The Working Principle of Wedge Wire Screens

Wedge wire screens, also known as profile wire screens or Johnson screens, are designed for mechanical filtration in solid-liquid separation, dewatering, and particle sizing applications.

They are made by welding V-shaped (wedge) profile wires onto support rods at precise intervals, creating accurate and uniform slots. This design:

• Allows liquid to pass through while retaining solids.

• Prevents clogging due to the self-cleaning V-shaped wire profile.

• Offers high mechanical strength and durability.

How Wedge Wire Screens Work

When a slurry, wastewater, or process liquid flows across the wedge wire screen:

1. Liquid passes through the precisely spaced slots.

2. Solids are retained on the screen surface.

3. The retained solids can be removed continuously or periodically, depending on the system design.

Slot Size Customization: At BtoSlot, slot sizes can range from 20 microns to several millimeters, allowing for precise filtration tailored to your process needs.

Flow Efficiency: The open area ratio and slot profile are engineered to minimize pressure drop and maximize throughput.

Main Types of Wedge Wire Screens

Flat Panels

• Rectangular panels with welded wedge wires and support rods.

• Common in mining, food processing, and wastewater treatment.

• Easy to install in screening equipment and filter systems.

Cylindrical Screens / Wedge Wire Screen Pipes

• Hollow cylinders used in water wells, oil wells, and industrial filtration.

• Designed to handle high pressure and large flow rates.

• Available in both internal and external flow designs.

Baskets

• Custom-made to fit centrifuges, vibrating separators, or other equipment.

• Ideal for high-capacity solid-liquid separation.

Curved Screens (Sieve Bends)

• Used for dewatering, especially in sugar processing, mining slurry, and pulp screening.

• Curved profile enhances screening efficiency.

Key Advantages of Wedge Wire Screens

Compared to conventional wire mesh or perforated metal sheets, wedge wire screens offer:

• High Filtration Efficiency – Uniform slot sizes ensure accurate particle retention.

• High Mechanical Strength – Resistant to collapse, wear, and corrosion.

• Customizable Design – Slot size, open area, and wire profile can be tailored.

• Self-Cleaning Action – V-shaped profile prevents clogging and reduces downtime.

• Long Service Life – Stainless steel or specialty alloys ensure years of reliable operation.
