| Counterflow Concept |
|
The IDEX® Decoating System
further advances the counterflow concept developed by
Gillespie + Powers, Inc. to unlimited levels of flexibility.
Careful control of
atmosphere, temperature, and flow through the kiln is key to successful
operation. An IDEX®
system built by Gillespie + Powers, Inc. and controlled by our Automation
department, can achieve unparallel control.
|
| Decoating Process |
|
Decoating removes decorative, protective, or other layers of
material on the surface of the aluminum with minimal effect on
the aluminum itself. Coatings are predominantly paint, plastic,
or paper, and largely organic.
|
| Aluminum Industry Applications |
IDEX® processes many
materials:
| Painted Siding |
6 Micron Foil |
| Used Litho |
Plastic Laminates |
| Window Frames |
Paper Laminates |
| Turnings/Swarf |
Epoxy Strip |
| Frag/Twitch |
Cap stock |

Notice the tube, this is the main part of the IDEX® system |
| Advances and Advantages |
- Captures Pollutants
- Increases Thermal Efficiency
- Reduced Size, Floor Space, Maintenance Make Operation
Economical
- Computerized Controls Increase Flexibility
- Afterburner Design Ensures Good Mixing
|
| Principal Components |
|
The system is based on a rotating counterflow
mixing design concept, complete with all the necessary hot gas
recirculating equipment, control systems, ducting and supporting
steelwork. Shredding equipment is also available.
