<p>The present invention relates to a refining apparatus of disc-type. The same consists of a shaft (1), having a rotatable disc (2) equipped with a set of refiner elements (4) and a stationary disc (3), also this having a set of refiner elements (5). Characteristic of the invention is that, between the stationary refiner elements (5) and the stationary disc (3), one or more axially deformable chambers (6) are arranged. These are filled with a preferably constant amount of an incompressible hydraulic medium, which is allowed to move within or between the chambers. Thus, the set of stationary refiner elements (5) can move angularly in order to adjust itself tangentially in parallel to the set of refiner elements (4) of the rotatable disc. Simultaneously, the incompressibility of the hydraulic medium prevents the set of stationary refiner elements (5) from moving in a purely axial direction and thereby impairing the axial stiffness of the machine. According to a described embodiment, with the set of stationary refiner elements being fixedly clamped to the stationary disc at the inner periphery thereof, also the radial parallelism of the disc gap can be adjusted, by adapting the amount of hydraulic medium in the deformable chambers.</p> |
