Density separator for recycling applications
Efficiently separate light and heavy materials with minimal density differences using this compact solution, designed to seamlessly integrate into existing sorting lines, enhancing your recycling processes with low energy consumption and variable settings for diverse material compositions.

The Lubo Vibro-Air Sort from Bollegraaf is a compact density separator engineered to tackle the complexities of sorting materials with minimal density variations. By employing a combination of laminar airflow and ballistic effects, it efficiently separates light and heavy components within varied waste streams, such as plastic waste, municipal solid waste, and construction debris. The equipment integrates seamlessly into both new and existing sorting lines, thanks to its space-saving design and flexible installation options.
The Vibro-Air Sort features a vibrating conveyor with adjustable angle settings, linked to a blast nozzle with variable configurations, allowing for precise control over material separation. Its dual vibration motors ensure stable and reliable operation. The equipment is particularly effective in recycling contexts, producing valuable end-products like recycled plastic pellets and refuse-derived fuel.
With low energy consumption compared to conventional methods, the Vibro-Air Sort offers favorable energy costs relative to the added value of recovered materials. Designed for continuous automated operation, it adapts to changes in material composition, maintaining efficiency and effectiveness across recycling, waste management, and demolition industries.
