CUSTOM INDUSTRIAL SCREEN COMPONENTS
Sieve Bend Screens
A sieve bend screen is a curved wedge wire surface used for solid-liquid separation. Feed travels over the curved screening face; part of the liquid and sufficiently small material passes through the slots while retained material continues over the surface.

Where this screen fits
Sieve bends are used in dewatering and recovery duties, including mineral processing and food-process separation. Selection needs the feed conditions as well as the screen geometry. Solids loading, particle shape and the way feed reaches the surface influence the result.
Specification checklist
Use this checklist for an enquiry or drawing review. Dimensions and slot openings are specified for the project; the table is not a stock-size or guaranteed-capability range.
| Parameter | Information to provide | Why it matters |
|---|---|---|
| Curved geometry | Screen width, radius and included arc angle | State whether length means arc length or a straight-line measurement. |
| Slot and surface | Nominal slot, tolerance and profile wire orientation | Mark feed direction and the working face on the drawing. |
| Feed conditions | Flow rate, solids concentration and particle description | Include how feed is distributed across the width. |
| Mounting | Side plates, edge bars, frame and attachment points | Show the screen seat and any adjustment or removal space. |
| Service and cleaning | Medium, temperature, abrasion and cleaning method | Separate expected operating conditions from occasional extremes. |
Agree the acceptance points
Identify the characteristics that decide whether the screen is acceptable for your equipment:
- Radius, width, arc geometry and frame fit.
- Slot opening, wire orientation and feed direction.
- Side-plate positions and mounting interfaces.
Ask for the required inspection records, sampling basis and material documentation in the quotation. Availability and scope need to be confirmed for the order. Review the documentation checklist.
Ordering and replacement details
Send the drawing revision, quantity and delivery destination. For a replacement, include installation photos, the equipment reference and any wear or fit problems.
Material grade, tolerances, minimum order quantity, packing, lead time and delivery terms are agreed in the quotation. A similar-looking product photograph is not a compatibility confirmation.
Questions about sieve bend screens
Are slot size and separation cut size the same?
The physical slot opening is a screen dimension. Actual separation depends on the feed, particle shape, flow and screen arrangement. A slot value alone is not a guaranteed separation cut size.
What should I measure on a replacement sieve bend?
Record width, radius, included angle or arc length, slot opening, side-plate details and mounting positions. Mark the feed direction and photograph the working surface and support side.
