How to Install WS85 and Trellex LS Panels
The Core Principle
Compatibility comes before installation. Installation verification comes before performance evaluation. DEWATERING PANELS
WS85 and Trellex LS are different screening-media installation systems. They should not be treated as interchangeable simply because their panel dimensions appear similar.
Step 1: Identify the Existing System
WS85-style systems commonly use profiled panel edges and a compatible locking or knock-in bar that engages with supporting girders.
Trellex LS modules use modular mounting and rail arrangements with specified compression and end stops.
Confirm: screen manufacturer and machine model, existing screening-media system, panel or module dimensions, aperture size and shape, underside reinforcement and support-contact geometry, fixing profile and rail arrangement, deck layout, any previous modifications.
Step 2: Verify Mechanical Compatibility
Two panels can have similar external dimensions but different locking geometry. Their support contact, panel height, retaining features, and underside construction may also differ.
⚠️ Confirm mechanical compatibility before comparing price, hardness, aperture design, or expected wear life. A panel that does not fit correctly is not a suitable replacement, regardless of its material properties.
Step 3: Prepare the Deck
Stop and isolate the equipment. Follow lockout and safe-access procedures. Never adjust panels while the screen is operating.
Inspect the supporting structure: support girders and cross members, locking bars and rails, side plates and edge supports, end stops, areas where material has accumulated.
Check the deck layout: number and position of modules, side panels, rail components, edge pieces, staggered joints.
Why this matters: a new panel cannot compensate for a damaged rail, incorrectly positioned locking component, or unsuitable deck arrangement.
Step 4: Install Using the Correct Procedure
WS85-style workflow:
-
Verify girders and locking components match the approved layout
-
Position locking components correctly
-
Confirm panel orientation and profile
-
Install in the specified sequence
-
Ensure edges engage with retaining profile
-
Check ends align with deck reference points
-
Complete using approved tools and method
Trellex LS workflow:
-
Confirm rail type, module dimensions, deck arrangement
-
Inspect rails and retainers for damage or contamination
-
Position each module according to layout and orientation
-
Engage using the prescribed method
-
Verify seating and specified compression
-
Confirm end stops and retaining arrangements
-
Inspect for loose modules, gaps, misalignment
⚠️ Do not force a panel. Unexpected resistance indicates misalignment, contamination, damaged components, or compatibility problem. Stop and investigate.
Step 5: Verify Retention Before Restart
A visually complete deck is not necessarily a correctly installed deck.
Check: panel seating, module movement, alignment, edge and side protection, support contact, foreign objects.
For Trellex LS specifically: verify compression and end-stop arrangement.
Step 6: Commission and Monitor
Observe from designated safe locations for: abnormal noise, unexpected vibration, material accumulation, uneven feed distribution, drainage changes, material escaping through gaps, abnormal panel movement.
Evaluate more than throughput:
-
Required product size and separation quality
-
Dewatering performance
-
Stable material distribution
-
Blinding and pegging frequency
-
Panel wear patterns
-
Maintenance and replacement time
-
Downtime
-
Total screening-media cost per tonne processed
Failure Analysis
| Problem | Possible Cause | Recommended Solution |
|---|---|---|
| Panel movement | Incorrect fixing, worn locking components | Inspect mounting system and retainers |
| Panel does not engage | Misalignment, wrong orientation, contamination | Stop and investigate cause |
| Gaps between panels | Incorrect seating, damaged supports | Check support contact and alignment |
| Module movement (Trellex LS) | Insufficient compression, missing end stops | Verify compression and end-stop arrangement |
| Material escaping through gaps | Poor seating, incomplete engagement | Re-seat panels, check retention |
Case Study
Customer Type: Sand washing plant
Ore Type: Fine quartz sand with clay content
Operating Conditions: Continuous wet dewatering, abrasive slurry
Problem: Replacement WS85-style panels developed movement and edge damage within weeks. Operators suspected material quality.
Solution: Inspected the deck and found worn locking bars and accumulated material beneath panel seating areas. Replaced locking components, cleaned contact surfaces, reinstalled using specified procedure.
Result: Panel movement eliminated; edge damage resolved; service life returned to expected interval.
FAQ
Can WS85 and Trellex LS panels be used on the same deck?
Not automatically. Different mounting profiles, support arrangements, and retaining mechanisms. Confirm compatibility against actual deck and panel drawings.
What is the most important check before installation?
Panel dimensions, underside profile, fixing geometry, and mounting arrangement must match the deck. Support structure inspection is equally important.
Why check Trellex LS compression and end stops?
The system retains modules in position. Inadequate retention allows unwanted movement.
Should a panel be forced if it does not fit?
No. Unexpected resistance indicates a problem. Stop and identify the cause.
How do I know if installation improved performance?
Record operating conditions before and after. Compare drainage, product consistency, blinding frequency, wear patterns, operating hours, maintenance requirements under comparable conditions.
What causes uneven seating?
Trapped material, worn support bar, incorrect orientation, or mismatched profile.
Why is a visually complete deck not necessarily correct?
Panels can appear seated but fail to engage retaining geometry. Verification requires checking seating, retention, alignment, and support contact.
What if material escapes through gaps?
Stop and inspect panel seating, edge protection, and retaining components. Incomplete engagement requires re-seating.
What metrics should I monitor?
Product size, separation quality, dewatering performance, feed stability, blinding and pegging frequency, wear patterns, maintenance time, downtime, cost per tonne.
What is the most common installation mistake?
Transferring a procedure from one system to another. Use the method approved for the specific system.
Conclusion
Installing WS85 and Trellex LS compatible panels correctly requires more than placing modules on a deck. Identify the system, confirm compatibility, inspect supports, fit using the correct procedure, and verify retention before returning to service.
Compatibility comes before installation. Installation verification comes before performance evaluation.
A systematic approach prevents avoidable fitting problems and creates a reliable basis for evaluating dewatering performance, panel wear, and maintenance costs.
