Manufacturing process of a simultaneously ground calcium carbonate material of the CCM and CCP type with a specific tilt factor

摘要

Manufacturing process of simultaneously ground calcium carbonate material comprising CCM and CCP, which has an inclination factor, defined as d30 / d70 x 100, of at least 30, preferably of at least 40, and more preferably of at least 45 , and is characterized in that it comprises the steps of: (a) providing CCM in the form of an aqueous suspension, (b) simultaneously grinding CCM and CCP, optionally with at least one other mineral material, until the inclination factor, defined as d30 / d70 x 100, be at least 30, preferably at least 40, and most preferably at least 45 (c) optionally, screen and / or concentrate the ground calcium carbonate material simultaneously obtained after step (b) , (d) optionally, drying the ground calcium carbonate material simultaneously obtained following step (b) or (c).
