REVERSIBLE DISK REFINER PLATES

摘要

REVERSIBLE DISK REFINER PLATES Refining plates for disk-type refiners are manufactured with a working surface on each side thereof so that they can be turned over for reuse after one working surface has worn away. Special provision is made for mounting these plates to protect the unused working surfaces while preventing bypass flow of stock through the grooves in each working surface which is not being used, and also to compensate for a worn-out working surface when the other side of the plate is being used. Identical plates may be used on both stator and rotor; alternatively, a double-sided rotor plate can be used in combination with a hub on which it is mounted for replacement whenever the stator plates are turned over or replaced.
