GRINDING DEVICE

The invention relates to a device for treating fibrous material， said device having two grinding gaps (2， 3) which are arranged in a housing (1) and through which fibrous material radially flows， said gaps each being formed by a treatment tool (5) rotating about an axis of rotation (8) and a non-rotating treatment tool (4)， wherein the treatment tools (4， 5) are each fastened to a base plate (6， 7)， have a rotationally symmetrical shape and are arranged coaxially with respect to one another， the two rotating treatment tools (5) are fastened to a common base plate (7) driven by a rotatably mounted shaft (9) and are arranged between the two non-rotating treatment tools (4)， the rotating base plate (7) is axially displaceably fastened to the shaft (9)， and the width of the grinding gaps (2， 3) can be varied by means of an axial displacement of at least one non-rotating base plate (6). The aim is to make a safe operation of the device possible by associating a measuring unit (10) for detecting the axial force (F) acting on the shaft (9) with the shaft (9).

本发明涉及一种纤维材料处理装置（device for treating fibrous material），该装置具有两个设置于壳体（housing）(1)内的研磨间隙（grinding gap）(2、3)，纤维材料径向流经该间隙。每个间隙均由绕旋转轴（axis of rotation）(8)转动的处理刀具（treatment tool）(5)与静止处理刀具(4)构成，其中，两类处理刀具(4、5)分别固定于基板（base plate）(6、7)，二者均呈旋转对称形状且彼此同轴布置。两个转动式处理刀具(5)固定于由可旋转安装的轴（rotatably mounted shaft）(9)驱动的共用基板(7)，并设置于两个静止处理刀具(4)之间。转动式基板(7)轴向可移动地固定于轴(9)，且通过至少一块静止基板(6)的轴向位移，可调节研磨间隙(2、3)的宽度。本发明旨在通过为轴(9)配备用于检测作用于该轴的轴向力（axial force）(F)的测量单元（measuring unit）(10)，实现该装置的安全运行。本发明涉及一种纤维材料处理装置，该装置具有两个设置于壳体(1)内的研磨间隙(2、3)，纤维材料径向流经该间隙。每个间隙均由绕旋转轴(8)转动的处理刀具(5)与静止处理刀具(4)构成，其中，两类处理刀具(4、5)分别固定于基板(6、7)，二者均呈旋转对称形状且彼此同轴布置。两个转动式处理刀具(5)固定于由可旋转安装的轴(9)驱动的共用基板(7)，并设置于两个静止处理刀具(4)之间。转动式基板(7)轴向可移动地固定于轴(9)，且通过至少一块静止基板(6)的轴向位移，可调节研磨间隙(2、3)的宽度。本发明旨在通过为轴(9)配备用于检测作用于该轴的轴向力(F)的测量单元(10)，实现该装置的安全运行。
