one side of the spheroidizing furnace and maintains the temperature of the flame to be in a range above or below certain temperature while removing impurities included in the injected raw materials discharged from the second unit with respect to melting points.
