<p>A plurality of axially spaced and axially resiliently flexible annular refining disks in a refiner working chamber have stock flow equalizing ports through the disks, and the pressure on opposite sides of the disks is balanced as by pressure balancing vanes associated with the ports. The vanes may be mounted on the disks at the ports or may be carried by rotor structure and aligned with the ports.</p> |
