    • An apparatus for screening a fibrous suspension including: a housing, conduits therein at least for fiber suspension being fed, reject and accept, and a rotor and a cylindrical screen drum installed in the housing, at least one of which is rotatable, whereby a surface of the rotor is provided with rotor elements in proximity to the surface of the screen drum, whereby each rotor element includes a front surface facing a flow of the fiber suspension, an upper surface and a trailing surface sloping from the upper surface towards the surface of the rotor, wherein the trailing surface of the rotor element is curved and sidewalls of the trailing surface converge at a back point of the rotor element.
    • 一种用于筛选纤维悬浮液的装置,包括:壳体,其中至少供给纤维悬浮液的导管,排出和接受,以及安装在壳体中的转子和圆柱形筛筒,其中至少一个可旋转, 在转子的表面附近设置有转子元件,由此每个转子元件包括面向纤维悬浮液的流动的前表面,从上表面向表面倾斜的上表面和后表面 转子,其中转子元件的后表面是弯曲的,并且后表面的侧壁会聚在转子元件的后端。
