Coperion and Herbold Meckesheim at NPE 2024
Coperion and Herbold Meckesheim will present combined process solutions and technologies for plastics recycling at NPE 2024, which will take place in Orlando, the US, on May 6-10.

Coperion and Herbold Meckesheim will present technologies for plastics recycling at NPE.
ZSK twin screw extruder
On display will be a ZSK 58 Mc18 twin screw extruder configured for manufacturing high-quality PET using recycled materials. ZSK extruder offers very good devolatilization properties, volatile components such as monomers, oligomers and water are reliably removed.
The high quality of recycled PET manufactured by this technology was approved by the US FDA for direct contact with food.
Coperion’s ZS-B 70 MEGAfeed side feeder
At NPE, Coperion will show the recently-introduced ZS-B 70 MEGAfeed side feeder. The side feeder is used for feeding voluminous flakes and fibers (PET and other plastics) efficiently into a ZSK twin screw extruder.

Plastic recyclate with bulk density from as low as 20 kg/m³, which are commonly considered intake-limited and thus not worth recycling, can be directly fed in large quantities into smaller sizes of Coperion’s ZSK twin screw extruders, and can then be concurrently recycled and compounded.
Herbold Meckesheim’s HV 70 plastcompactor
Also on display will be Herbold Meckesheim’s HV 70 plastcompactor. It processes the feedstock in continuous operation between a rotating and a fixed compactor disk, which are equipped with screwed-on and easily exchangeable kneading bars.

The processor can be used to agglomerate a wide variety of materials into products of high bulk density – thermoplastics, such as fibers, fine particles, small tapes, foams, stretch or thin films, powders or shavings, and plastics that are difficult to convey, stock or mix.
With a fully automatic control system that record settings for different feedstocks, HV 70 offers high throughput and low wear costs. It also allows a minimum of personnel due to performance and temperature monitoring.
Schenck Process FPM MechaTron Flat Bottom feeder
In addition, the Schenck Process FPM MechaTron Flat Bottom (FB) feeder will be displayed at NPE. This high-capacity stainless steel feeder is specifically designed for handling materials with light and fluffy characteristics.

With a bottom driven vertical agitator and an auxiliary agitator, the MechaTron FB is well-suited for hard to feed materials such as chopped polypropylene or PET plastic film when feeding to an extruder.
Since Schenck Process FPM has become part of Coperion in 2023, both brands jointly present their products for the first time at this NPE.
