Chopper-Feeder-Extruder combination E-GRAN

Technology

Plastic film and film edge trim are chopped directly in the extruder feed section. The conically shaped conveying area of the screw compresses the material as it enters the extruder.

In the extruder, the material is brought to a uniform melt temperature and subsequently pelletized.

The feed section (where the material is chopped), conveying area and the extruder all lie along a single shaft. The resulting design requires only one energy-efficient drive.

All the components are positioned in close proximity to prevent oxidation of the material and to make optimal use of heat from the chopping process.

All models in the E:GRAN series feature this patented chopper/feeder/extruder combination.

One-Step Technology

In a single step process, the film edge trim is chopped directly in the extruder feed section and fed into the extruder.

High Performance for a small space requirement

With its compact design, the system can be installed in areas of limited space and its versatility also allows it to be integrated at a later time in the main process.

One-Button Automatic ON/OFF Controll

Convenient startup and shutdown
Restart after unplanned shutdown in less than two minutes with full extruder
The control system provides for smooth start-up of

For automatic inline Production

Automatic response to differences in quantity when processing edge trim ensures consistent pellet quality
