Function
Simplified feeding process with large single portions
… and consequently reduced feeding labour (operator cost) is another positive result of the new design.
The enlarged cutter compactor drum allows the feeding of the system with larger single portions of plastic waste without disturbing the temperature homogenity in the drum. The result is a more steady and robust overall behaviour of the plant at stable, high output rates independent from the feeding personnel.
This, in combination with the optional T-DD* cutter compactor execution (see separate folder), plus the advanced generation of Erema melt filters as well as the superior HG 82/152/242/342 Erema hot die face pelletising systems (see separate brochures) offer the processor a superior machine with unsurpassed performance, reliability and productivity.
* DD stands for "Double Disc" Technology and refers to the separation of the working steps "material processing" (shredding, drying, preheating, compacting) from the step "extruder feeding" in the cutter compactor. The result is an extremely uniformly fed and evenly operating recycling extruder which constantly performs at its best, regardless of external factors (e.g. feed portion size, moisture etc.).
How the system works:
The direct combination results in energy savings of up to 40% compared to multi-stage-processes. In the extruder the material is plasticised, homogenised and, if necessary, vented (TE, TVE plant type).
Extruder configurations:
- Type 1 = basic type (T-plant) = extruder without degassing zone
- Type 2 = cylinder degassing upstream of filter (TE-plant) = classic degassing extruder with double venting.
- Type 3 = filter upstream of cylinder degassing (TVE-plant), patented, double vented extruder with supreme degassing efficiency (see separate brochure)
