The wedge wire screen is a metal mesh element widely used in screening, filtration, dehydration, and desliming operations for sieving and filtration. Crafted through precise welding of V-shaped profiles onto support profiles at designated intervals, these screens boast continuous gaps that efficiently filter liquids while entrapping larger substances. Their versatility and varied applications make them vital in numerous industries, ensuring optimal performance in sieving and filtration operations.
Wedge Wire Screens Flowing Direction:
Wedge wire screens present diverse flowing directions crucial for specific applications--FOTI (Flowing Outside to Inside) and FITO (Flowing Inside to Outside)
Types of Wedge Wire Screen:
-Radial External Wedge Wire:
--FOTI: Ideal for standard applications with precision openings and cost-effective production.
--FITO: Offers reversed flow, beneficial for backwashing procedures.
- Radial Internal Wedge Wire:
--Only available in FITO, this type enables a smooth internal screen surface, facilitating cleaning and proving economical for small-quantity productions.
- Axial Internal and External Wedge Wire Variants:
Different constructions providing distinct advantages such as smooth surfaces, effective dewatering, and enhanced strength.
Wedge Wire Screen Open Area Calculation:
Determining the open area percentage proves crucial in predicting flow capacity,
Open Area = ( Slot Opening / (Wire Width + Slot Opening)) × 100
