The investigation of surface modification of Egyptian calcium carbonate via polymers was achieved with simultaneous ultra-fine grinding. Attrition mill and planetary mill were used for wet and dry grinding, respectively. The parameters affecting the grinding were studied such as ball number, speed and grinding time. The rheological characteristics of the aqueous calcium carbonate suspensions were studied in the presence of different types of polymers. The results indicated that the mechanical force could clearly affect the modification characteristics of calcium carbonate due to its mechanochemical effects. The viscosity of calcium carbonate suspension depends on the volume percentage or weight percentage. The dispersing agent increases the solid concentration for a given particle fineness.
