When it comes to material screening, not all vibrating screens are created equal. Standard flat-deck screens can perform well in many situations, but they often struggle with damp aggregates, sticky clays, stalky compost, leafy biomass, or matted substances from waste streams, becoming a critical production bottleneck.
Meanwhile, the BIVITEC® banana design has a unique curved deck that’s paired with innovative flip-flow technology. It’s engineered to maximize efficiency, improve stratification, and handle the toughest materials with ease.
Understanding Standard Vibrating Screens
These screens have a relatively simple design: a flat, horizontal deck vibrates at high speeds to separate materials based on size. As material flows across the deck – smaller particles fall through the openings, while larger particles continue to the discharge end.
These screens have a compact design and offer a controlled material flow, operating on a principle of precision conveyance. Their most common and effective application is as a finishing screen in aggregate and mining operations. After material has been crushed and washed, the horizontal screen provides the high accuracy needed to create precise final product specifications for concrete, asphalt, and other high-value applications.
However, standard vibrating screens may struggle with blinding and plugging as well as stratification efficiency, as the flat deck doesn’t always encourage material to spread evenly or separate quickly.
Compare inclined versus horizontal screens.
The BIVITEC Screen’s Banana Design
Unlike flat horizontal screens, the banana design features a steeper angle at the feed end that gradually lessens toward the discharge. This geometry allows material to move more efficiently across the deck while maintaining a consistent bed-depth from start to finish.
By keeping the bed-depth even, the Banana BIVITEC® maximizes tonnage capacity without sacrificing accuracy. Combined with the dual-vibratory, flip-flow system and flexible polyurethane screen mats of the BIVITEC® screen — engineered to eliminate blinding and clogging — the banana design offers greater efficiency, reduced downtime, and higher throughput compared to standard screens.
The BIVITEC® is the definitive solution for applications defined by difficult, variable, and high-moisture feed materials.
- Recycling (C&D, MSW, ASR): The BIVITEC® is uniquely capable of screening materials that would instantly paralyze a horizontal screen, such as removing high-moisture fines from construction and demolition (C&D) waste, classifying auto shredder residue (ASR) and its associated fluff, and handling sticky incinerator ash.
- Compost and organics: The BIVITEC® is the ideal technology for screening compost, wood waste, peat moss, and other organic materials that are inherently fibrous, leafy, and tend to mat together on a screen deck. The high-G acceleration actively breaks up these clumps, ensuring a consistent and high-quality final product.
- Difficult minerals and aggregates: In the aggregate and mining sectors, the BIVITEC® excels where the raw feed is contaminated with high percentages of silt, mud, and clay. It is a leading solution for producing manufactured sand and agricultural lime, where fine particles and moisture are inherent to the process.
- High-moisture materials: The BIVITEC® is the definitive solution for any application where high or variable moisture content is a persistent challenge. Its flip-flow action eliminates the need for expensive and energy-intensive solutions, like heated decks or less effective ball decks, providing reliable performance in all weather conditions.
