Abstract
Process for grinding calcium carbonate in an aqueous medium in the presence of a water-soluble grinding agent in a quantity which is much smaller than that used in the prior art, which is characterised in that the grinding medium comprises grinding bodies, the aqueous phase containing the grinding agent and the calcium carbonate to be ground in suspension is maintained during the grinding operation at a temperature of less than 60 DEG C. The suspension produced by the grinding and the ground calcium carbonate collected after removal of the aqueous phase can be applied in the fields of mass filling and paper coating and of fillers for paint and plastics.
