摘要： Method and apparatus for controlling the refining of fibrous lignocellulose pulp material in which the pulp stock or grist is conveyed into a cylindrical stationary drum (10) and propelled therein in a linear direction in a pulsating fashion by a co-axial rotor (14) comprising a plurality of impellers (21) which attack the grist in a wedging action as it is compacted by the centrifugal force of rotation and pushed ahead of the leading edges of the impellers (21) and thus inducing in the grist internal frictional shear forces while it is forced through a gap defined between the terminal edges of the impellers (21) and a series of shear members (12) arranged axially along the interior surface (11) of the drum (10). The shear members (12) are detachably and adjustably anchored in slots in the peripheral wall of the drum (10) to vary the gap clearance. A plurality of adjustable plow members (34) for enhancing the linear flow of the grist through the drum (10) may be additionally mounted in the peripheral wall of the drum (10) to extend radially inwards to engage accommodating slots (35) in the impellers (21) to thereby regulate the amount of grist pushed ahead during each revolution of the impellers (21) and to control the centrifugal force exerted on the grist.

摘要： Method and apparatus for controlling the refining of fibrous lignocellulosic pulp in a drum refiner in which the pulp stock, or grist, is conveyed into a cylindrical stationary drum (10) and propelled therein in a linear direction in a pulsating fashion by a co-axial rotor (18) comprising a plurality of wings (23) which attack the grist in a wedging action as it is pushed ahead of the leading faces of the wings and which induce in the grist internal frictional shear forces while it is forced through a gap defined between the leading edges of the wings (23) and a series of shear means (28) arranged axially along the interior surface of the stationary drum (10). The process is controlled by coordinating the angle of attack on the grist by the wings (23) and corresponding variations in the gap clearance with the energy demands or mechanical power input.
摘要翻译：用于控制在磨浆机中的纤维状木质纤维素浆料的精炼的方法和装置，其中纸浆原料或粗粒料被输送到圆柱形固定鼓（10）中并在其中沿着线性方向以脉动方式通过同轴方向转子（18）包括多个机翼（23），当翼被推到机翼的前表面之前，该楔形件以楔形动作攻击格栅，并且在被迫通过间隙限定的内部摩擦剪切力在所述翼部（23）的前缘和沿着所述固定滚筒（10）的内表面轴向设置的一系列剪切装置（28）之间。该过程是通过机翼（23）的协调角度对间隙的间隙和能量需求或机械功率输入的间隙间隙的相应变化来控制的。
