The headbox receives diluted pulp slurry from the approach flow system and distributes it uniformly across the full width of the forming wire. It controls the velocity, consistency, and turbulence of the fiber suspension to ensure proper sheet formation with consistent basis weight and fiber orientation.
Typical reference ranges include a working width of 2.5–10 m, slice opening range of 5–30 mm, design pressure of 0.8–1.2 kPa, jet velocity of 300–1200 m/min, consistency of 0.3–1.5%, and operating temperature of 40–70°C. These are directory references and must be confirmed for the specific model.
Materials on file include stainless steel 316L, polyurethane, ceramic coatings, and EPDM rubber seals. The material grade for corrosion resistance is SS316L or duplex, per ASTM A240. Verify material certifications with the supplier.
The headbox maintains a uniform pressure across the width and uses an adjustable slice opening with a tolerance of ±0.05 mm. Turbulence generators prevent fiber flocculation, ensuring even distribution. The jet velocity and consistency are controlled to achieve consistent basis weight.
