ABSTRACT:
A refiner head assembly of the type suitable for use in disk refiners, such as those employed in paper pulp processing. The assembly includes a backing head and a refining disk. The disk mounts reversibly between a pair of radially spaced, circumferentially extending flanges upstanding from one face of the head using, for example, a beveled tongue and groove arrangement. The disk has both of its opposed side faces equipped with working surfaces adapted for disk refining. Thus, since the disk is reversible, one can use such a disk for twice as long a duty life as a disk with but one side face equipped with a working surface.
