Embodiment Construction

[0046] according to figure 1 , in the housing of the grinding device, the grinding gap 4 is formed by a grinding surface that is fixed and connected to the housing and a grinding surface that rotates around the axis of rotation 15 . In this case, two annular grinding surfaces (processing surfaces) run parallel to one another, wherein the distance between the two grinding surfaces can usually be adjusted.

[0047] In this case, the rotating grinding surface is moved in the direction of rotation via a shaft 16 mounted rotatably in the housing. The shaft 16 is driven by a drive also arranged in the housing.

[0048] In the exemplary embodiment shown, the fiber suspension 1 to be ground enters the grinding gap 4 between the two grinding surfaces through the inlet through the center. However, it is also possible to realize the input through an opening in the fitting.

[0049] The fiber suspension 1 passes radially outwards through the cooperating grinding surfaces and exits the ...

Abstract

The invention relates to a method for producing an accessory (2, 3) for processing a water-based suspended fiber material (1) in a processing gap (4), said accessory being composed of a The base body (5) of the machining element (6) is formed. In order to reduce the manufacturing effort, it is provided that the processing element ( 6 ) is at least partially coated with a liquid or solid material layer by layer and that a physical or chemical hardening or melting process is carried out here.

Description

technical field [0001] The invention relates to a method for producing a fitting for processing water-based suspended fiber material in a processing gap, the fitting consisting of a base body with processing elements directed towards the gap. [0002] The invention also relates to a fitting for processing water-based suspended fibrous materials in a working gap delimited by two working surfaces rotating relative to one another and formed by fittings, the fittings being formed by a base body, The basic body has an elongated machining element pointing towards the gap and extends radially along at least one direction component, and the fitting is produced according to the method according to the invention. Background technique [0003] Such fittings shall be suitable for mechanical processing of suspended fibrous material. This preferably grinds the paper fibers, separates dirt and fibers and impregnates, ie dissolves, the fiber clusters. The accessories are installed, for ex...
