Hi Tony,
The screen is the first component to deform when:
Wet or stringy material packs behind it
There’s uneven pressure on one side
The screen is pulled downward while still under load
The retaining system is slightly misaligned
Before bending anything
Before forcing the screen back into position, run through this quick checklist to ensure the problem isn’t elsewhere:
1. Check the cradle / carrier / screen frame for packed material
Sometimes debris hides in the frame lip—not visible from the top.
2. Confirm the screen drops fully into its normal seating position
If it’s sitting 1–2 mm off, the pin hole won’t align.
3. Check both sides of the screen for symmetry
If one side is lower or twisted, that strongly indicates bending.
4. Check the pin itself
If the pin is slightly bent or burred, it can also cause misalignment even if the screen is fine.
carefully, and only enough to refit it.
Screens on most commercial shredders are mild- or abrasion-resistant steel but still somewhat flexible. Operators frequently "tweak" them back into shape.
Avoid bending if:
The screen is cracked or warped severely.
Do a slow-speed test after reinstalling to make sure the rotor doesn’t brush the screen.
Cheers
Max.
