Abstract

본 발명은 채광된 국내고령토광을 순수한 고령토와 사장석(칼슘장석)과 석영 등의 주립불순광물을 분리하는 것에 있어서, 채광된 고령토광을 건조, 해쇄하여 체분리하되, 150메쉬 이상의 조립산물은 자력선별로 정제하고 분쇄하여 300메쉬 이상~150메쉬 이하의 분체는 유리용 원료 및 사료용으로 사용하고 325메쉬 이하의 분체는 공업용 분체로 제조하여 고무용, 프라스틱 아스타일용 및 일반 스파스틱 충전재등으로 사용할 수 있는 제품을 제조하는 기술과, 원광을 해쇄한 산물중 150메쉬 이하의 미립산물은 자력선별후 미분쇄하여 평균입도 d90=6.2㎛, d50=2.0㎛의 미립분체로 제조하고 600~750℃에서 환원소성처리하여 분체의 물성을 향상시키므로서 페인트용 은폐율향상 충전재로 제조하도록 한 것에 그 특징이 있다.The present invention is to separate the mined domestic kaolin ore and pure impurities such as plagioclase (calcite feldspar) and quartz impurity, drying and crushing the mined kaolin ore, the granulated product is more than 150 mesh By refining and pulverizing, powders of 300 mesh or more and 150 mesh or less can be used as raw materials for glass and feed, and powders of 325 mesh or less can be manufactured as industrial powder and used for rubber, plastic atstyle and general spatastic fillers. The fine-grained products below 150 mesh among the technologies for manufacturing the product and the ore crushed products are finely pulverized after magnetic screening and manufactured into fine powders with an average particle size of d90 = 6.2㎛ and d50 = 2.0㎛ and reduced firing at 600 ~ 750 ℃. It is characterized by the fact that the treatment is made of a filler for improving the concealment rate of paint while improving the physical properties of the powder.
