Refining member for pulp refiner with refiner bars and teeth
A recently granted patent (Publication Number: US11905658B2) discloses a refining member for a pulp refiner that includes a disc-shaped refining body with refiner bars and teeth on a planar refining surface. The refiner bars refine wood fibers, while the teeth break up fiber bundles. The refiner bars have specific dimensions, with a height ranging from about 4 mm to 10 mm and a width between 2 mm to 8 mm. Additionally, the refining member features dams in some refiner grooves and a continuous floor in each refiner groove and bar, ensuring efficient refining and separation of wood fibers.
Furthermore, the patent describes a pulp refiner comprising a frame and refining members with coaxial planar refining surfaces that define a refining space. A rotor facilitates relative movement between the refining members, refining wood pulp slurry and separating fiber bundles. The teeth on the refining members are arranged in annular rows, with intermeshing teeth enhancing the refining process. The patent also details the configuration of non-rotating stator and rotating rotor members, ensuring optimal refining efficiency. Each refiner bar and groove extends continuously on the planar refining surface, with the teeth projecting to a greater height than the refiner bars, emphasizing their role in breaking up fiber bundles for improved pulp refining.
