Abstract:
A method of continuously loading fibers in a fiber suspension with calcium carbonate, comprising the steps of:introducing a fiber suspension at a consistency of between approximately 10 and 45% and having at least one of calcium oxide and calcium hydroxide therein into a pulper; pulping the fiber suspension within said pulper; transporting the pulped fiber suspension from said pulper to an inner chamber of a fluffer; fluffing the pulped fiber suspension within said fluffer; transporting the fluffed fiber suspension into a reactor coupled directly with and positioned under said fluffer; injecting a reactant gas into at least one of said fluffer and said reactor, whereby each of said fluffer and said reactor are pressurized to a predetermined pressure; loading fibers within the fiber suspension with the chemical compound in said reactor; transporting the loaded fiber suspension to a mixing device; pulping the loaded fiber suspension within said mixing device; and discharging the pulped and loaded fiber suspension from said mixing device.
