The pulp and paper industry demands high-efficiency systems for fiber separation, filtration, and water recovery. As one of the most critical components in achieving these goals, wedge wire screens offer superior durability, efficiency, and adaptability across all stages of the pulp production process.
The pulp and paper industry demands high-efficiency systems for fiber separation, filtration, and water recovery. As one of the most critical components in achieving these goals, wedge wire screens offer superior durability, efficiency, and adaptability across all stages of the pulp production process.
At BTOSLOT, we specialize in manufacturing high-performance wedge wire screen products designed to meet the rigorous requirements of pulp and paper mills around the world.
Why Wedge Wire Screens Are Ideal for Fiber Separation
Wedge wire screens feature triangular-shaped wires welded to support rods, providing precise slot openings that maximize open area and ensure effective solid-liquid separation. Their design enables:
High throughput with minimal pressure drop
Non-clogging surface for easier cleaning
Customizable structures for various machinery
Superior wear and corrosion resistance
Extended service life under continuous industrial use
Key Applications in the Pulp & Paper Industry
1. Pulp Screening and Cleaning
Wedge wire screens are used to remove knots, bark, wood chips, sand, and other contaminants from the pulp during initial preparation. This ensures fiber purity and protects downstream machinery from damage.
2. Pulp Thickening
Our wedge wire screen cylinders increase pulp fiber concentration by removing excess water, making the process more energy-efficient and reducing handling costs. They're often used in both virgin fiber and recycled fiber lines.
3. Pressurized Screening
Within pressurized screening systems, wedge wire screens handle the separation of usable fibers from rejects, helping control pulp consistency and improve process performance.
4. Centrifugal Screening
BTOSLOT screens support centrifugal separation units by effectively removing coarse impurities and oversized particles, enhancing the cleanliness of the pulp before forming stages.
5. Dewatering Systems
Before the pulp reaches the paper machine, wedge wire dewatering screens remove excess water, reducing energy consumption during drying and helping maintain proper sheet formation.
6. White Water Recovery and Recycling
Fiber recovery from white water is essential for cost-saving and sustainability. Wedge wire screens enable closed-loop water usage, significantly reducing water waste and operational costs.
Custom Solutions from BTOSLOT
Every paper mill has unique needs. That’s why BTOSLOT offers:
Custom slot sizes from 0.05 mm to 10 mm
Diameters ranging from Ø100 mm to Ø2500 mm, lengths up to 6.5 meters
Material options including SS304, SS316, 316L, and other corrosion-resistant alloys
Support drum and flange customization for seamless integration into existing systems
We collaborate with engineering and purchasing teams to deliver tailored wedge wire screen solutions that maximize efficiency and minimize downtime.
