Gneuss’ MRS Extrusion Technology has proven itself as an alternative for the reprocessing of contaminated materials like polyester, nylon, polystyrene, polypropylene or other polymers. In combination with the highly efficient Gneuss Rotary Filtration Systems and optimized vacuum technology, customizable recycling lines tailor-made for a specific material can be engineered. Several Letters of Non Objection (LNOs) from the FDA, EFSA conformity and local approvals in Latin America confirm the decontamination efficiency of the technology. 3C Rotary Feeder The newly developed 3C Rotary Feeder makes it possible to use low bulk density materials without any external processing steps. A conveyor belt feeds shredded reclaim material into the hopper, where a fast-rotating disc with knives cuts, compacts and pre-conditions the material. The knives add energy into the material and start the heating and degassing process before the material is automatically fed into the extrusion system. Extrusion system In most cases, the patented multiple screw Gneuß MRS extruders is applied. Thanks to the sturdy satellite screws, the degassing and homogenising performance of the extruder is second to none. The vast polymer surface area under vacuum in the MRS section of the extruder ensures highly efficient decontamination, homogenisation and control of the viscosity (in particular when reprocessing PET). Alternatively, the new (and likewise patented) MDS extruder can be applied for certain applications. This extruder is characterised by a new kind of combination of heat input and devolatilization. Thanks to the changes in the extruder screw diameter, a unique new combination
