Erema, a specialist in plastic recycling systems has announced that it will be launching a new core technology at the K 2013 trade fair. The group is celebrating its 30th anniversary as a business this year. Erema is describing its development as a “new dimension” in plastic recycling system engineering. The presentation will take place during the show.
Erema’s systems are based around a large patented cutter/compactor and extruder combination which can be used for a wide variety of recycling jobs according to the configuration in both inhouse production waste recycling and severely contaminated post-consumer waste applications.
The company launched its first generation of machines in its founding year, 1983. The technology combined a cutter/compactor with a – back then, still radial – extruder, which made it possible to cut, compact and extrude waste plastic in a single, continuous process.
In its second generation machines (from 1993) the extruder was located tangentially to the cutter/compactor. This, Erema claims, enhanced the quality of the end products while increasing output and performance. Additionally, a newly defined scaling of the cutter/compactor in relation to the screw diameter of the extruder connected (patented) made feeding even easier with very large individual portions. Project-oriented modifications to the cutting tools in the cutter/compactor also helped to optimise this process. The longer dwell times in the big cutter/compactor made it possible to direct the material to the extruder with much more homogeneous temperature distribution.
