发明名称 Method of loading a fiber suspension with calcium carbonate
摘要 A method of loading fibers in a fiber suspension with calcium carbonate includes the step of transporting a fiber suspension to an inlet of a housing. The fiber suspension includes calcium oxide and/or calcium hydroxide. The fiber suspension is distributed from the inlet using a rotatable distribution member. The fiber suspension is passed through a toothed ring interposed between the distribution member and a rotor and stator assembly. A reactant gas is supplied to a gas ring defined between a toothed ring and the rotor and stator assembly. Calcium carbonate crystals are formed in the fiber suspension as the fiber suspension passes through the gas ring. The calcium carbonate crystals are distributed in the fiber suspension using the rotor and stator assembly.
