Abstract (en)
[origin: WO2005056918A1] The invention relates to a method for charging a fibre suspension, containing cellulose fibres, with calcium carbonate. Said method comprises the following steps: Calcium oxide or calcium hydroxide is introduced into the fibre suspension in a liquid or dried form; gaseous carbon dioxide is introduced into the fibre suspension and calcium carbonate in ball-shaped agglomerations (49) of crystals is precipitated by the carbon dioxide. The invention also relates to an arrangement for charging the fibre suspension containing cellulose fibres.
