Abstract
A pulp fluidizer and pulp disc refiner apparatus and process. Paper pulp stock of either low (3-8%) or medium (8-15%) fiber consistency is fed from the fluidizer portion of the apparatus to the disc refiner. The construction is such that the outlet of the fluidizer is contiguous to the inlet of the refiner. This geometrical relation permits the de-flocculated pulp from the fluidizer outlet to be fed substantially immediately to the refiner inlet, prior to its naturally occurring reversion to a flocculated state. By providing the input of the disc refiner with de-flocculated paper pulp stock, higher pulp stock consistencies can be worked by the disc refiner, resulting in savings of emergy, equipment and space. Three embodiments of the invention are described.
