    • 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.
    • 纤维浆料精磨机包括壳体,固定到转子轴的转子以及第一和第二多个研磨表面。 转子设置在壳体内并可经由转子轴旋转。 所述第一多个研磨面固定在所述转子上,所述第二多个研磨面被配置为面对所述第一多个研磨面并固定在所述壳体内。 用于多个研磨表面中的每一个的入口板将纤维浆料引导朝向一组相对的第一和第二研磨表面,并且向纤维浆料赋予旋转流。
