1. What is Wedge Wire Screen?

Wedge Wire Screen is produced through the method of electric resistance welding,

wires with profile profiles are welded to support rod at 90 degrees.

The distance between two profile wires is the slot opening, which is the filtration rate.

Minimum slot is 20um.

The structure is FOTI(flow-out-to-in) & FITO(flow-in-to-out).

2.Specification of Wedge Wire Screen?

• Minimum slot: 0.02mm(20um)
• Mimimum diameter: 16mm
• Maxmum Length: 6000mm
• Perfect roundness
• Very smooth wire surface
• Profile wire size: 0.75x1.5mm, 1.0x2.0mm, 1.5x2.5mm, 2.0x3.0mm, 2.0x4.0mm, 3.0x5.0mm...
• Support Rod size: 2.0x3.0mm, 3.0x5.0mm, 5.0x8.0mm

4. Application of wedge wire screen?

• Coatings
• Chemical
• Petrochemical
• Pulp and paper
• Food and beverage​
• Solid-liquid separation
• Waste water treatment
• Mineral and aggregate processing

5. Advantages of wedge wire screen?​

• High-precision slot opening: Minimum Slot opening is 20 microns.
• Smooth Surface Filtration: very good smooth filtration surface, which reduce mechanical wear.
• Non-clogging construction: The v-shaped wires and support rods is welded together by automatic resistance welding, which ensures a two- point contact between the particles and the slot,which minimizes clogging of near size product.
• Strong construction: for most applications the wedge wire is self-supporting because of the welding at each intersection and can therefore withstand high pressure(Psi) and heavy loads.
