Coperion's ZS-B MEGAfeed Side Feeder

ZS-B MEGAfeed Side Feeder

Both in the recycling of post-industrial waste and in the reprocessing of post-consumer waste, the ZS-B MEGAfeed technology opens up completely new dimensions. The ZS-B MEGAfeed achieves an immense increase in the feeding rate of flakes and fibers from a wide variety of plastics (e.g. PA, PE, PET, PP), and thus significantly higher throughput rates - in both mechanical and chemical recycling.

Side Feeder ZS-B

The ZS-B twin screw side feeder for ZSK extruders enables the side feeding of fillers and additives in powder or pellet form or cut glass fibers into the processing section of the twin screw extruder. The ZS-B features a self-cleaning profile of the twin screws and product feeding into the screw flights of the extruder without stagnant zones. Very little space is required for the side feeder thanks to its compact design.

It can be mounted anywhere on the extruder’s process section with a side feed or combi barrel. It is available in mobil and a pivoting design.

For much faster dismantling from the ZSK process section and simple change of the twin screws Coperion offers the ZS-B in easy design.

Coperion Feed Enhacement Technology FET

Feed Enhancement Technology (FET)

In this patented technology the feeding zone of ZSK extruders is equipped with a porous, gas-permeable wall section to which a vacuum is applied externally. The resulting gas extraction increases the material intake capacity in the processing of feed limited products by up to three times.

The results of the FET technology are considerable increases in the throughput rate and greater cost effectiveness of the compounding plant.

Coperion side devolatilization ZS-EG

Side Devolatilization Unit ZS-EG

The performance capability of the ZSK and the STS series with a conventional top vent barrel can be limited in many cases especially in the extrusion of low-viscous melts and extrusion processes with high gas volumes.

The ZS-EG twin screw side devolatilization provides the solution for ZSK and STS extruders. With its large free cross section for the devolatilization, it keeps the melt reliably in the process section during operation without product leakage even at maximum specific torque of the extruder. Throughput increases of up to 30% with, at the same time, considerably improved product quality are possible.

It is available in mobil and a pivoting design. For reduced time for cleaning Coperion offers the ZS-EG in easy design.

Coperion melt pump MP

Melt Pump MP

Use of a melt pump is necessary in individual cases for processing and pelletizing polyolefins. It ensures the necessary pressure build-up for the melt filtration and pelletizing at a very low introduction of energy. The Melt Pumps MP from Coperion are adapted individually to the project requirements as well as the ZSK MEGAcompounder.
