Components for tissue machinery
Headboxes play a crucial role in paper machinery, offering efficient and reliable performance to meet various production requirements. The hydraulic headbox is well-suited for a wide range of paper machines with speed spanning from 400 to 1800 m/min. The pulp is introduced into the headbox and passes through a conical header that distributes the pulp uniformly across the width of the machine. This even distribution is vital for the consistent thickness and quality of the paper sheet. Before the pulp enters the step diffusers, dilution water is injected into the pulp stream. This process helps in adjusting the consistency of the pulp, allowing for precise adjustments to the cross-direction basis weight of the paper. The ability to fine-tune the pulp consistency at this stage is essential for achieving uniform paper density and quality across the entire width of the paper.
Hydraulic headbox is suitable for .
| Basis Weight | 13-25g/m² |
| Working Width | 1880-5600mm |
| Headbox Pond Width | 1880-5600mm |
| Working Speed | 400-1800m/min |
| Consistency | 0.15-0.20% |
| Max. Recirculation Flow | 5-10% |
| Lip Opening Adjustment | 15mm |
- The headbox is specially designed to handle various pulp types and machine speeds with custom-designed turbulence strengths with varying structures and intensities.
- The stock inlet pipe features a conical isobaric design, ensuring uniform and stable stock pressure across the width of the nozzle while controlling pulp re-flocculation and reducing energy consumption.
- The angle of the nozzle is adjustable, making it convenient to use and allowing for precise modifications to meet specific production needs, ensuring high quality paper output.
- Manual control of top-lip shifting that can be adjustment according to the speed of the machine
- Constructed from 304 stainless steel, the headbox’s body and its surfaces in contact with stock are electropolished to a mirror finish to prevent pulp adhesion and minimize scaling.
