UET TECH Fourdrinier Papermaking Machine Solutions
UET TECH Fourdrinier Papermaking Machine Main Components
The stable operation of a Fourdrinier papermaking machine depends on the coordinated operation of its core components. These components have clear divisions of labor, from pulp mixing to finished product winding, and are closely linked, directly affecting paper quality and production efficiency.
Headbox
Responsible for evenly conveying pulp to the Fourdrinier wire. Its internal structure ensures smooth pulp flow, precisely controlling flow and pressure to ensure a consistent thickness of pulp as it is spread across the wire, fundamental to paper sheet formation.
Forming Fabric
Like a circulating filter, it carries the pulp and performs initial dewatering. Fibers intertwine on the fabric to form a wet paper sheet. Its air permeability and operational stability directly impact the quality of the formed paper sheet.
Pressing Rollers
Using the squeezing action of upper and lower rollers, the paper is further dehydrated. This action also strengthens the paper fibers, increasing its strength and playing a key role in improving paper dryness.
Pressing Felt
This circular felt, composed of multiple layers of fabric, covers the surface of the press rolls. It transmits pressure and absorbs moisture during the pressing process, while also protecting the wet paper from damage. Its air permeability and elasticity must be tailored to the paper grade’s characteristics.
Drying Cylinder Group
The steam-heated cylinder evaporates the remaining moisture from the paper through heat transfer. Multiple drying cylinder groups operate sequentially, gradually drying the paper to the desired dryness and ensuring a stable paper shape.
Calenders
Composed of multiple rollers, these machines apply pressure to smooth the surface of paper sheets. This reduces surface roughness, improves printing suitability, and ensures the paper is more suitable for specific applications.
Paper Winding Machine
Rolls dried paper into neat rolls. Adjusts the winding tension based on the paper’s characteristics, ensuring a tight roll with a smooth end surface for easy storage and processing.
Why choose UET TECH Fourdrinier paper machine as your solution?
Key components such as the headbox and press rolls are independently developed, enhancing adaptability and reducing the likelihood of failure. Combined with an intelligent control system, the paper basis weight deviation is controlled within ±1%, consistently improving paper quality.

Fourdrinier Paper MachineFrequently Asked Questions
A: It is suitable for producing newsprint, fine paper, and packaging paper. Its Fourdrinier wire structure ensures even fiber distribution, resulting in excellent paper strength and uniformity. It is particularly well-suited for mass production of low- to medium-weight papers and meets most general printing and packaging needs.
A: The Fourdrinier papermaking machine relies on the Fourdrinier wire section for dewatering, resulting in higher paper uniformity and strength, making it suitable for high-quality paper. The rotary papermaking machine, on the other hand, is simpler in structure and slower in speed, producing thicker paper weights but slightly less uniform. It is also more cost-effective and is primarily used for packaging board and other paper products.
A: A typical Fourdrinier machine has a speed of 500-1200 m/min, depending on the paper type and machine specifications. Thin papers (such as newsprint) are produced faster, while thicker paperboard is produced slower. Advanced machines can improve stability through wire optimization.
A: Small and medium-sized units take approximately 2-4 months, while large lines take 6-10 months. This includes equipment installation, piping connections, and electrical commissioning. This time may be longer if there are many customized components or the site is complex.
A: They primarily process wood pulp, waste paper pulp, and straw pulp. They are well-suited to pulps with moderate fiber lengths. When processing waste paper pulp, enhanced screening and purification are required to prevent impurities from affecting wire operation and paper quality.
A: Not very high. The main costs are in wire cloth replacement, roller maintenance, and drive system maintenance. Regular cleaning of the wire and inspection of bearings can reduce the failure rate. Compared to a rotary wire machine, maintenance is slightly more complex due to the larger number of components, but the machine has a longer lifespan.
A: If your budget is limited, consider a used machine in good condition. Check the wire wear, transmission accuracy, and control system aging. It's best to have a professional evaluate it to avoid high subsequent repair costs.
A: Slightly more, due to the Fourdrinier's higher speed and the need for additional equipment (such as a vacuum dewatering system). However, technologies like variable frequency motors and waste heat recovery can narrow the energy consumption gap, and the higher efficiency can even improve energy consumption per unit of output.
