Abstract
A refiner plate defines an axis of rotation that further defines variations in azimuth. The refiner plate includes an annular body portion and a plurality of azimuthally spaced-apart elongate bars projecting from the body portion. The bars have top surfaces having elevations that vary as functions of azimuth. A disc refiner further defines a direction of rotation of the refiner plate. Preferably, each top surface slopes downwardly in the direction opposite the direction of rotation, to provide for relief. Preferably in addition, each bar has a side intersecting the respective top surface that leans forwardly in the direction of rotation, to provide for attack.
