    • A refiner has a frusto-conically shaped grinding zone located between an outer housing and an inner frusto-conical rotor. The rotor has suitable openings for removing steam from the grinding zone inwardly into an interior chamber within the rotor. Multiple separation stages are provided in the rotor and between it and the housing, respectively, whereby separation of the steam and any following fibrous material particles is effected. By removing the steam from the grinding zone, increased retention time of the fibrous material in the grinding zone and increased production is effected.
    • 精磨机具有位于外壳体和内截头圆锥形转子之间的截头圆锥形磨削区域。 转子具有合适的开口,用于将研磨区的蒸汽向内移入转子内的内部室。 分别在转子及其与壳体之间设置多个分离台,从而实现蒸汽和任何后续的纤维材料颗粒的分离。 通过从研​​磨区除去蒸汽,可以提高纤维材料在研磨区中的保留时间,并增加生产。

    • A pulp containing lignocellulosic fibers is treated with chlorine in two steps. In the first step, chlorine in the amount of 0.6-0.9 grams per gram of lignin in the fibers, is mixed in the gaseous state into the pulp and in a second step the reaction products, which contain chlorinated lignin, are removed by displacing the liquid in the pulp with a chlorine solution, the amount of active chlorine in the solution in the second step being between 0.1 and 0.3 grams per gram of the lignin initially present in the pulp. In this manner 92% delignification is achieved without any intermediate washing between the two steps and with a total amount of chlorine between 0.7 and 1.2 grams per gram of lignin. The consistency of the pulp in both steps is the same and is between 6 and 12%.
    • 含有木质纤维素纤维的纸浆分两步处理氯气。 在第一步中,纤维中每克木质素0.6-0.9克的氯以气态混合到纸浆中,在第二步中,含有氯化木质素的反应产物通过置换 用氯溶液在纸浆中的液体,第二步溶液中活性氯的量为0.1至0.3克/克初始存在于纸浆中的木质素。 以这种方式,在两步之间没有任何中间洗涤并且氯的总量在每克木质素0.7至1.2克之间达到92%的脱木质素。 纸浆在两个步骤中的一致性相同,为6%至12%。
