Wedge wire screen is a metal mesh element widely used in screening, filtration, dehydration and desliming operations for sieving and filtration. It has high strength, rigidity and load carrying capacity and can be made into a variety shapes of rigid screening filters.
The wedge wire screen consists of surface profiles and support profiles. Surface profiles, usually v-shaped wires, are wrapped and welded onto support profiles. The distance between the surface profiles is controlled very accurately, as it forms the slot through which the filtrate flows. The direction of the flow is determined by the position of V-shaped wires (surface profiles) in relation to the support profiles. Wedge wires screens are either flow-out-to-in or flow-in-to-out.
Wedge wire screens are generally made of V-section wires to form slot openings which widen inwardly so that materials tend to pass through the screen. The high open area of wedge wire screen provides excellent permeability properties. Our wedge wire screens can be fabricated with materials that are resistant to corrosion and abrasion, or in combination with polyurethane frame for easy installation while reducing labor intensity and machine downtime. They are suitable for many screening applications in a variety of industries including mining, coal, oil, fertilizer, grain, salt and environmental protection.
