Title (DE) VERFAHREN UND VORRICHTUNG ZUM BELADEN VON IN EINER FASERSTOFFSUSPENSION ENTHALTENEN FASERN MIT FÜLLSTOFF
(EN) METHOD AND DEVICE FOR LOADING FIBRES IN A FIBRE SUSPENSION WITH FILLER
(FR) PROCEDE ET DISPOSITIF D'INTRODUCTION D'UNE CHARGE DANS DES FIBRES CONTENUES DANS UNE SUSPENSION DE MATIERE FIBREUSE
Abstract:
(DE) Ein Verfahren zum Beladen einer Faserstoffsuspension von Zellulosefasern mit einem Füllstoff, insbesondere mit Calciumcarbonat, wobei Calciumhydroxid in flüssiger oder trockener Form in die Faserstoffsuspension eingebracht wird, ist dadurch gekennzeichnet, dass der Gehalt an Füllstoff, insbesondere in einer Bütte (2), einer Ableerbütte, einer Maschinenbütte oder dgl., und/oder in einer Rohrleitung durch eine Mischeinrichtung (4), insbesondere eine Rezirkulations- und/oder einer Bypasseinrichtung, geregelt wird.
(EN) The invention relates to a method for loading cellulose fibres in a fibre suspension with a filler, in particular, calcium carbonate. Calcium hydroxide in liquid or dry form is added to the fibre suspension, characterized in that the concentration of filler is controlled in a vat (2), a dump chest, a machine chest or similar and/or in a pipeline through a mixing device (4), in particular a recirculation and/or bypass device.
(FR) Procédé d'introduction d'une charge, en particulier de carbonate de calcium, dans une suspension de fibres de cellulose, de l'hydroxyde de calcium étant introduit sous forme liquide ou sèche dans la suspension de matière fibreuse. Ledit procédé est caractérisé en ce que la quantité de charge est régulée, en particulier dans une cuve (2), une cuve de décharge, un cuvier de machine ou analogue, et / ou dans une conduite, par un dispositif de mélange (4), en particulier un dispositif de recirculation et / ou de dérivation.
