Curved wedge wire sieve bend screens provide a continuous-slot surface for dewatering and solid–liquid separation. Radius, arc angle, working width, slot direction and supports are matched to the feed arrangement.
Wedge wire screensShare a drawing, reference sample or application requirements to discuss the configuration.
The panel curvature and working width fit the feed path and machine supports.
| Parameter | Specification | Notes |
|---|---|---|
| Screen form | Curved continuous-slot wedge wire panel | Working face defined by radius and included angle. |
| Fine-slot series | 0.05 / 0.075 / 0.10 / 0.15 mm | Discrete fine-slot configurations. |
| Curvature | Radius, included angle and effective arc | All dimensions refer to the working face. |
| Working width | Clear screening width between side boundaries | Record overall width separately. |
| Slot direction | Across material travel | Mark the feed direction on the panel drawing. |
| Back support | Curved support members and mounting seats | Keep the drainage path open. |
| Metal grades | 304 / 316L | Specify wires, supports and frame. |
| Inspection | Slot, radius, edge fit and support positions | Measure the finished curved assembly. |
| Minimum working-face slot | 0.025 mm | Fine-slot curved-screen series; slot measured on the finished working face. Common discrete slots remain 0.05 / 0.075 / 0.10 / 0.15 mm. |
Materials: 304 / 316L stainless steel; specify profile wires, supports and frame separately.
Feed enters tangentially and travels down the curved working face. Liquid passes through slots running across the travel direction while retained solids continue along the surface. The component is the screening panel; the feed box, collection chamber and supporting machine define its installation.
Specify the working-face radius, included angle and effective arc length together. The drawing separates overall width from the unobstructed screening width. End lips, side plates and fixing points locate the panel without covering the intended active surface.
Profile wires form the narrow working-face openings and widen the passages behind the face. Fine-slot configurations include 0.05, 0.075, 0.10 and 0.15 mm openings. Slot direction, wire face width and support spacing are recorded as separate construction parameters.
The inlet edge meets the feed box at the specified position and tangent. Supports follow the curved geometry on the back of the panel and connect to the machine seats. The arrangement keeps the liquid collection path open and provides access to both sides for cleaning.
Check slot width at several positions, radius, arc geometry, edge fit and support locations. The replacement drawing includes the machine seats and the feed edge rather than only a flat length and width. Handle the panel at its supports to preserve the working surface and curvature.
Sieve bend screen and DSM screen are established commercial names for a curved static screen. Kaifil supplies the wedge-wire panel that fits the screen assembly. Its replacement drawing pairs working-face radius, included arc angle, effective arc length and clear screening width with slot width and wire orientation. Match the inlet edge and feed tangent to the feed box, then define side boundaries, end lips, back supports and mounting-seat positions. The feed box, housing and collection chamber are separate assembly components; the panel drawing defines the supplied screening surface and its installation interfaces.
| Feature | Screening role | Drawing definition | Acceptance check |
|---|---|---|---|
| Working face | Drains liquid across continuous slots | Slot, profile and feed direction | Slots across the finished face |
| Curvature | Controls the material travel path | Radius, angle and effective arc | Curve and inlet tangent |
| Side and end edges | Locate the active screening area | Clear width, lips and mating edges | Seat fit and free area |
| Back supports | Transfer panel loads to the machine | Support section and seat positions | Alignment and drainage clearance |
| Slot s (mm) | Wire face b (mm) | Pitch p = s + b (mm) | Calculated face open area (%) |
|---|---|---|---|
| 0.05 | 1.2 | 1.25 | 4.0 |
| 0.075 | 1.2 | 1.275 | 5.9 |
| 0.10 | 1.2 | 1.30 | 7.7 |
| 0.15 | 1.2 | 1.35 | 11.1 |
The four rows use a 1.2 mm wire face and calculate p = s + b and face open area = 100 × s / (s + b), rounded to one decimal place. This is the repeating slot-pattern geometry. Frame overlap, end closures and support footprints are accounted for in the exposed assembly area; hydraulic flow is specified with the process conditions.
| Supply item | Order basis |
|---|---|
| Production lead time | 2–3 weeks after order and drawing confirmation. |
| Trial orders | Small trial quantities for fit and process evaluation. |
| Regular production orders | 50 pieces or US$3,000 per order. |
| Quotation basis | Material, finished dimensions, filter construction, connections and quantity. |
Curved slot panels drain liquid along a controlled feed path in screening equipment.
The screen separates a draining liquid fraction while retained material travels along the curved face.
The panel matches the feed box and liquid collection layout for the specified process slurry.
Include these details when discussing your requirements.
Its working face has a defined radius and arc angle, with feed introduced along the inlet tangent.
The working slots run across material travel. The drawing marks the feed direction and the active face.
Working radius, included angle, effective arc, clear width, edges, support seats and feed-interface position.
The specification also defines feed properties, profile geometry, inlet arrangement, supports and the exposed screening area.
Check slots, curvature, edge fit, support locations and clearance for drainage and cleaning.
