For Sale: Second-Hand 4400/400m Single Fourdrinier Paper Machine
This high-performance single Fourdrinier paper machine, with a specification of 4400/400m, is well-suited for producing high-strength corrugated paper in the range of 80-160 grams. It comes with a complete set of supporting equipment, ensuring stable operation and reliable performance, making it an ideal choice for paper production enterprises looking to optimize cost and expand production capacity.
Core Configuration & Technical Details
- Forming Section: The wire length reaches 20 meters, and the vacuum couch roll has a diameter of 1000mm, adopting a top-forming design for efficient paper web formation. The frame is fully covered with stainless steel, enhancing corrosion resistance and extending the machine’s service life. Key components in this section include a hydraulic headbox (produced by Zhuji, Zhejiang in 2017), a pressure screen (manufactured by Yunda) installed in front of the wire, and a wire front pump (produced by ANDRITZ)—all of which are renowned for their precision and durability.
- Press Section: Equipped with vacuum suction rollers and pick-up rollers sized 700×5100×5700mm, along with two large rollers (diameter 1500×5000×5700mm) featuring upper and lower double blind holes. This configuration effectively removes moisture from the paper web, improving paper tightness and strength.
- Drying Section: Comprises 24 dryers with dimensions of 1800×5000×5700mm, arranged in five-piece drying cylinder sets and adopting closed transmission to ensure uniform heat distribution and efficient moisture evaporation. Additionally, it includes one middle diagonal size press roller (diameter 900×5000×5700mm) and 14 rubber rollers (1800×5000×5700mm), which further optimize the drying effect and paper surface quality.
- Reeling & Winding Section: Features one pope reel (equipped with 6 rollers) and one underfeed winder with a maximum speed of 1000 meters per minute. This setup enables smooth, high-speed reeling and winding, meeting the requirements of continuous large-batch production.
Complete Supporting Systems
The machine is fully equipped with reducers, motors, and a comprehensive vacuum system (including water ring pumps and turbine fans), all of which are in good working condition. No additional major investments in supporting equipment are required, allowing for quick commissioning and production after purchase.
