bivi-TEC - Screen
Bivi-TEC allows the screening of the most difficult materials without plugging or blinding. The unique action of the deck provides high acceleration forces on the material to keep the deck free and clear.
The bivi-TEC proves to be the best machine for screening:
- Manufactured sands, chips and aglime
- High-moisture materials combined with silt, mud, and clay.
- Incinerator ash, trash, waste coal, clay, sand, and slag.
- Compost, leafy materials, wood waste, and peat moss.
- Auto shredder fluff, shredded tires, and roofing shingles
Developed to screen even the most problematic materials, the bivi-TEC’s unique dual-vibratory screening process eliminates clogging and blinding of the screen openings to save downtime and increase productivity.
To ensure the most effective screening, high-acceleration forces must be transferred to the feed material. The bivi-TEC Screen achieves these high forces by dynamically tensioning and relaxing the flexible screen mats using a dual vibration principal. Enhanced by resonance, one drive can produce two vibration movements. The screen box is accelerated approximately 2g’s while the screen mats can receive up to 50g’s.
Applications once judged impossible, can now be accomplished with the bivi-TEC screen.

- Fine screening of moist material
- Eliminates blinding and plugging
- High capacity – Large effective screening area
- Long Life Polyurethane screen mats
- Rugged Construction, Low maintenance
- Highly flexible for varying material conditions
- Low energy usage
To properly size the bivi-TEC for each individual application, the following factors must be considered: material type, moisture content, feed gradation, product specifications and capacity
AEI conducts all testing on customer site to ensure real world material and operating conditions. Contact us for a test at your location.
The bivi-TEC Screens are designed for screen cuts of 35 mesh to 2 inches. The boltless attachment of polyurethane mats guarantees effective screening, rapid changing of screen mat, and elimination of clogging. The 13' wide mats offer greater flexibility in tuning the screen to achieve the final product-resulting in a lower replacement cost. Approximately 15 minutes is needed to change 50 square feet of screen surface.
The screen mats are placed into the cross members and locked into place by driving in the rubber wedge strip.
The screen mats are released by driving down a corner of the wedge strip, followed by an easy pull on the mat.
The bivi-TEC is available in sizes ranging from 800mm X 3M (3' x 10') to 2400 mm x 8M (8' x 27').
The following options are also available:
- single deck
- double deck
- rigid scalping deck
- portable/stationary units
- custom sized to fit your installation
Each bivi-TEC screen is built to fit the customer's specifications. AEI can also engineer and manufacture a complete material processing system including: conveyors, stackers, supports, chutes, etc.
