4400/600 Fourdrinier Multi-Cylinder Paper Machine Production Process Flow

Leizhan’s 4400/600 fourdrinier multi-cylinder paper machine is a high-efficiency paper making device designed specifically for producing high-strength corrugated paper of 90-160g/m². The machine is composed of multiple functional departments, including the wire part, press part, dryer part, sizing machine, and winding part. This modular design not only ensures efficient collaboration among the components but also provides convenience for maintenance and operation.

4400/600 Fourdrinier Multi-Cylinder Paper Machine Production Process Flow

1. Pulp Input: A hydraulic headbox is used to evenly distribute the pulp, ensuring consistent paper formation.
2. Forming Stage: In the 21-meter-long wire section, the pulp is dewatered to form wet paper, creating the initial paper structure.
3. Pressing Process: The paper undergoes two large-diameter presses (Ø1500mm) to further remove excess moisture and improve paper strength.
4. Drying Treatment: Multiple Ø1800mm and Ø1500mm drying cylinders quickly and effectively dry the wet paper to the required moisture content.
5. Winding Stage: Finally, the finished product is wound into rolls by a paper winding machine, ready for subsequent packaging and transportation.
