At IFAT 2024, Coperion and Herbold Meckesheim will be presenting innovative product and process solutions that make the recycling of plastics significantly more efficient and considerably increase the product qualities achieved. The added value resulting from the merger of Herbold Meckesheim, the specialist for mechanical recycling of plastics and plastic waste, and Coperion, the expert for bulk material handling, dosing, extrusion and compounding, can be experienced by visitors to the trade fair stand with a virtual complete system for recycling PET.
This virtual plant presents one of the complete solutions for plastics recycling that Coperion and Herbold Meckesheim are realizing together. It shows the overall process and at the same time provides an in-depth look at numerous key components and how they work.
In addition, rotors from Herbold granulators in various designs for a wide range of applications will be on display at the stand. In the rotor concept, the cutting geometry is primarily responsible for the high efficiency of the mills from Meckesheim.
Plastic recycling systems from a single source
In addition to individual components, Coperion and Herbold Meckesheim are now jointly realizing complete systems for the recycling of plastics. From mechanical processing – shredding, washing, separating, drying and agglomerating plastics – to bulk material handling, dosing, extrusion, compounding and pelletizing, such complete systems cover the entire process chain in plastics recovery. Since their merger, the two companies have intensively developed the technologies for the individual process steps and optimally coordinated them so that the overall systems are characterized by a very high level of efficiency in operation.
Depending on the type of plastic to be processed, Coperion and Herbold Meckesheim implement solutions for the mechanical recycling of post-industrial and post-consumer waste, for chemical recycling, solvent-based recycling and for deodorization.
The right rotor geometry for every application
Decisive for the high efficiency of Herbold granulators are the rotor concept and the cutting geometry, which is individually adapted to the task and the starting material. Granulators from Herbold Meckesheim work with a genuine double diagonal cut: not only are the rotor knives arranged at an angle, the stator knives are also mounted at opposite angles. This produces a clean cut with a constant cutting gap across the entire blade width. The end product is a regrind with very good flowability, low fines and a high bulk density. Three different rotor types from Herbold Meckesheim will be exhibited on the stand as examples.
