Wedge Wire Screen Element — Continuous-Slot Vee-Wire Cylinder
The wedge wire screen element is a continuous-slot Vee-wire cylinder, 25 mm to 600 mm outside diameter, with slot openings from 0.05 mm to 6 mm in SS316L or SS304. It delivers up to 60% open area and non-clogging flow for mining, water treatment and pulp mill streams carrying fibrous or high-solids load.
Product Overview
CONTINUOUS SLOT 0.1MM-6MM
Vee-wire profile welded to support rods. High open area for maximum flow. Non-clogging for high-solids streams.
KEY DIMENSIONS
Where It Is Used
- Mining and minerals: Screens slurry, tailings and dewatering duty where the V-profile sheds coarse solids instead of blinding the way punched plate does.
- Water treatment: Used as intake, backwash and media-retention screens that hold resin or sand while passing a high flow at low pressure drop.
- Pulp and paper: Fibre recovery and white-water screening benefit from continuous slots that pass long fibres without wedging them into holes.
- Chemical processing: Catalyst retention and resin-bed support screens rely on the ±0.05 mm slot tolerance to keep expensive media in place.
- Food and beverage: Starch, sugar and CIP circuits use polished SS316L wedge wire because the smooth slot face is fully cleanable between batches.

WEDGE WIRE SCREEN ELEMENT vs Perforated plate screen
| Wedge wire screen | Perforated plate screen | |
|---|---|---|
| Open area | Up to 60% open area on the same outside diameter, because the profile wires are narrow and evenly spaced. | Typically 25% to 40% open area, limited by the minimum ligament between punched holes. |
| Clogging behaviour | The V-shaped slot widens behind the gap, so particles that enter pass through instead of wedging. | Cylindrical holes trap elongated, fibrous and platy solids, and blinding builds from the hole wall inward. |
| Pressure drop | Lower clean pressure drop at an equal slot size, and the rise as it loads is slower. | Higher clean pressure drop, rising quickly once a fraction of the holes blind over. |
| Slot tolerance | Continuous slot held to ±0.05 mm along the full length, with no ligament variation. | Hole size is fixed by punch tooling; accuracy depends on tool wear and plate thickness. |
| Cleaning and backwash | Backflush releases solids cleanly off the smooth V profile with little mechanical work. | Solids lodge in the straight hole wall and usually need brushing or high-pressure jetting. |
| Structural strength | Profile wire welded to support rods resists differential-pressure spikes without deformation. | Thin plate can deform or tear at the perforation pattern when differential pressure spikes. |
