​​Wedge Wire Screen Working Principle And Advantages​

Wedge wire screens are precision-engineered filtration components essential for high-efficiency solid-liquid separation across mining, water treatment, and oil/gas industries. Their unique structural design enables superior performance where conventional screens fail.

Structural Engineering

Core Components

• Surface Profiles: V-shaped wires creating self-cleaning slots

• Support Profiles: Circular cross-rods with tensile strength ≥650 MPa

• Laser Welding: ≤0.05mm heat-affected zone (HAZ) for joint integrity

Filter direction

Performance Advantages

1. Precision Filtration

• Slot width control: 0.10-3.00mm (±0.02mm tolerance)， ensure the effective retention of filter medium.

• Slot uniformity: CV≤1.5% across screen surface

• Wedge wire screen has a larger circulation area compared with other screens.

2. Anti-Blocking Design

• V-wire apex creates shear forces that dislodge particles

• Wedge wire screen has a larger circulation area compared with other screens

3. High Flow Capacity

4. Extreme Durability

• 304,316L with strong corrosion resistance and high temperature resistance performances and can totally adapt to various harsh environment

• It has high mechanical strength and can withstand high pressure drop.

Industry Applications
