Effective Fine Screening For the Most Difficult Materials

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.

Benefits of the BIVI-TEC®

The BIVI-TEC® Solution

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.

bivi-TEC® Vibration DiagramTo 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

BIVI-TEC® proves to be the best solution for screening:

  • Manufactured sands, chips, ag lime
  • 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, roofing shingles, C+D waste, RDF
