Paper Pulp Equipment Air Cushion Headbox
Our air cushion headbox is a core essential device for paper forming in papermaking production lines. Compared with ordinary headbox equipment, this machine features uniform pulp flow distribution, stable operating performance and strong anti-foam ability. It adopts a scientific three-stage diffusion and double homogenizing roller structure, which effectively eliminates pulp flow fluctuation. All parts in contact with pulp are finely polished to avoid fiber adhesion, ensuring flat and high-quality paper web forming and long-term stable continuous operation.

This air cushion headbox adopts professional square cone pipe pulp feeding design, matched with organic glass three-stage step diffuser and double homogenizing rollers to realize even pulp dispersion. The two homogenizing rollers are made of stainless steel pipes with opening rates of 40.3% and 50.8% respectively, meeting different pulp homogenizing demands. Equipped with front wall overflow device and internal spray pipes, the equipment can clean the inner wall and remove foam in real time, preventing fine fiber adhesion and keeping the box interior clean at all times.
In terms of material configuration, all components contacting pulp are made of high-quality 316L stainless steel, finely polished with a surface roughness of Ra0.4μm. The main box body and square cone pipe are welded with 06Cr19Ni10 stainless steel plates, and all fasteners for the fourdrinier wire section system adopt 1Cr18Ni9Ti stainless steel material. All pulp-contact surfaces pass cotton ball inspection with no fiber hanging phenomenon, which greatly improves the durability and operational stability of the equipment.
Besides, the equipment supports flexible adjustment of lip opening and local fine-tuning. The upper lip plate can be adjusted vertically and horizontally, which can accurately control the paper web forming effect and adapt to different papermaking production requirements. With reasonable structural design, reliable material selection and convenient operation and maintenance, our air cushion headbox is widely suitable for various paper mill production scenarios.
If you are looking for high-stability, high-precision and durable paper forming machine equipment for your paper production line, our air cushion headbox is your ideal choice. We provide reliable industrial-grade papermaking equipment and professional supporting services for global paper mills.
