The
Task
There is a growing need to classify manufactured sand, sand and gravel, waste materials, raw materials, semi-finished products, and finished products more effectively. Conventional vibrating screens and trommel screens are very limited when screening materials that cause a build-up on the screen, which results in clogging or blinding of the screen openings. The
bivi-TEC® was developed to screen even the most demanding materials.
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

The
biviTEC® Solution
Developed to screen even the
most problematic materials, the bivi-TEC offers a superior screening
solution for Superpave sands, scrap materials, compost, incinerator ash
and others. 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
biviTEC® Operating Principle
To assure 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 principle. 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.

Testing
and Demonstration
To properly size the bivi-TEC® for each
individual application, the following factors must be considered: material type, feed
gradation, product specifications, moisture content, and required capacity.
AEI has portable bivi-TEC®
plants for testing at your site.

Screen
Mats
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.
INSTALLATION
The screen mats are placed into the cross members and
locked into place by driving in the rubber wedge strip.
DISMANTLING
The screen mats are released by driving down a corner
of the wedge strip, followed by an easy pull on the mat.
