Date Aug. 27, 1987.A paper stock refiner provides low intensity treatment of pulp fiber to increase the strength characteristics of the pulp while reducing the specific energy required through increasing the number of refining surfaces. The number of refining surfaces is accomplished by providing a plurality of rotatable (30) and non-rotatable (36) refiner disks which are axially movable within a refiner, the rotatable disks being mounted on a torque transmitting section (28) of a shaft (26) and the non-rotatable disks being mounted against rotation on a plurality of supporting elements (44). In order to control the number of refiner bar crossings, the housing (12) may be opened and a desired number of refiner disks, both rotating and non-rotating, may be loaded into the refining chamber (16) on the shaft and the support elements, respectively.</p> |
