GRINDING AID FOR FINELY GRINDING MINERALS AND GRINDING METHOD USING SAME
The present invention relates to a grinding aid for finely grinding minerals and a grinding method using the same, the grinding aid comprising: a compound having a polyvalent hydroxyl group selected from glycerin or glycol; and a polyvalent hydroxyl group-containing aromatic compound generated by a reaction of an aromatic acid. The grinding aid of the present invention reduces residue and controls fineness, thereby improving grinding efficiency when used in a fine grinding process of minerals such as a cement material.
La présente invention concerne un adjuvant de broyage pour le broyage fin de minéraux et un procédé de broyage l'employant, l'adjuvant de broyage comprenant : un composé comprenant un groupe hydroxyle polyvalent choisi parmi la glycérine ou le glycol ; et un composé aromatique contenant un groupe hydroxyle polyvalent produit par réaction d'un acide aromatique. L'adjuvant de broyage de la présente invention réduit les résidus et régule la finesse, ce qui permet d'améliorer l'efficacité de broyage lorsqu'il est utilisé dans un procédé de broyage fin de minéraux tels qu'un matériau de ciment.
본 발명은 글리세린류 또는 글리콜류 중에서 선택된 다가 하이드록시기를 가진 화합물과 방향족 산의 반응으로 생성된 다가 하이드록시기-함유 방향족 화합물을 포함하는 광물의 미분쇄용 분쇄조제 및 이를 이용한 분쇄방법에 관한 것으로, 본 발명의 분쇄조제는 시멘트원료와 같은 광물의 미분쇄공정에 사용하였을 때 잔사를 줄이고 분말도를 조절하여 분쇄효율이 향상된다.
