Abstract
A fibrous slurry refiner includes a casing, a rotor secured to a rotor shaft, and first and second pluralities of grinding surfaces. The rotor is disposed within the casing and is rotatable via the rotor shaft. The first plurality of grinding surfaces is secured to the rotor, and the second plurality of grinding surfaces is disposed facing the first plurality of grinding surfaces and fixed in the casing. An inlet plate for each of the plurality of grinding surfaces directs the fibrous slurry toward a set of facing first and second grinding surfaces and imparts a rotary flow to the fibrous slurry.
