A southeast C&D Recycling facility has recently chosen to replace their existing trommel screens with a BIVITEC® screen to remove ½” minus fines from -2″ fines. The Trommel which was previously used to perform this function was worn out after only 4 yrs of operation. The BIVITEC® provides 3 times the effective screening area in a smaller footprint as compared to the previous Trommel.
Of particular concern to the customer was the plugging during high moisture conditions presented by their outdoor location in the south east. The BIVITEC®’s non-blinding design keeps the panels open in all conditions providing year round efficient screening. After installation, it was discovered that the BIVITEC® was too efficient at ½”! Although the trommel was sized at ½”, blinding of the Trommel resulted in a size reduction to near ¼” with significant carry over.
Reducing the BIVITEC® mesh size to ¼” provided efficient screening while maintaining product continuity. Even at this smaller opening, the BIVITEC® decks remain clear even in wet conditions. The flexibility and easy change nature of the deck allows the customer to mix panel configurations in a given deck to fine tune product specifications and adjust to material feed conditions.
The complete solution to the customer’s screening problem was provided in partnership with General Kinematics. General Kinematics is a BIVITEC® partner and specializes in solutions incorporating the BIVITEC® screen, manufactured by AEI.
