The EGR pelletizer is designed to process temperature- and shear-sensitive plastics with maximum care, ensuring consistently high pellet quality. Thanks to an optimized air supply system, pellets are conveyed at significantly lower feed pressure for gentler material handling and reduced risk of agglomerate formation.
For operators, the design delivers major efficiency gains. Energy consumption for material conveying is reduced by up to 75% compared with the previous model, lowering operating costs while helping to reduce the overall CO₂ footprint.
The EGR pelletizer features a redesigned die plate heating system that can be easily separated from the die plate, making assembly and disassembly significantly faster. This provides a clear advantage during recipe changes, reducing downtime and simplifying maintenance.
In addition, faster heat-up times help minimize production delays and keep operations running smoothly. Together, these improvements increase uptime for both the EGR and the entire compounding system, enhancing overall equipment effectiveness (OEE).

With the two-stage Kombiplast compounder and the EGR eccentric pelletizer, Coperion offers a system solution specifically engineered for processing temperature- and shear-sensitive materials such as PVC and cable compounds. The technology ensures exceptionally gentle product handling throughout the entire compounding process while delivering high efficiency, maximum flexibility, and reliable product quality.
In the first process stage, raw materials are fed into the processing section of a ZSK twin screw extruder via a ZS-B twin screw side feeder. Within the extruder, the material is conveyed, plasticized, mixed, and homogenized under carefully controlled conditions. Thanks to the advanced ZSK Mv14 design with increased torque of 14 Nm/cm³, the system enables especially gentle processing while achieving high throughput rates.
The product is then discharged through the ES-A single screw extruder, which builds the pressure required for the downstream pelletizing stage.
During pelletizing, the EGR eccentric pelletizer cuts the cylindrical strands emerging from the die plate into uniform pellets using rotating pelletizing knives. The pellets are subsequently discharged through pressure conveying, supported by specially developed inflatable seals.
The pelletizing knives are mounted on a blade positioned eccentrically to the die plate, allowing infinitely variable blade speed adjustment. To ensure optimal pellet quality, Coperion customizes the number, diameter, and geometry of the die plate holes to match specific material characteristics and individual customer requirements.
