Plastics Feeding & Compounding Videos

Plastics Recycling Technology

Coperion’s plastics recycling experts Franz Neuner, Director of Product Management | Equipment & Systems Division and Jochen Schofer, Business Segment Manager Recycling & Direct Extrusion | Polymer Division, met at Aurora Kunststoffe to exchange ideas on plastic recycling. In this short interview they explain why circular economy is becoming increasingly important for the plastics industry and for which recycling applications Coperion offers technology solutions.

PET Recycling

Coperion’s plastics recycling expert Jochen Schofer talks about the complex procedure of PET recycling and explains how it can be simplified by using twin-screw extruders.

Twin-Screw Compounding

Coperion’s plastics recycling expert Jochen Schofer explains what is important in plastics recycling and why twin-screw extruders are particularly well suited for successful plastics recycling.

Bulk Feeding and Handling of Secondary Materials

Coperion’s plastics recycling experts Franz Neuner and Steffen Bader talk about technological challenges in feeding and handling bulk secondary raw material. Franz Neuner addresses the challenges of feeding and Steffen Bader talks about the different conveying methods that Coperion offers for bulk secondary raw material.

This animation flies you through the 3-D model of one of Coperion K-Tron’s individual process solutions in the plastics industry. The facility includes bulk material handling and transfer, ingredient weighing, feeding, mixing and extrusion. The film features railcar and truck unloading, material transfer to and from silos, dilute and dense phase pneumatic conveying, batch weighing for major ingredients with the loss-in-weight (LIW-) method, batch weighing for minor ingredients with the gain-in-weight (GIW-) method, batch mixing for major and minor premixes, a continuous mixing stage, the extrusion stage with powder and liquid weigh feeding and, finally, the fully integrated device and system controls.

3-D animation of a Coperion process solution in a polyolefin production. Coperion is expert for high-capacity polyolefin manufacturing plants. Whether it is a matter of continuously stabilizing, homogenizing and pelletizing LLDPE, HDPE or PP powder or concentrating a melt solution, we have unique know-how and a wealth of experience in providing high-performance compounding systems as well as bulk material handling plants for the polyolefin industry.

3-D animation showing the Coperion K-Tron ActiFlow™ bulk solid activator keeping bulk material moving in a twin screw feeder. This clever device prevents bridging and ratholing of bulk material being discharged from a hopper by a feeder in an industrial manufacturing process. Owing to its tight integration with the feeder control it acts preventatively and only when required and thus does not additionally compact the bulk material. Furthermore it is completely non-product-contact and maintenance free which makes it especially suitable for food or pharma applications.

3-D animation illustrating the principle of operation of Coperion K-Tron’s Smart Flow Meter ‘K-SFM’. This highly accurate flow meter is used mainly in manufacturing processes in the plastics and chemicals industries. It serves for the reliable feeding, metering or monitoring of solid bulk material flows and represents an ideal alternative to traditional feeder configurations with, for example, feed screws or belts. The K-SFM has no moving parts, thereby ensuring gentle handling of the bulk material - a distinct advantage over other flow meter technologies. The simple, yet robust design allows the K-SFM to provide an accurate measurement in most environments.

Short movie showing step-by-step how to change the feeding belt in a Coperion K-Tron Smart Weigh Belt Feeder (SWB). The film also points out some features of this device and lists available options. Weigh belt feeders are relatively simple, extremely reliable gravimetric feeders providing high feeding precision and efficient process monitoring in industrial manufacturing processes in industries such as plastics, chemicals, food, pharmaceuticals, or minerals. The SWB is the perfect solution for wild flow metering, in locations where headroom is limited, or when feeding friable material that may be damaged by other feeding methods.


Hanging Feeder Design with 3-Point Weighing
Video shows Coperion K-Tron's 3-Point weighing system featuring Coperion K-Tron's K-SFT-II load cells. Hanging loss-in-weight feeders are ideal for mounting directly over process equipment. Video also shows the K2-ML-T35 twin screw feeder. Hanging bowl design allows processors to access screws, seals and internal surfaces for cleaning. 
Bulk Solids PumpTM Feeder line
Using Positive Displacement Feeding Technology, the Bulk Solids Pump (BSP) does not use screws, augers, belts or vibratory trays to convey material. Free flowing materials are fed via a rotating channel, delivering a true mass flow as the materials are positively displaced from inlet to outlet.
Cone Feeder
Video shows a screw-less feeder design for the low rate addition of additives. Feeder utilizes a induced flow rotating cone, designed to dose down to few granules at a time and up to 2 dm3/hr (122 in3/hr or .07 ft3/hr) of normal masterbatch. Wth the use of an extension tip, the feeder can feed as low as 0.1 dm3. The minimum disersive rate is > 2 pellets per second.
