Abstract (en)
[origin: WO03066962A1] The invention relates to a method for preparing fibres contained in a pulp suspension, comprising the following steps: provision of the fibres in the form of a suspension with a predeterminable solid concentration; loading of the fibres with a precipitation product; grinding of the fibres loaded with the precipitation product to produce precipitation product particles with maximum dimensions ranging between approximately 0.05 and 5 mu m. The invention is characterised in that crystalline precipitation product particles are produced and said production of the latter takes place in an online process directly in the stock preparation line.
