| titleOfInvention | Process to improve the particle size distribution of a material containing calcium carbonate |
| abstract | Process for the preparation of an aqueous suspension comprising at least one material containing calcium carbonate, said process comprising: a) providing a substantially dispersant-free aqueous suspension of at least one material containing calcium carbonate, wherein the dispersion comprises dispersants in an amount <0.05% by weight based on the total dry weight of said at least one material containing calcium carbonate, b) preheating the suspension from step a) to a temperature of 40 to 95 ° C at ambient pressure, c) contacting the aqueous suspension of step a) before and / or during and / or after the pre-heating step b) and / or before and / or during and / or after the step wet milling d) with at least one base, to obtain an aqueous suspension having a pH measured at 25 ° C> = 9.0, and d) wet grinding the previously heated suspension from stage b) or from stage stage c) in at least one milling stage a to obtain an aqueous suspension of at least one calcium carbonate-containing material having a ratio between the particles having a d80 value of the mean particle size and the particles having a d20 value of the mean particle size [d80 / d20] <= 2.50. |
