rotor makes it possible to produce extremely low-dust or elastomer-based cable compounds. Coperion can draw
PVC pellets for cable manufacture. Rotating directly on decades of experience in the design and construction
on the die plate of the EGR, and fitted with pelletizer of complete plants for the processing of temperature
knives that have also been optimized, the rotor (patent
pending) permits particularly smooth and gentle cutting and shear-sensitive materials – from material handling
of temperature and shear-sensitive plastics. and feeding, to dry blend production, compounding, and
pellet cooling, to storage and filling.
