Short Description

In waste management, sensor-based sorting systems are used for the sorting and analysis of waste streams and bulk materials. For this reason, a new experimental sensor-based sorting setup is installed for research purposes at the Chair of Waste Processing Technology and Waste Management (AVAW) at the Montanuniversitaet in Leoben. The experimental setup is also a compactly built, sensor-based analysis device that is optimized for use in universities. A grain size range between 5 and 150 mm can be achieved.

The experimental sensor-based sorting setup consists of the following components:
- Task unit and vibration conveyor
- Chute
- Emitters
- Visible spectroscopy (VIS), near-infrared (NIR) & induction sensor
- Compressed air valve bar
- Splitter

To carry out experiments, bulk materials are placed on the task unit, transported through the vibrating conveyor and separated. The material is transported to the chute, dismantled via the chute and is detected by the built-in sensors (VIS, NIR, induction). The classification of the individual objects enables the particles to be sorted using compressed air valves. The sorted bulk material is analyzed measured with an evaluation software.

There are various different areas in application of the experimental sensor-based sorting setup as part of university operations:
- Sample characterization and determination of the composition,
- Representation of a digital grain payment distribution,
- Discharge of contaminants,
- Enrichment of valuable substances,
- Sorting of bulk goods according to substance groups and
- Validation of sorting / separation results
- Simulation of sorting processes.
