Advanced mixing technology for chemical plastic recycling
The goal for efficient plastics recycling needs to not only return pure, but also compounded polymers to a cycle. Thus, chemical plastic-recycling processes must be established on a large scale. Depending on the recycling process, very high viscosities or even higher rheological challenges, such as yield points, are to be expected. Efficient stirring technology is necessary to handle this quite sophisticated combination of mixing tasks. As an example, With the Paravisc impeller system (photo), for example, axial mixing is achieved through the unique shape and arrangement of the two main blades, even managing high product viscosities. Processes with different types of plastic waste can be tested and optimized under realistic conditions on a technical scale in the company’s technology center, or in pilot plant. Based on the findings from pilot tests, a complete reactor system can be tailored to the needs of the user. Hall 11, Stand A65 — Ekato Process Technologies GmbH, Freiburg, Germany
