AET's densifying, heavy duty reclaim extruders are designed especially for the reclamation of low bulk density scrap. This line of extruders features two different diameter screws, a large one, and a smaller one that are keyed together for easy removal. The smaller screw can be removed from the front of the machine, similar to the way a standard extruder feed screw can. By combining the greater feed capacity of the larger feed screw with the economy of the smaller one, AET's design concept provides an ideal system for processing often hard-to-handle low bulk density scrap feed forms effectively and economically. The scrap is fed directly through AET's "over sized" feed section. The scrap then goes into the large, first stage, densifying screw after which it is compressed and conveyed to the small diameter preplastisizing screw. This produces the ideal compression ratio to melt the material for delivery to the automatic screen changer and pelletizer.

• Effectively processes low bulk density scrap such as film, foam fiber, as well as hard-to-feed virgin polymers.
• Eliminates the need for screw (crammer) or ram feeder
• Upgrades product quality
• Minimizes or eliminates pre-processing of scrap processes material with bulk densities down to 1/3 lb. per cubic foot (.1 kg. per cubic meter) easily
• Higher output, up to 100% or more when compared with conventional reclamation systems
