Abstract
L'invention concerne un procédé permettant de réduire les coûts de fabrication et d'utilisation d'une charge, plus spécifiquement d'une charge à base de carbonate de calcium utilisée dans la fabrication du papier et du carton. Cette charge à base de carbonate de calcium est préparée par précipitation de particules de carbonate de calcium sur la surface de fibrilles de blousse. L'invention concerne également un procédé permettant de fabriquer et/ou de produire cette charge sous une forme pouvant être utilisée directement dans des applications de produits de papier ou de carton. En outre, l'invention concerne un procédé de fabrication de papier et/ou de carton, lequel procédé met en oeuvre la pâte chimique dans laquelle la charge est incorporée, cette pâte chimique étant séchée sous forme de balles de pâte chimique.
