High-capacity extruders for polyolefins

The twin screw extruder ZSK MEGAcompounder from Coperion is considered a milestone in the development of the high-performance compounding plants for the production of polyolefins. The extremely high productivity of the system is the result of more than 60 years of continuous research and development.

The ZSK MEGAcompounder series is ideally suitable for the economical processing of polyolefins. It constantly achieves maximum product quality especially in continuous processes with a high energy requirements. Its modular design principle allows optimal adaptation to every process. Whether it is a matter of continuously stabilizing, homogenizing and pelletizing LLDPE, HDPE or PP powder or concentrating a melt solution – with our many years of knowhow we configure the ZSK MEGAcompounder and the system auxiliary equipment to your individual process requirements. You achieve maximum throughput rates with the greatest possible cost effectiveness and the highest product quality with our systems.

The current series features a specific torque of 12.5 Nm/cm3. This brings polyolefin processing to the throughput rate of 135 t/h and beyond.
