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 and non-rotatable refiner disks which are axially movable within a refiner, the rotatable disk being mounted on a torque transmitting section of a shaft and the non-rotatable disk being mounted against rotation on a plurality of supporting elements. In order to control the number of refiner bar crossings, the housing may be opened and a desired number of refiner disks, both rotating and nonrotating, may be loaded into the refining chamber on the shaft and the support elements, respectively. |
