The customer had recently purchased and commissioned two new 8×24 4-deck Deister(R) screeners, configured with 1×2 rubber pin and leg panels from a well-known urethane and rubber modular screening manufacturer. This configuration only produced 40-50% of their anticipated hourly tonnage, which would have resulted in significant production shortfalls and lost sales revenue.
After investigation, Buffalo TechSquad™ determined that these pin and leg panels caused the production constraint by reducing open area and causing the material to peg in the screen openings.The Buffalo TechSquad™ determined that our Modular PFX Hybrid panels would be ideal for increasing the customer’s production. The customer installed Buffalo Modular PFX Hybrid panels on the second half of the deck, leaving the rubber panels on the first half to absorb the impact but still maintain some throughput. Combining lower open area impact-resistant rubber panels and the self-cleaning Buffalo Modular PFX Hybrid panels was the perfect solution for the action of the screens, allowing for greater production and reduced pegging.
Buffalo Modular PFX Hybrid panels increased the customer’s production by 40% compared to a full deck of the competitor’s rubber panels. The Buffalo TechSquad™ solution eliminated and removed the most significant bottleneck in the plant and helped allow the rest of the equipment to run at much greater efficiencies. As a result, the customer decided to convert both screeners’ complete machines from flat deck modular panels to a crowned deck system utilizing Buffalo’ PFX self-cleaning hooked screen panels. This change enhanced the system’s productivity and reduced the overall screen costs. Since the first conversion was very successful, the customer used Buffalo help to convert six additional screeners in the same pit, increasing their production volume.
