An aggregate producer processing 3" minus material from a grinder was experiencing significant screen blinding on their woven wire media. Material was clogging the apertures, reducing open area and lowering overall throughput.
Beyond the throughput loss, the blinding issue increased carryover, sending excessive fines back into the crusher and adding unnecessary load to downstream equipment. The operation needed a screening solution that could relieve blinding while maintaining durability.
Buffalo recommended PFX™ self-cleaning screens for the top deck, and the TechSquad™ engineering team conducted a site visit to confirm the appropriate PFX™ configuration. After assessing the full setup, the team also identified an opportunity to improve performance on the bottom deck.
The customer chose to start with the top deck only, preferring not to implement multiple changes at once to avoid impacting their overall process. The PFX™ screens have performed exceptionally well since installation, and the operation is now evaluating a bottom-deck conversion in the near future.
Buffalo originally supplied woven wire screens to meet the plant’s immediate needs. After positive performance and durability feedback, the customer shared ongoing blinding challenges with another screener during a follow-up visit—opening the door to a PFX™ recommendation.
Since installing PFX™, the customer has seen improved cleaning action, reduced blinding, and more consistent throughput. As a result, Buffalo has become their preferred screen supplier, and the operation is now ordering additional screens for inventory. This positions PFX™ as their go-to solution for reducing downtime and maintaining efficient production.
