BtoSlot Wedge Wire Screen: Features, Advantages and Working Principle

BtoSlot wedge wire screens are precision-engineered filtration and separation components, widely used in industrial processes such as screening, filtration, dehydration, classification, and desliming. Designed for performance and durability, our wedge wire screens combine high mechanical strength, exceptional slot precision, and versatile flow configurations, making them ideal for a wide range of industries including mining, water treatment, petrochemical, food processing, and agriculture.

Structural Features

A wedge wire screen consists of two main elements:

• Surface Profiles (Working Wires): V-shaped wires that form the filtration surface, wound or laid in parallel.

• Support Profiles (Backing Rods): Typically triangular or round rods that provide mechanical support and define the structural strength.

These components are welded together using advanced automated welding technology to ensure a high degree of uniformity in slot spacing and screen integrity.

BtoSlot manufactures both cylindrical (radial) and flat panel wedge wire screens with various flow directions:

• Flow-In-to-Out: Liquid enters from the inside and flows outward. Ideal for internal pressure filtration.

• Flow-Out-to-In: Liquid flows from the outside inward. Common in applications requiring backwashing or blow-washing.

Working Principle

The screen’s filtration function is determined by the precisely engineered slots between the V-shaped surface wires. As liquid flows through the screen:

• Particles larger than the slot width are retained on the surface.

• The wedge-shaped slot design minimizes clogging and allows for easy removal of particles.

• Backwashing or reverse flow can quickly clean the screen, restoring performance.

This allows for continuous operation, low maintenance, and consistent filtration accuracy.

Key Advantages of BtoSlot Wedge Wire Screens

✅ 1. Precision Slot Control

Customizable slot sizes (from 0.02 mm and above) ensure high filtration accuracy, meeting exact customer specifications.

✅ 2. Superior Strength & Durability

Constructed from high-grade stainless steel (SUS304, SUS316, SUS316L), our screens can withstand high pressure differentials and mechanical loads without deformation.

✅ 3. Corrosion & Heat Resistance

With excellent resistance to acid, alkali, and extreme temperatures, BtoSlot wedge wire screens perform reliably in the most demanding environments.

✅ 4. Large Open Area & High Flow Capacity

The V-wire structure increases open area and allows for high throughput with minimal pressure drop, improving overall efficiency.

✅ 5. Anti-Clogging & Easy Maintenance

The smooth surface and wedge-shaped slot geometry reduce particle buildup and enable efficient cleaning, especially through backwashing or blow-washing.

✅ 6. Flexible Design Options

We offer fully customizable products in terms of wire profile, support rod type, diameter, length, slot size, and end fittings—tailored to your specific application.

✅ 7. Cost-Effective & Reusable

Unlike disposable filters, wedge wire screens are durable, washable, and reusable, reducing long-term operational costs.
