Process for the manufacture of a material comprising calcium carbonate, the process comprising the steps of a) providing at least two aqueous suspensions comprising a material comprising calcium carbonate, where i) the first aqueous suspension has a solids content of 1.0 to 82.0% by weight, based on the total weight of the aqueous suspension, and a content of particles having a particle size <2 μm within the range of 1.0 to 30.0 % in weigh; and ii) the second aqueous suspension has a solids content of 10.0 to 82.0% by weight, based on the total weight of the aqueous suspension, and a content of particles having a particle size <2 μm within the range of 30.0 to 100.0% by weight; b) mixing the at least two aqueous suspensions provided in step a) to obtain an aqueous suspension mixture; c) crush the aqueous suspension mixture obtained in the mixing step b). |
