An aggregate operation experienced significant screen blinding during the winter months, when high moisture and sticky clay caused material to adhere to the screen surface. As apertures are plugged, the open area decreases, reducing throughput and creating inconsistent production. The operation needed a screening solution that could keep decks cleaner despite increased seasonal moisture.
Buffalo first recommended PFX™ self-cleaning screens to improve cleaning action and maintain higher throughput. Since the operation had recently replaced its media, they preferred a temporary option before committing to a full changeover.
As an interim solution, Buffalo suggested installing declogging chains and provided guidance on proper setup.
After further on-site evaluation, it became clear that a more permanent fix would be beneficial. Because the material coming off the VSI crusher was highly cubical, Buffalo recommended upgrading to the PFX™-L, which is specifically designed to deliver stronger cleaning action for sharp, angular stone applications.
The operation installed the declogging chains and immediately saw reduced blinding under high-moisture conditions. Building on this improvement, they purchased PFX™-L screens, which are now onsite and scheduled for installation.
Once installed, PFX™-L is expected to deliver consistent cleaning performance, improved winter uptime, and more reliable throughput, offering a durable, long-term solution to seasonal screening challenges.
