The Role of Wedge Wire Screens in the Pulp and Paper Industry

In the highly demanding pulp and paper industry, efficient fiber recovery and contaminant removal are essential for maintaining production speed and product quality. The wedge wire screen has become the gold standard for these processes due to its high open area and mechanical durability.

At Johnsonslot, we engineer custom filtration components that help mills reduce downtime and optimize energy consumption through advanced V-wire technology.

1. Pressure Screen Baskets for Pulping

The heart of the screening process is the pressure screen. Our wedge wire screen baskets are designed to handle high-consistency pulp while precisely removing shives, sticks, and plastics.

• Precision Slots: We offer slot tolerances as fine as 0.1mm to ensure maximum purity of the pulp.

• Increased Throughput: The V-wire profile minimizes friction, allowing for higher flow rates than traditional perforated plates.

2. Dewatering and Fiber Recovery

Water management is a significant cost factor in paper mills. Utilizing a wedge wire panel or cylinder in dewatering machines allows for:

• Maximum Fiber Retention: The sharp-edged V-wires effectively capture fibers while letting water pass through freely.

• Self-Cleaning Action: The inwardly enlarging slots prevent long fibers from plugging the screen, ensuring continuous operation.
