INVESTIGATION ABOUT THE EFFECT OF CHEMICAL GRINDING AIDS ON CEMENT MILLING AND SEPARATION EFFICIENCY M. Magistri1, P. D'Arcangelo1, R. Albano1, D. Salvioni2 1Mapei S.p.A. Cement Additives Division, Milan, Italy 2Mapei S.p.A. Microscopy Lab, Milan, Italy ABSTRACT Cement manufacturing involves a grinding process of clinker, gypsum and secondary mineralCAC Grinding Aid is an excellent grinding aid for both, Ball mill and Vertical mill. In vertical mills, it leads to a stable bed thickness which reduces the vibration and stabilizes the mill operation for lower power consumption. It also avoids lump formation and improves flowability and reactivity.
