Coperion and Coperion K-Tron will be presenting a variety of new and ongoing developments at their Booth B19 in Hall 14 that will markedly increase the efficiency of plastics compounding processes, help boost conscientious resource handling while at the same time achieving very high product quality.
Moreover, the company is creating a space dedicated to the forward-looking topic of “Plastics Recycling”. Coperion will be exhibiting an entire production line for recycling polyethylene terephthalate (PET)
at their booth within the VDMA’s Circular Economy Forum, a pavilion on the open-air fairgrounds (CE09).
Coperion Recycling Pavilion
Exhibits will encompass bulk solids handling, feeding, extrusion, and pelletizing, all representing Coperion’s advanced expertise in numerous plastics recycling processes such as chemical recycling
, multilayer film recycling, and upcycling. Trailblazing new developments from Coperion, such as the ZS-B MEGAfeed side feeder that enables plastic film and flake recycling in very high throughput dimensions, will be center stage at the Coperion Recycling Pavilion.
One eye catcher at the Coperion Booth B19 in Hall 14 will be the high performance ZSK Mc18 extruder with a 70 mm screw diameter. With its high specific torque of 18 Nm/cm3, it is especially suited for efficient compounding of plastics at very high throughput rates and with comparatively low energy consumption.
The ZSK extruder is equipped with a ZS-B easy side feeder as well as a ZS-EG side devolatilization unit. Both the ZS-B as well as the ZS-EG – thanks to their simple design – significantly reduce the time needed for recipe changes or maintenance tasks, since they can easily be removed from the process section in just a few steps.
A K3-ML-D5-V200 vibratory feeder from Coperion K-Tron will be on display at the main intake of the ZSK 70 Mc18. The ZS-B easy will be equipped with a K-ML-SFS-BSP-100 Bulk Solids Pump™ (BSP) feeder.
Another highlight at the Coperion booth will be the STS Mc11 series laboratory extruder with a 25 mm screw diameter. It stands out with its simple design, user friendliness and easy cleaning. Its Do/Di of 1.55 and specific torque Md/a3 of 11.3 Nm/cm3 allow for safe scale-up across the entire STS Mc11 series. The STS 25 Mc11 will be exhibited with a Coperion K-Tron K-ML-SFS-KT20 twin screw feeder.
Moreover, the new, preconfigured ProRate PLUS feeder line will be available to view in all three available sizes: small, medium, and large. This continuous gravimetric feeder from Coperion K-Tron is very robust, and thanks to its good price-performance ratio is an economical solution for reliable feeding of free-flowing bulk materials.
One further highlight of Coperion’s showing at K 2022 will be the ZXQ 800 rotary valve. This high-performance valve, which works with especially low gas leakage, was developed by Coperion especially for powder intake into pneumatic conveying lines at up to 3.5 bar. Thanks to its enormous capacity, it is very well suited for systems planned for polyolefin manufacturing in the future.You might also be interested in materials and technologies innovating plastic recycling.
High Quality Products with Economical Recycling
Plastics recycling is the focus of comprehensive development projects at Coperion. The company will show the results of these projects at K 2022 in its pavilion on the open-air fairgrounds (CE09) within the VDMA Circular Economy Forum.
There, Coperion will present its combined process solutions and technologies for the economical recycling of various plastics while achieving the highest levels of product quality. At the center will be a system built around a ZSK 58 Mc18 twin screw extruder configured for manufacturing high-quality PET using recycled materials.
For feeding voluminous flakes and fibers (PET and other plastics) efficiently into the ZSK twin screw extruder, Coperion will show the SWB-300 Smart Weigh Belt Feeder with a S100 single screw pre-feeder, as well as the new ZS-B 70 MEGAfeed side feeder. The SWB is an extremely reliable gravimetric feeder from Coperion K-Tron that can process large volumes of bulk materials with a wide variety of flow properties at very high accuracy.
Using the innovative, newly developed Coperion ZS-B MEGAfeed, plastic recyclate with a bulk density under 200 kg/m³, long considered intake-limited and thus not worth recycling, can be reliably fed in large quantities into smaller sizes of Coperion’s ZSK twin screw extruders and be concurrently recycled and compounded.
Marina Matta, Team Leader of Process Technology Engineering Plastics at Coperion, said: “Plastics recycling is one of the core topics that we are emphatically promoting in order to better support the plastics industry on its path to a circular economy. We are very proud of our newly developed technologies and processes that achieve first-class product quality and make plastics recycling significantly more efficient. Source: Coperion
