In the cement industry production, in order to improve the grinding efficiency, reduce the power consumption of the mill, reduce the fineness of the cement, and improve the quality of the cement, a small amount of material-grinding aid must be added during the grinding process. The grinding aid is composed of one or more surface active substances and other chemical additives. It can reduce the surface energy of the grinding powder during the grinding process, overcome the attraction between the grinding powder, reduce the crushing resistance and prevent Paste the ball. Improve the fluidity of the mill, thereby reducing the power consumption of the mill and improving the grinding efficiency.
