Abstract
본 발명은 괴상의 시멘트 클링커와 첨가제, 예를 들면 슬래그 및/또는 석고의 혼합물을 분쇄하여 최종생성물인 시멘트를 제조하는 방법 및 장치를 제공하기 위한 것으로, 본 발명에 따른 방법 및 장치는 상기의 혼합분을 롤러프레스에서 1차 분쇄하고, 이 분쇄물을 공기식 해쇄분급기에서 미립분과 조립분으로 동시에 해쇄 및 1차 분급시킨 후 사이클론에서 포집된 미립분과 2차 분쇄기인 롤 밑에서의 조립분으로부터 분급기에서 최종 생성물을 2차 분급하고, 분급된 조립분은 상기 공기식 해쇄분쇄기에서의 일부 조립분과 함께 볼 밑에서 2차 분쇄하고, 이 분쇄물을 상기 2차 분급기로 순환시키게 된다.The present invention is to provide a method and apparatus for producing a final product cement by grinding a mixture of bulk cement clinker and additives, for example slag and / or gypsum, wherein the method and apparatus according to the present invention are a mixture of The powder is first pulverized in a roller press, and the pulverized powder is pulverized and firstly sorted into fine powder and granulated powder simultaneously in an air pulverizer, and then separated from the granulated powder collected in a cyclone and granulated powder under a roll which is a secondary pulverizer. In the air supply, the final product is classified secondly, and the sorted granulated powder is secondaryly crushed under the ball together with some of the granulated powder in the pneumatic pulverizer, and the pulverized product is circulated to the secondary classifier.
본 발명 시스템에 의한 해쇄, 분급 및 분쇄과정을 거친 최종 생성물은 시멘트 분말은 롤러 프레스 분쇄 생성물의 지나치게 경사진 입도분포특성을 개성하고, 종래의 공지된 분쇄 시스템에 비해 마모문제를 감소시킬 뿐 아니라 롤러 프레스 압착물질중 미립분의 불필요한 2차 분쇄과정을 배제함으로써 입도조정이 가능하고, 분쇄에너지가 종래의 공지된 시스템에 비해 7 내지 15% 증가되는 효과를 얻을 수 있다.The final product, which has been pulverized, classified and pulverized by the system of the present invention, has a cement powder that exhibits excessively inclined particle size distribution characteristics of the roller press pulverized product. The particle size can be adjusted by excluding unnecessary secondary grinding of the fine powder in the press compacted material, and the effect of increasing the grinding energy by 7 to 15% compared to a conventionally known system can be obtained.
