Abstract
In a process for the preparation of aqueous suspensions of fillers and/or pigments having defined particle size distributions, an aqueous initial suspension of fillers and/or pigments is prepared and is subjected to gravity screening (gravity separation) and, after at least a predetermined duration of the gravity screening, at least one separated suspension of fillers and/or pigments having an appropriate particle size distribution is withdrawn. The preparation of these aqueous suspensions is carried out using, in particular, a through-flow centrifuge. Also disclosed are certain pigment suspensions for the paper industry. The new pigments and suspensions of fillers and/or pigments can be used in particular in the production of paper, in the size press of the paper-making machine, for coating paper and cardboard, in the paper precoating and as the top coating of paper and cardboard. <IMAGE>
