Extrusion Asia Edition 2-2025

38 EXTRUSION & RECYCLING ASIA 2/2025 K 2025 C operion, together with Herbold Meckesheim, will present their expertise in various plastics recycling applications at this year’s K show. At Booth 9B34 in Hall 9, the focus will be on Herbold Meckesheim’s technologies for mechanical processing of plastics waste. On display will be the new T 150-300 Mechanical Dryer and the SMS 80-200 Granulator. In the Open Area, Pavilion FG/CE07, visitors can witness the seamless interplay of all Coperion recycling technologies. On view will be a Herbold Meckesheim Hydrocyclone Stage, the ZSK FilCo filtration compounder, the ZS-B MEGAfeed side feeder, a Coperion K-Tron K3-V200 vibratory feeder, an S60 single screw feeder and the MechaTron® at bottom feeder. Also on display will be a mobile deodorization unit for reliably removing unpleasant odors from recyclates. In addition to plastics recycling, Coperion specializes in plastic compounding technologies. These core competencies will be on display at Booth 14B19 in Hall 14. High performance using ZSK FilCo with ZS-B MEGAfeed In the Open Area, Pavilion FG/ CE07, Coperion will exhibit its new ZSK FilCo ltration compounder which enables recyclate ltering and sub- sequent compounding in one step. In comparison to two-step production lines, the ZSK FilCo handles the prod- uct very gently and provides higher quality at signi cantly reduced energy consumption when recycling post-con- sumer waste and other highly contam- inated polymers. Waste plastics in the form of regrind, ber pellets, lm akes or agglomerate with no pre-treatment are introduced into a ZSK twin screw extruder where they are melted, ho- mogenized and devolatilized. The melt is then fed through a lter, removing any contaminants. In the subsequent compounding process additives are introduced into the melt prior to pellet- izing the compound. To fully exploit the ZSK FilCo’s high performance, raw materials must be supplied at a constant rate with no intake limits. While this can be ac- complished either by pelletizing the waste plastic or regrind, or by us- ing a compacting process, these are very energy-intensive processes and increase both capital and operating costs. In contrast, the ZS-B MEGA- feed side feeder, on display in Pavil- ion FG/CE07, reliably feeds recycled materials with a bulk density as low as 20 kg/m³ into the ZSK FilCo and other ZSK extruders. This allows for recy- cling and compounding of lightweight, high-volume bers and akes at high throughputs. Seamless connection of bulk material handling and feeding technology Coperion is an expert in numerous feeding technologies that stand out with their high-accuracy and easy han- dling. Representative of this expertise, in Pavilion FG/CE07 Coperion will display a Coperion K-Tron K3-V200 vibratory feeder that excels in provid- ing high-accuracy gravimetric feeding particularly for challenging materials, for example where smaller recyclates or akes are being fed into the extru- sion process. For light and u y, hard- to-feed materials such as polypropyl- ene or PET plastic lm, Coperion will showcase the MechaTron FB ( at bot- tom) feeder, a gravimetric feeder ideal for high-capacity recycling operations. Also on display is the Coperion K-Tron S60 single screw feeder, another feed- er the provides very high reliability. Coperion developed its ZRD rotary valve especially for plastics recycling processes. Together with the new drive technology, the new design of the gap between the rotor and housing ensures reliable discharge of akes. Entire lines from a single supplier At K 2025, Coperion will demon- strate how its various technologies work together through an all-encom- passing 3D simulation. Visitors will gain insights into the operation of a complete system as well as the func- tion of each individual component. All of Coperion’s components and tech- nologies are characterized by high throughput, excellent end-product quality, and exceptional e ciency. For example, Coperion recently success- fully commissioned chemical plastics recycling lines at two customer facili- ties, both capable of processing up to 6,000 kg/h. Even when recycling PET, proces- sors pro t from Coperion’s expertise in engineering complete systems, achieving very good end product qual- ity, and providing high throughputs. Pre-drying the PET akes is not nec- essary thanks to the e ective degas- sing in the Coperion process. A few weeks ago, Coperion and Herbold Meckesheim installed the rst stage of a bottle-to-bottle recycling plant at Magpet Polymer Pvt Ltd in India. The successful startup of the granulators and washing line marks an important step toward launching the full plant, which is designed to process up to 5,500 kg/h. Likewise, the bene t of such end- to-end line expertise is evident in the e ective removal of unwanted odors. All along the entire recycling process, Coperion o ers various solutions for reliably deodorizing post-consumer plastics. Odor removal in mechanical processing, devolatilization in the twin screw extruder, and Coperion’s Eco- Fresh Silo devolatilization solutions are available to observe. The interplay of these technologies reliably ensures the desired product quality. Coperion recently installed the EcoFresh silo devolatilization at its Recycling Inno- vation Center. There, customers can thoroughly test various odor removal technologies using actual products un- der near-production conditions before making an investment. This allows them to ensure that the nal process meets all quality requirements. Coperion www.coperion.com Hall 14 Booth 14B19 , Hall 9 Booth 9B34, FG/CE07, Open Area "The Power Of Plastics Forum"
