Abstract

본 발명은 통상 제철소에서 발생되는 석회석 슬러지를 괴상화 처리한 다음 건조 및 적절한 소성하므로서 석회석 슬러지를 재활용함은 물론 분발생이 없는 생석회 분말을 제조하는 방법을 제공하고자 하는데, 그 목적이 있다.The present invention is intended to provide a method for producing lime powder sludge as well as recycling limestone sludge by massifying the limestone sludge generated in steel mills and then drying and appropriate firing, the object is to.

상기 목적을 달성하기 위한 본 발명은 생석회 제조과정에서 발생되는 석회석 슬러지를 통상의 방법으로 괴상화 처리한 후 건조시킨 다음, 850-1050℃의 온도에서 40-80분 동안 소성하는 석회석 슬러지를 이용한 분생석회의 제조항법에 관한 것을 피 요지로 한다.In order to achieve the above object, the present invention uses a limestone sludge produced by coagulating limestone sludge produced in quicklime manufacturing process in a conventional manner and then drying, and then calcining at a temperature of 850-1050 ° C. for 40-80 minutes. A summary of the navigation for the manufacture of quicklime.
