The advantages of recycling and compounding united in a powerful system that saves time and energy. Recycling raw material such as PP fleece, PE edge trim and PA fibres is turned into a filtered melt by EREMA technology and then fed directly to the co-rotating twin-screw extruder.

With its excellent mixing and gas removal properties, this part of the system can handle all compounding tasks. Besides the dosing of a wide variety of additives, large amounts of fillers and reinforcing agents can be admixed. The result is customisable recycling compounds for especially high-grade applications.

Possible materials

It's amazing what you can recycle with COREMA®. Here are some examples.

Multiple-layer films (e.g. PET/PE) Multiple-layer films (e.g. PET/PE) PP regrind material + colour masterbatch + fibreglass PP regrind material + colour masterbatch + fibreglass Washed film flakes + colour masterbatch + CaCO3 Washed film flakes + colour masterbatch + CaCO3

Your benefits

Economical and technically better.

Flexible input of various recycling raw materials thanks to the preconditioning unit and Counter Current®

Increased value added thanks to the use of inexpensive raw materials (e.g. PP fleece, PE edge trim, PA fibres etc.)

Proven, robust EREMA technology for producing filtered melt material

Modular system concept ensures a perfect fit for every application

Very low operating costs and minimal specific energy costs through direct dosing of the filtered melt and processing “in a single heat”.

Minimum thermal stress through short, defined dwell times and direct dosing of the melt in the twin-screw / compounder / extruder

Reliable, high output thanks to Counter Current technology and extremely robust design

Proven EREMA degassing technology with EREMA preconditioning unit and extruder degassing

Up to

12%

lower energy consumption, lower production costs and CO2 emissions thanks to ecoSAVE®

Central user interface to control the whole system

Compact, space-saving design

How it works

COREMA®

How COREMA works 1 2 3 4 5 6 7 8 9

Feeding (1) is automatic and according to customer requirements. In the patented preconditioning unit (2) the material is cut, mixed, heated, dried, pre-compacted and buffered. Next, the tangentially connected extruder is filled continuously with hot, pre-compacted material.

In the extruder screw (3) the material is plasticised, homogenised and then cleaned in the fully automatic self-cleaning filter (4).

The prepared and cleaned melt then goes via the melt pump (5) directly to the Coperion co-rotating, self-cleaning twin-screw extruder (6). With its excellent mixing and gas removal properties, this flexible part of the system can handle all compounding tasks.

Besides the dosing of a wide variety of additives, large amounts of fillers and reinforcing agents can be admixed (7). In the degassing zone (8) the compounded melt is degassed and then fed into the respective system (9) (e.g. EREMA hot die face pelletising system).
