Abstract
An apparatus for loading fibers in a fiber suspension with calcium carbonate has a housing with an inlet and an accept outlet. A rotatable distribution member is positioned within the housing. A rotor and stator assembly is positioned within the housing radially outside of the distribution member. A toothed ring is interposed between the distribution rotor and the rotor and stator assembly. The toothed ring and the rotor and stator assembly define a gas ring therebetween. A reactant gas supply is fluidly coupled with the gas ring.
Claims21
An apparatus for loading fibers in a fiber suspension with calcium carbonate, comprising:
- a housing having an inlet and an accept outlet;
- a rotatable distribution member positioned within said housing;
- a rotor and stator assembly positioned within said housing radially outside of said distribution member, including a rotor and stator in opposed relationship defining a gap therebetween, said gap being between approximately 0.5 mm and 100 mm;
- a toothed ring interposed between said distribution member and said rotor and stator assembly, said toothed ring and said rotor and stator assembly defining a gas ring therebetween;
- and
- a reactant gas supply fluidly coupled with said gas ring.
An apparatus for loading fibers in a fiber suspension with calcium carbonate, comprising:
- a housing having an inlet and an accept outlet;
- a rotatable distribution cross within said housing, said distribution cross including a plurality of radially extending paddles, said distribution cross having an axis of rotation;
- a rotor and stator assembly positioned within said housing radially outside of said distribution cross, including a rotor and stator in opposed relationship defining a gap therebetween, said gap being between approximately 0.5 mm and 100 mm;
- a toothed ring interposed between said distribution rotor and said rotor and stator assembly, said toothed ring having a plurality of teeth extending generally parallel to said axis of rotation and spaced apart from each other, said toothed ring and said rotor and stator assembly defining a gas ring therebetween;
- and
- a reactant gas supply fluidly coupled with said gas ring.
