Screen Plate

Product Character

1. Bar type Screen Plates - For Tissue Pulp Bar type Screen Plates are primarily used in tissue paper pulp production and are typically found in machines of a more traditional design. Their function is to precisely remove contaminants larger than the slot size, such as stickies, dirt specks, and sand particles, to ensure pulp cleanliness. Due to the high quality and inherent cleanliness of tissue pulp, these screens generally benefit from a longer operational lifespan.
2. Hole type Screen Plates - For Defibering Hole type Screen Plates are integrated as part of an assembly with an impeller for use in the defibering process (pulper). Defibering is the operation of reducing waste paper back into individual pulp fibers, serving as the very first stage of the entire stock preparation line. Depending on the specific pulper design, the hole sizes typically range from 2.4mm to 20mm. The main function of these plates is the removal of heavy and light junk (rejects), ensuring that only clean fibers move on to subsequent processes. The screen holes are generally round, but the aperture design may feature specialized geometries such as stepped holes (multi-size), conical holes, or turbulence holes. These advanced designs facilitate smooth pulp flow while providing the necessary strength and rigidity for the plate.
