AEI bivi-TEC

bivi-TEC Screen

The bivi-TEC’s unique dual-vibratory screening process eliminates clogging and blinding of the screen openings to save downtime and increase productivity. Dual vibration from a single drive is the unique feature of the bivi-TEC® Screen. Two weights, vibrating at the same frequency, move relative to each other which tensions and relaxes the screen mats. The linear momentum of both vibrating movements is adjustable, resulting in open screen surfaces and optimal screening performance.

The bivi-TEC® was developed to screen even the most demanding materials.

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.

Approximately 15 minutes is needed to change 50 square feet of screen surface.
