The IDEX® is designed to give maximum flexibility together with minimum fuel consumption and emissions. It is an indirectly fired rotary kiln for thermal delacquering / drying that removes volatile organic compounds (VOC), such as water coolants, paints, oils, … from the surface of crushed aluminium materials.
The system is completed with a postcombustion chamber for the incineration of the hazardous gases generated during the drying/decoating process.
Hot exhausted gases are recirculated to the rotary kiln to eliminate the VOC, without any additional energy supply and so reducing the overall thermal consumption to the minimum.
Final exhausted gases to the atmosphere are innert and comply with the most strict EU enviromental regulations.
It is compact system where the postcombustion and drying chamber are in the same rotary kiln.
Benefits of Drying/Decoating
- Increase metal yield during melting.
- Safer melting process, no water.
- Low Salt / flux usage on melting.
- Increase melting rate.
- Increase of scrap value.
- Firing VOC pollutants reduce overall fuel consumption.
- Reduce emissions, waste gas controls.
- Pollution control.
- Reduce landfil disposal.
