Sizing Screens
- Welded screens are guaranteed to last three times longer than woven screens because woven screens have crimps which weaken the wire and welded wire is much more abrasive resistant.
- Welded screens give up to 20% more throughput than any other media.
- Screen changeouts are reduced and are predictable.
- Wires can be clustered to protect support bars.
- A smaller piece of screen or “wearpad” can be welded on a screen in the feed area to strengthen the screen locally and to significantly increase wear life, while maintaining open area.
- Virtually any hole or slot size can be supplied.
- Welded screens are easier to install as they are arched to fit the deck
- Customers have stated that plugging/blinding problems were eliminated with welded screens.
- The hole size is always maintained.
- Welded screens are lighter than woven, plate or synthetics.
