distribution, thus obtaining a finer and better performing cement. Grinding aids act at two levels: in the mill, with the reduction of cement coating on grinding media and mill lining, and in the separator, with the improvement of classifiion process. Detailed description of the use of grinding aids in cement industry is reported elsewhere .
the industrial grinding of cement, even without the use of grinding aids. Therefore it can be assumed that the surfaces of the majority of commercial clinkers are predominantly or even completely hy droxylated. This is also important because it assists the grinding, in other words water is a weak grinding aid. The chemical reaction of oxide ions
Cement grinding aid characteristics. A grinding aid is a surfactant that can improve the grinding environment. The common grinding aid is to improve the grinding effect by improving the viscosity of the material in the mill, the dispersion of the particles and the flow state of the slurry.
