Beschreibung
Zusammenfassung:	The present invention relates to a grinding aid composition used in a process of grinding a cement clinker. According to the present invention, a grinding aid is a phosphorous-based compound. More particularly, an alkyl phosphate compound is used as a grinding aid. Particularly, a tributyl phosphate compound can be used as a grinding aid. According to the present invention, an alkyl phosphate compound only or a mixture of the alkyl phosphate compound can be used for the grinding aid composition. Also, an aqueous glycols and an ethylene amine-based compound can be added. The grinding aid of the present invention increases long term compression strength of cement, and reduces energy consumption while improving particle fineness by preventing coagulation of particles during a clinker grinding process. 본 발명은 시멘트 클링커의 분쇄공정에서 사용하는 분쇄조제 조성물이다. 본 발명에 따른 분쇄조제는 인계화합물로서, 보다 구체적으로 알킬포스페이트 화합물이 사용된다. 특히 트리부틸포스페이트 화합물을 사용할 수 있다. 본 발명에 따른 분쇄조제 조성물은 알킬포스페이트 화합물을 단독으로 또는 혼합하여 사용할 수 있으며, 수용성 글리콜류 및 에틸렌 아민계 화합물을 첨가하여 사용할 수 있다. 본 발명에 따른 분쇄조제는 시멘트의 장기 압축강도를 향상시키며, 클링커 분쇄공정에서 입자들 사이의 응집을 방지하여 에너지 소모량을 줄이고 분말도를 향상시킬 수 있다.
