Abstract
A refining member for a pulp refiner comprising a refining body with a refining surface comprising refiner bars separated by refiner grooves and teeth. Each of the refiner bars extend from a radially inward position on the refining surface to a first radially outward position on the refining surface, and the teeth extend to a second radially outward position on the refining surface. The second radially outward position is nearer to an outermost part of the refining body than the first radially outward position. The refiner bars are adapted to refine wood fibers, and the teeth are adapted to break up fiber bundles.
