plastics applications,” said Robert Obermayr, head of Erema’s Powerfil subsidiary. The Quattro version of the LF 406 laser filter can filter up to 9,000 kg/hr of melt. “Plastic recycling has become a must-have, even for input streams with higher levels of contamina- tion,” said Obermayr. “Efficient filtration systems are indispen- sable for achieving the specified melt quality using existing extrusion systems.” For this reason, the company
offers the melt filters as individual components for existing Erema machines and third-party extrusion systems. The product range includes the SW RTF partial area backflush system and the laser filter. Both types of filter are easy to integrate into an
existing recycling plant and available in many sizes and variations. Whether the customer uses the backflush filter or the continuous laser filter depends on the throughput and level of contami- nation of the material. The laser filter is ideal for heavy contamination, says the company – and can handle impurity levels up to 5% and filtration as fine as 70 microns while continuously cleaning the screen with a scraper.
Models on display Gneuss exhibited several different models of its patented rotary filtration systems at K2022. These are characterized by a filter disk on which the
screen cavities are located in a ring pattern. Screens can be changed on the part of the filter disk that is not active in the melt channel, while production contin- ues without interruption. Its main model, the RSFgenius, has an integrated back-flushing system offering self-clean- ing for demanding applica- tions. Screens can be automatically re-used up to 400 times and filtration fineness below 10 microns/1200 mesh is
available. An RSFgenius 250 was on display at
K2022. It has an active screen area of 1350 sq cm and throughputs of several thousand kilos per hour, depending on the type of polymer and the filtration fineness. Retrofitting an RSFgenius to an existing extru- sion line allows the use of more contaminated – and often cheaper – material, says Gneuss. There was also an SFneos 150 and SFXmagnus 90 on display. These are also continuous, pressure and process constant, but not backflushing – so the systems are for applications that do not require self-cleaning.
