Examiner for improving the output quality in PE film washing systems. Placed directly in front of the extrusion phase as a final process to improve product quality, the company says that the device reliably separates small, hard contamination particles that are extremely difficult to remove using traditional methods within the wash line due to their specific density and size. In particular, these include rigid plastic particles of PP or HDPE, and in addition light aluminium particles and small wood flakes. The Film Examiner is mounted directly in the air


stream after the thermal drying process, utilising the different flow characteristics between small contaminants and the light film flakes in order to achieve reliable separation. The air flow is adjustable by means of sliding gates in order to optimise the separation process. The separated contaminants fall into a collection bin, which can be easily monitored and emptied. “Improving output quality is our customers’ focus today,” says Georg Krenn, Technical Manager at Lindner Washtech. “The Film Examiner without doubt provides a compact and inexpensive solution to further improve product quality and reduce operational costs, supporting our customers’ key goals. Retrofitting existing plants with the Film Examiner is fast, easy and highly cost-effective.” Lindner Washtech adds that it now has over 50 washing systems installed worldwide for PE film recycling. Other new developments, such as the Rafter pre-washing system, are now an integral part of every Lindner washing system. Lindner Washtech has also installed a new


treatment plant for Slovenian recycler Dinos. Inaugurated in February 2020 in Ljubljana, the recycling plant processes industrial plastic waste and plastic foil in particular. The new facility includes a universal washing system from Lindner Washtech with a range of new and improved components, such as a Micromat 2000 shredder, a pre-wash Floater extend unit and a mechanical dryer from the Loop Dryer series. The washed flakes are regranu- lated by an Erema Intarema 1714 TVEplus extruder. With 19 waste depots in operation, Dinos is one


of the largest waste management and recycling companies in Slovenia. The company collects and recycles non-ferrous materials (glass, wood, plastics and paper), metals (all types of old and

new industrial scrap, steel, stainless steel and cast iron) and non-ferrous metals (aluminium, copper, nickel and tin). After collecting the waste material, it is sorted and processed. Dinos has been part of the German Scholz Group since 2012. “In the past 15 years, Dinos focussed mainly on collection and pressing or shredding of waste from the plastics sector,” says Jure Jambrovic, Plant Manager. “However, due to the changing situation in the world market where placement of plastic waste has become increasingly difficult, we have decided to start our own recycling line. This will enable us to offer the market a high quality


end product.” The primary materials processed


are LDPE and LLDPE clear wrap (mainly packaging films from the industrial sector and supermar- kets), LDPE mixed films (post-consumer), HDPE drums and HDPE canisters (primarily post-commercial packaging) and PP (crates and packaging). “Our facility is a multi-purpose line for washing and regranulation of LDPE and


HDPE/PP rigid plastics,” says Product


Manager Andrej Gustin. “We currently recycle post-commercial films, which we process in four stages – shredding, washing, drying and regranula- tion. The plant can process a capacity of approxi- mately 8-12 tonnes of regranulate per 8-hour shift.” Lindner Washtech adds that the Micromat 2000


shredder can be used universally for shredding hard plastics and plastic films reliably. In particular it is characterised by its consistently high productivity and homogeneous output. There are no process fluctuations due to the new RAMS Professional
