Up to 33% More Capacity in Big Bags: Vibration Tables Optimise Recycling Logistics
A technologically leading company in plastics recycling processes lightweight packaging waste from the dual system into high-quality regranulates. After shredding, sorting and processing, the plastic flakes are temporarily stored in big bags prior to extrusion.
In this context, a logistical and safety-relevant problem became apparent: the big bags could not be filled evenly.
- Uneven filling of the big bags with a conical cavity
- Unstable storage and risk of tipping during internal transport
- Insufficient utilisation of container volume (only approx. 600 kg per big bag instead of 800 kg)
- Increased logistical effort due to additional containers and transport operations
Accompanied by technical consulting and process design directly on site, a total of twelve VTF series vibration tables from NetterVibration are now used for the uniform compaction of the plastic flakes. During the filling process, the tables transmit targeted vibrations to the big bag, allowing the material to settle homogeneously and reliably close existing voids. In this way, the plastic regrind is deliberately compacted in the big bag prior to extrusion and the shape of the container is stabilised. The vibration amplitude can be adapted to suit the regrind material. The vibration tables were integrated smoothly into the existing 24/7 recycling process.
- Up to 33% higher filling volume (from approx. 600 kg to over 800 kg per big bag)
- Reduced transport and storage costs due to higher utilisation
- Significantly more stable storage and reduced risk of tipping and safety hazards
- Improved occupational safety during storage and transport
- Fewer transports and lower CO₂ emissions as well as logistics costs: every fifth in-house transport run is eliminated!
