4400mm Fourdrinier Corrugated Paper Machine for High Strength Packaging

The paper mill machine described in this 4400/600 technical specification is engineered for high‑strength corrugated paper with a net trim of 4400 mm. This paper making machine achieves 418 t/d at 120 g/m², 550 m/min, and features a 21‑meter wire section with cantilever wire change, a hydraulic headbox, and a two‑level wire/press layout. The paper production equipment includes a vacuum pickup, two large‑diameter press rolls with blind drilling and grooving, 37 φ1800 dryer cylinders, 8 φ1500 VAC cylinders, a film‑type size press, and a reel spool reeling machine. All rolls are dynamically balanced to G1.6. The paper industry machinery also features a cordless sheet threading system, central oil lubrication, and a PLC‑controlled hydraulic station, ensuring reliable operation for packaging paper mills.

Technical Highlights of Our Paper Manufacturing Machine:

Forming Section: 21 m wire length; ceramic dewatering elements; vacuum couch roll (φ1000 mm, double chamber, 60% open area).

Press Section: Two vacuum suction transfers + two large‑roll presses (320 kN/m design line pressure); 8 felt suction boxes.

Drying Section: 37 φ1800 cylinders (6 chrome‑plated) + 8 φ1500 VAC cylinders; G2.5 dynamic balance; group gear drives.

Size Press & Reel: Inclined roll film size press (φ1250/1255 mm, 80 kN/m); reel spool winder (φ1100 mm reel spool, 6 reeling rolls).

Drive System: 40 AC drive points, total 2243 kW, sectional digital control (ABB ACS880 compatible).

This complete paper mill line integrates all auxiliary systems – hydraulic, lubrication, compressed air, and cordless paper leading – into one coherent design. Our paper processing line meets demanding corrugated medium requirements with low energy consumption (dryness: 22% off wire, 46‑48% into dryers, 92% final). We provide full technical documentation, pre‑assembly, and field support. Contact us to upgrade your paper making line with this high‑efficiency, robust 4400/600 machine. leizhanworld@gmail.com
