To install WS85 and Trellex LS compatible polyurethane dewatering panels successfully, first identify the existing screen deck system, verify mechanical compatibility, inspect the supporting structure, follow the correct installation procedure, and complete a thorough pre-start inspection. WS85 and Trellex LS are different screening-media installation systems — they should not be treated as interchangeable simply because their panel dimensions appear similar.
Compatibility comes before installation; installation verification comes before performance evaluation.
WS85-style systems use profiled locking components and supporting girders.
Trellex LS modules use modular mounting and rail arrangements with compression and end stops.
Similar external dimensions do not guarantee interchangeable locking geometry.
Trapped material beneath panels creates gaps and interferes with support contact.
A visually complete deck is not necessarily a correctly installed deck.
Maximum performance means meeting process objectives, not maximum throughput.
| Item | Description |
|---|---|
| Function | Install polyurethane dewatering panels for consistent screening performance |
| Systems | WS85-style (profiled edges, locking bars) vs Trellex LS (modular rails, compression) |
| Critical Check | Mechanical compatibility before installation |
| Verification | Seating, retention, alignment, end stops, support contact |
| Performance Basis | Process objectives, not throughput alone |
WS85-style and Trellex LS-compatible polyurethane dewatering panels are modular screening media installed on vibrating screen decks for wet screening applications. They differ in installation structure: WS85-style systems commonly use profiled panel edges and locking bars engaging with supporting girders; Trellex LS modules use modular mounting and rail arrangements with specified compression and end stops.
Panels separate solids from water while providing a replaceable screening surface. Correct installation ensures panels remain securely seated and loads transfer properly into the deck.
Incorrect installation — poor seating, incompatible fixing components, damaged supports, or inadequate retention — creates operational problems including uneven material flow, abnormal wear, leakage at unintended gaps, and mechanical damage.
Correct seating. Panels engage with specified support and fixing components.
Proper load transfer. Forces distribute into the deck as designed.
Consistent screening surface. No local discontinuities that affect material flow.
Reliable retention. Modules stay in intended positions during operation.
Meaningful performance evaluation. Baseline data allows comparison with previous configuration.
Polyurethane dewatering panels are applied in sand washing, aggregate processing, mineral beneficiation, tailings treatment, and other wet screening applications.
Dewatering sits downstream of SCREENING and upstream of FILTRATION and TAILING management.

| Panel edge | Profiled | Module-specific |
| Fixing method | Locking or knock-in bar | Modular rail arrangement |
| Support | Supporting girders | Corresponding LS rails |
| Retention | Locking components | Compression and end stops |
| Installation procedure | Not transferable | Not transferable |

| Application | Key Installation Concern | Verification Focus |
|---|---|---|
| Sand washing | Correct seating, drainage | Panel alignment, support contact |
| Aggregate processing | Impact resistance, retention | End stops, locking components |
| Mineral beneficiation | Aperture accuracy | Panel orientation, compression |
| Tailings treatment | Fine retention, drainage | Seating, edge protection |
| Coal dewatering | Blinding control, retention | Module movement, gaps |
| Industry | Typical Feed | Key Installation Risk | Prevention Focus |
|---|---|---|---|
| Sand & Gravel | Fine sand, clay | Poor seating, gaps | Deck inspection, compatibility |
| Coal | Wet fines | Module movement | Compression, end stops |
| Iron Ore | Fine slurry | Load transfer issues | Support contact, alignment |
| Gold | Oxide slurry | Aperture misalignment | Panel orientation |
| Copper | Sulphide slurry | Retention failure | Locking components |
| Aggregates | Crushed stone | Impact damage | Correct procedure, no forcing |
| Tailings | Fine tailings | Drainage inconsistency | Seating, edge protection |
| Phosphate | Sedimentary slurry | Moisture, abrasion | Correct procedure, verification |
Six steps determine successful installation:
Identify the existing system — WS85-style or Trellex LS. Confirm screen manufacturer and machine model.
Verify compatibility — panel dimensions, aperture, underside profile, fixing geometry, rail arrangement, deck layout.
Prepare the deck — isolate equipment, inspect supports, remove accumulated material, correct defects.
Install using the correct procedure — system-specific method, approved tools, correct sequence.
Verify retention — seating, module movement, alignment, edge protection, support contact, foreign objects.
Commission and monitor — observe for abnormal conditions, record baseline, evaluate against process objectives.
Required information: screen manufacturer and model, existing screening-media system, panel or module length, width, thickness, aperture size and shape, underside reinforcement and support-contact geometry, fixing profile, retaining components, rail arrangement, deck layout including side panels and edge conditions, any previous modifications.
Drawings needed: original drawings or sample from existing installation, photographs of panel top, underside, edges, and mounting components, photographs of supporting rails and deck arrangement.
Material selection: request PU formulation and hardness data, panel thickness, aperture tolerance specification.
