Fimic’s Era
2016 | Recycling technology The ‘open hearted’ design enables quick, direct
filter has two filtering chambers
access to the shredder rotor and cutter chamber, which simplifies cleaning and servicing. The front door, hinged on the side, gives unrestricted access to the rotor and screen, which is mounted in the door. Once the door is open, the shredder hopper mounted on a rear hinge can be tilted back. Rapid offers 36 base configurations of the Raptor in
order to handle various customer applications. The modular systems feature two diameters and two widths – 31.5in (800mm) and 53in (1,350mm). There are two system designs for pushing material into the rotor – FlexiPush and PowerPush. PowerPush is available with an extended pusher length (PowerPush-XT). The FlexiPush is a pneumatically driven pusher for handling basic applica- tions, including lumpy materials. It
can handle large products such as a 1,200 litre IBC, for example. The hydraulically powered PowerPush maximises output for shredding sheet and film. The cutting chamber features a textured floor
to reduce the risk of material adhering or finding its way under the pusher and is offset by 5 degrees to enable liquids to drain away. There are also three cutting
systems: Quad Cut, Claw, and Power Wedge. The QuadCut cutting system for general plastic waste features a solid

knife that allows full use of all four cutting edges. The cutting system is durable and has a solid clamping system attaching the knife to the rotor. The knives are supported by a sacrificial washer in order to protect the rotor should non-plastic material accidently enter the cutting chamber.

Melt filter efficiency Ettlinger will use K2016 trade fair to showcase an enhanced range of high-efficiency melt filters. Its ERF series, which is suitable for heavily contami- nated plastics, can now handle higher throughputs. The patented, continuously operating ERF melt
filters can be incorporated into almost any extrusion line. At the heart of both types is a rotating filter drum with conical perforations, through which the contaminated melt flows from the outside to the inside. Fimic has developed a new filter that is aimed
specifically at PVC processing. Its RAS technology is based on collecting a high level of contamination inside a hollow blade holder, and discharging it based on a

pre-set pressure. Because of the level of contamination – usually
above 20% – the machine is set in continuous mode, so that the blade holder keeps slowly scraping the stainless steel screen and gradually accumulate the removed contamination. Fimic has also developed the Era filter, which filters
twice in sequence. It is aimed at highly contaminated material, which requires two filtering stages in order to obtain a usable material. At the same time, Fimic will present a third filter model: its NET filters will use a metal mesh that filters continuously without any stop – and with no need to modify the extruder. Nordson has developed a new melt filtration system
for recycling highly contaminated plastics – saying it provides greater productivity than comparable ma- chines while maintaining constant melt pressure and product consistency. The BKG HiCon R-Type 250 transforms contaminated
polyolefin or styrenic plastics into clean, high-quality material, and exhibits less melt loss than traditional backflush systems, says Nordson PPS business unit
