Grinding process of calcium carbonat

By contrast, depending on the conditions of its production, precipitated calcium carbonate may contain some residual calcium hydroxide. because of the hardness of limestone, the grinding process is energy-intensive. anionic dispersants, including phosphates and acrylates, are used as grinding aids and to make the resulting slurry more stable in grinding mill.

Ground calcium carbonate is prepared by a process of grinding a suspension containing calcium carbonate and a water-soluble grinding agent in an aqueous medium while the temperature of the aqueous suspension is kept at or below 60 c.
