Drying and Decoating System

Two systems are available for continuous Drying and/or Decoating of aluminium Chips and dirty Scraps (UBC, Profiles, Litho, ...)

  • IDEX® System (Patented Technology), specially designed for drying or decoating within a range from 500 kg/hr to 15 ton/hr.
  • ECO-Kiln® System (Patented Technology), compact design, limited for Chips drying with water coolants, up to 300 kg/hr.

IDEX® System

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.

ECO-Kiln® System

It is compact system where the postcombustion and drying chamber are in the same rotary kiln.

Benefits of Drying/Decoating

Economical arguments

  • 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.

Enviromental arguments

  • Reduce emissions, waste gas controls.
  • Pollution control.
  • Reduce landfil disposal.
