摘要： The disclosure concerns a process for grinding wood on a grinding stone and the grinding stone which grinds the wood. The grinding stone has a central core, which may be comprised of concrete or steel. The core has a free inner space. A water supply line extends along the free inner space. Outlets from the water supply line are directed toward the periphery of the core at the grinding zone of the grinding layer. Around the core is a grinding layer for grinding the wood. The grinding layer is permeable so that water can be transmitted through it. The permeability may arise from the porosity of the material of the grinding layer itself or through the provision of bores or gaps in the grinding layer. The grinding layer may be comprised of a group of segments covering the core and the gaps may be defined between segments. The core may have bores for delivering the water to the inside of the grinding layer. The water may be heated and/or pressurized for improving grinding.

摘要翻译： 本公开涉及在磨石上研磨木材和研磨木材的研磨石的方法。 研磨石具有中心芯，其可以由混凝土或钢构成。 核心有一个自由的内在空间。 供水管线沿自由内部空间延伸。 来自供水管线的出口在研磨层的研磨区域处指向芯的周边。 核心周围是用于研磨木材的研磨层。 研磨层是可渗透的，使得水可以透过它。 渗透性可以由研磨层本身的材料的孔隙率或通过在研磨层中提供孔或间隙而产生。 研磨层可以由覆盖芯的一组部分组成，间隙可以在片段之间限定。 芯可以具有用于将水输送到研磨层内部的孔。 水可以被加热和/或加压以改善研磨。

摘要： A wood pulp grinder includes a grinder housing for supporting wood to be ground above a grindstone. A main press chamber in the grinder housing supports a main press ram which moves toward and away from the grindstone. When the main press ram is upraised, the main press chamber is charged with wood to be ground. Adjacent one or both circumferential sides of the main press chamber is disposed a respective auxiliary press ram with is movable toward the grindstone independently of the motion of the main press ram for retaining pressure upon the wood in the grinder housing while the main press ram is not pressing upon the wood. The auxiliary press ram or rams are relatively long in a lengthwise direction, having a length equal to fifty percent and preferably at least eighty percent of their active press stroke. The active lower surface of the auxiliary press ram may be inclined generally in a direction tangent to the surface of the grindstone or may be curved convexly toward the grindstone. When the main press ram is being retracted for reloading the press chamber, a closure plate moves across the bottom of the press chamber for preventing reverse movement of the wood.

摘要翻译： 木浆研磨机包括用于支撑被磨在磨石上方的木材的研磨机壳体。 研磨机壳体中的主压力室支撑朝向和远离磨石移动的主压力机冲头。 当主压力机升高时，主压力室装有待研磨的木材。 相邻的主压力室的一个或两个周向侧面设置有相应的辅助压力机压头，其可以独立于主压力机的运动而朝着磨石运动，以便在主压力机壳体上保持压力到研磨机壳体上的木材上 压在木头上。 辅助压力机柱塞或柱塞在长度方向上相对长，其长度等于其主动冲压冲程的百分之五十，优选至少百分之八十。 辅助压力机压头的活动下表面可以大致沿与磨石表面相切的方向倾斜，或者可以朝着磨石凸出弯曲。 当主压力机压缩机用于重新加载压力室时，封闭板移动通过压力室的底部，以防止木材的反向移动。

摘要： A flotation cell featuring a mixing pipe which enters the suspension essentially vertically, follows the point of air intake, and generally receives the entire suspension quantity per flotation cell, the injector of the flotation cell is offset sideways relative to the vertical center axis of the round container cross-section and away from the side on which the foam removal opening and the liquid drain opening are located. The mixing pipe (1) enters the suspension only for a distance such that its discharge opening, mouth (2), is located at least at one-half the height of the level of the overflow edge (7) of the foam removal channel (8), figured from the container bottom. The liquid drain opening (9) is preferably provided in the immediate vicinity of the container bottom, with a cover plate (11) extending across the length of the flotation cell and forming a drain channel (12) into which proceeds the clean liquid through an upper (14) and a lower (13) slot.

摘要： A sorter having a rotationally symmetric screen including a drain space for receiving overflow material (rejects) connected axially above the screen. A screen space is provided radially outside of the screen and an accepts drain space is connected to the screen space above the screen and surrounding the drain space. The screen space receives the flow through material (accepts) and, in its upper portion, includes a gas space for dampening.
