Gamma Meccanica - Model Tandem lines - Plastic Recycling System
The TANDEM technology applied to the recycling of heavily printed, contaminated and high humidity plastic materials guarantees the excellent quality of the granule with a notable energy savings in comparison with conventional recycling systems that foresee the re-extrusion of the material. The plant is composed of a COMPAC unit and two extruders arranged in succession. The short, non-vented primary extruder and the larger diameter secondary extruder allow for a reduction of the cutting forces (“shear rate”) and stress less the melted material. Between the first and second extruders there is a high performance degassing chamber. Here the surface of material exposed to vacuum is 10 times greater than the exposure of a normal extruder, guaranteeing the extraction of large quantities of gas and contaminants. Another important benefit of the Tandem line is the possibility to have double filtration.
