Abstract
An improved multiple disk refiner of the type employing a rotatable hub which is mounted for rotation within a housing, and a plurality of spaced refiner rotor disks and additional disks in interleaved relation with each other and defining passages through which a stock suspension to be refined can be passed. Relative rotational movement occurs between the rotor disks and the additional disks. The invention is particularly concerned with an improved rotor structure which is mounted on the hub for rotation therewith, and resilient coupling means which connect the rotor with the rotor disks. The coupling means include a resiliently deformable elastomer which is arranged to deform in a shearing mode thereby permitting increased axial deflection of the rotors and operation at a higher intensity level.
