Strudex Screen Panels: Precision Performance, Unshaken Stability

Strudex longitudinal tension screen panels use a tensioned perforated surface for material sizing and grading. The retained edges, aperture fields and supporting profile form one working assembly. The pictured configuration has elongated openings separated by solid bands. Selecting the complete surface allows the plant to address both particle passage and stable seating, with the material specification and mating geometry defined for the supplied configuration.

Technical Parameters

Stable seating preserves the selected screening geometry

Longitudinal tensioning applies the retaining action in the direction defined by the screen assembly. Its purpose is to draw the surface into its designed working condition on the supports. The aperture arrangement performs the separation, while retained seating controls unwanted movement of that surface. This makes tensioning relevant to product consistency as well as to the mechanical life of the component.

Choose the opening for the material being separated

An elongated aperture presents two dimensions and an orientation to the feed. A flat or long particle may approach it differently from a roughly equidimensional one. The required grading therefore belongs beside the aperture drawing. Neither a photograph of the open pattern nor a single nominal dimension establishes a sharp separation curve. The panel should be evaluated as the installed geometry encountering a representative distribution of particle sizes and shapes.

• Control of the undersize: define which material is acceptable in the passing fraction, including the treatment of elongated particles. This establishes the product objective before a more open or differently oriented pattern is considered.
• Recovery from the oversize: identify acceptable undersize that remains on the deck. Blockage, bed coverage and limited opportunity to reach an opening can contribute to carryover. They should be distinguished from a hole that is simply unsuitable for the intended separation.
• Useful open area: include solid bands, margins, attachment regions and underlying obstructions in the review. A large visible field of apertures does not establish how much of that area is exposed and available to pass material during operation.
• Retention during work: preserve the intended position and support contact. Movement can change the local material path and introduce wear at contact points, even where the nominal opening pattern remains appropriate.

Separate three process decisions

The selected material requirement belongs with the agreed component geometry. Surface response, abrasive exposure, impact and the process environment should inform that selection. Keep the material reference and relevant acceptance properties on the same specification as the panel section and openings. This connects material behavior to an installable component and makes later replacements reproducible for the intended duty.

Use process observations to choose the next action

1. If coarse particles enter the undersize unexpectedly, distinguish passage through the selected openings from enlarged apertures, tears or joint bypass. Each mechanism changes a different part of the component or assembly.
2. If useful undersize remains in the oversize, inspect blocked area, bed distribution and the relation of openings to supports. Increasing the aperture is a process change and should be assessed against the required product.
3. If flapping or recurring support-contact damage accompanies the grading issue, review seating and the tensioning assembly before compensating with another opening. A configuration cannot be fairly assessed while its intended retaining condition is absent.

The practical payoff is a screening surface whose process geometry and mechanical condition can be controlled together. A panel can remain visually present after wear changes its openings, or retain the correct openings while an edge connection becomes unsuitable. Reviewing those states separately supports a focused replacement scope and a clearer choice of the next configuration.

Provide the panel layout, aperture dimensions and orientation, longitudinal retaining interface and support drawing with the selected material requirements and grading objective. Include representative feed conditions and the reason for replacement. These inputs define the complete working configuration and the dimensions and properties that need to be verified for the order.

Product FAQ

What does longitudinal tensioning mean for the screen panel?

It means the screening cloth is drawn taut along the longitudinal tensioning direction defined by the assembly. Confirm that direction on the drawing and distinguish it from material flow. The retaining connection and supporting profile must correspond to the panel’s intended installed condition.

Does the nominal opening alone establish the final product size?

The achieved separation also depends on particle shape, near-size content, moisture, bed coverage and screen conditions. Specify the required product grading alongside the opening. Representative checks of feed, undersize and oversize help establish whether an installed configuration meets that requirement.

Why might a newly fitted panel still flap or move?

Inspect support condition, retaining engagement and the applied tensioning procedure before changing the aperture. Worn contact profiles, incomplete seating or an unsuitable connection can allow movement. Compare the installed arrangement with its drawing and retain observations of where movement or recurring damage begins.

What should be controlled when ordering a repeat panel?

Keep the approved panel drawing, material reference, aperture pattern, longitudinal tensioning interface and support layout together. Identify its screen position and product duty. This preserves the accepted configuration and avoids replacing it with a superficially similar panel that changes either the connection or the required separation.
