Abstract
When the cement grinding is performed in the ball mill, the grinding efficiency decreases due to
 the aggregation of the particles by the electrostatic phenomenon. Therefore, a lot of techniques
 for preventing agglomeration using various grinding aids have been introduced. In this study, for
 mineral grinding, the grinding aid composition including a water-soluble aluminate compound
 and the grinding method in which this grinding aid is used were described. Grinding aids based
 on aluminate-based compounds not only have high grinding efficiency but are also thermally
 stable as they are inorganic materials. Compared with the conventional grinding aids based on
 organic materials such as DEG and TIPA, even if the solid content is half contained, the grinding
 efficiency is similar and thus the cost can be reduced to half.
