SHOW PREVIEW | FAKUMA 2017
Right: ECON’s EUP 10
pelletiser is designed for laboratory applications
hopper technology. This uses a flow aid to gently vibrate the hopper walls to prevent bridging and rat-holing. Operation is integrated into the feeder control to ensure minimal risk of compaction of the bulk material. Actiflow is available as a retrofit option and can be supplied in ATEX versions. Coperion’s Fakuma display will also include its
Electronic Pressure Compensation (EPC) system. Designed for use in high-accuracy loss-in-weight feeders, this electronic system ensures accurate and steady pressure compensation in feeder hoppers and outlets and is said to be easier and less costly to install than traditional mechanical pressure compensation systems. It integrates with Coperion K-Tron’s KCM feeder control system and can be retrofitted to existing feeders. �

business unit will market the company’s Laserfilter melt filters
ECON’s display at Fakuma will focus on its updated EUP 10 pelletiser, its smallest system with an output of 1-30 kg/h intended for laboratory applications. The machine now includes an elastic rubber coupling for improved production stability and pellet quality, a hydraulically controlled diverter valve for more reliabile operation, and an uprated pelletiser drive that near doubles maximum speed to 5,000 rpm. The new unit can also produce micro pellets. The company will also show its Econ Pyrolysis furnace for cleaning of extruder and filter components. �

Erema will use the show to launch its new PowerFil business unit, which has been set up to market its proprietary melt filter technology to the wider extrusion sector. The new operation will offer the company’s SW RTF partial surface backflush filter system and Laserfilter – both of which have been recently updated – as individual components for third party extrusion systems. PowerFil is Erema’s response to the increasing demand from recyclers to handle heavily contaminated materials, which the company says its improved Laserfilter model is well suited
to. In terms of performance, the company says the Laserfilter can now be supplied with a continuous filter system offering a 70 micron screen. Filtration has also been improved through rheological optimisation of the support breaker plate, enabling a reduction

in flow resistance and more gentle filtering. Already established in the post-consumer
recycling field, Erema says Laserfilter technology is also drawing interest in PET recycling, where high process stability is essential even at high contami- nation levels. The filter can process input material with more than 1% contamination without difficulty, the company says, while the functional principle avoids dead spaces and makes for short dwell times. This, in turn, helps to prevent “black spots” with PET. Erema adds that the system’s newly developed discharge unit can reduce melt losses by 90% from the 1-2% typical with piston filters. �

Ettlinger Kunststoffmaschinen will introduce a new generation of melt filters that pilot customer trials indicate can yield an up to 28% improvement in throughput with no sacrifice in filtration quality or melt losses in applications such as post-consumer and industrial recycled resin. The company says the new filter design, which it describes as a “landmark” product, uses the rotating, perforated drum principle already employed on its ERF and ECO series. In operation, melt flows continuously through the drum from the outside to the inside while a scraper continuously removes contaminants that are held back on the surface and feeds them to an exit screw or dis- charge shaft. This means the filter can be used fully automatically over periods of weeks or months without interruptions to replace the screen. �
