HIGH CONSISTENCY DAMLESS REFINER PLATE FOR WOOD FIBERS

摘要

The refiner plate of this invention has a pattern of interlocking or nested elements having a "I"s "T"s, "S"s, "L"s, "F"s, "E"s, or "H"s shape which form channels. The body of the elements forms the refiner bars (50) which hold the fibers as they move between the refiner plates in a disk refiner (20). The patte rn of elements retard the flow of fibers while at the same time providing a large o pen area for steam to pass through the refiner disks (28, 30). The segments making u p the elements produce a refiner bar (50) which is reinforced for higher strength. The shape of the elements has an increased edge length exposed to the flow of fibers.
