Abstract
A method is provided for processing wood fibers comprising providing a refiner comprising a first refining member including first refiner bars and a second refining member including second refiner bars. The first refining member may be spaced from the second refining member to define a refining space therebetween. The first and second refiner bars may be separated by refiner grooves. The method further involves rotating at least one of the first refining member or the second refining member, and supplying a slurry of wood pulp comprising wood fibers to the refiner such that the wood pulp slurry passes through the refining space. The one refining member is rotated at a power level sufficient to create a refining intensity within the refining space of at least about 3 Newtons.
