Centric pelletizer for direct extrusion
Effortlessly transform materials into uniform granules with our high-speed pelletizing solution, ensuring precise control over pellet length and consistency across vast throughput scenarios.

Pelletizes and Cuts Extruded Materials
The Centric Pelletizer ZGF Series from Coperion is engineered to enhance pelletizing efficiency for a wide range of industries, including food, pet food, chemicals, and pharmaceuticals. What sets this equipment apart is its precise knife rotor system, which centrally aligns to the die plate, cutting extruded products directly at the end of the extruder. This configuration ensures uniform pellet length and maintains high product quality. Ideal for producing cornflakes, fish pellets, dog kibble, polymer pellets, and pharmaceutical tablets, the series supports continuous, high-speed operations with adjustable pellet length through variable knife speeds. The ZGF Series integrates seamlessly with twin screw extruders, connected via quick release mechanisms for fast assembly and disassembly, minimizing downtime in your production line. Its stainless steel construction provides corrosion resistance, suitable for various operational environments. Moreover, the pelletizer comes equipped with a safety feature to ensure the hood remains closed until the motor stops, enhancing operational safety. Customization options, such as the number of knives and rotor speed, allow you to tailor the machine to specific production needs, supported by Coperion’s engineering expertise.
