EREMA Filter Systems for Thermoplastics

As the worldwide leader in manufacturing of plastics recycling equipment Erema has a wealth of experience in filtering polymer melts. Over the years polymer filtration has become one of Erema's key areas of expertise, due to its quality-defining aspects. There are currently more than 2000 Erema polymer filters being used all over the world for numerous different applications to the satisfaction of Erema's customers. As your reliable partner for filtration solutions we offer a wide production program of advanced filter systems, comprehensive advice, prompt service and worldwide support. The Technical Centre at our headquarters in Linz/Austria gives you the opportunity to conduct filtration tests under realistic production conditions.

EREMA Plastic Recycling System with high performance degassing type TVE

Erema TVE extruder design: superior degassing efficiency In various cases (when processing particularly strongly printed, heavily contaminated and/or wet plastic waste) we experienced that conventional degassing extruders do not meet today's requirements in daily recycling practice. This prompted Erema to develop a unique, patented technology: the TVE-extruder design of Erema with melt filter upstream of the extruder venting. The simple yet superior design of this plant combines optimum degassing with finest possible filtration. This rules out the well-known disadvantages of conventional degassing extruders, e.g. limited ability to overcome pressure, sensibility to clogged screens, insufficient degassing, which may even be too low for further processing (particularly in the case of heavily printed or heavily contaminated feeding material). The optional touch screen control enables the recording of production data, operation of plant via control room and on request (via modem) online support through the Erema Technical Centre. The technical features Optimum degassing efficiency: - Contaminants that tend also to form gas downstream of the degassing zone in the case of conventional degassing extruders, are filtered upstream of the degassing zone already. - Any gas inclusions in the melt that are caused by filtered, decomposing contaminants upstream of the filter screens, are removed in the subsequent degassing zone of the extruder. - Only completely molten polymer material can pass through the degassing zone of the extruder. Any unmelted polymer components remain in the section upstream of the melt filter until they are completely molten. Peak pressure rates, which are caused by filters becoming clogged by sudden high concentrations of contaminants, do not adversely affect the degassing efficiency (no risk of melt leakage at the degassing outlets as with conventional degassing extruders). No undesired air pockets in the melt upon screen change, which may be conveyed to the die head. Reduced wear as the contaminants, if any, are already separated in the middle of the extruder. Well proven system, more than 400 delivered worldwide (2004). The economic benefits High-quality, perfectly degassed end product Largely maintenance-free – low service costs Compact, space-saving design Optional touch screen control, which widely increases plant productivity

PC: The Standard EREMA Plastic Recycling System

The advanced EREMA System in its 4th generation from the world leader in plastic recycling equipment. Optional touch screen control enables recording of production data, operation of plant via control room and on demand (via modem) online support through the Erema Technical Centre. Up to 30% increased throughput with lower melt temperature … of processed material with the same extruder size. Now possible due to a considerable change in the ratio between the cutter compactor chamber volume and the extruder size (patented). The enlarged cutter compactor chamber volume provides better precutting, a longer dwell time of the processed material in the chamber and a more even temperature homogenity of the precut, preheated plastic material fed to the extruder screw. Consequently screws are now cut deeper and processing temperatures in the extruder are generally lower. The superb positive result is a considerably lower melt temperature of the processed material, resulting in less heat history and better MFI of the reprocessed material at considerably higher output rates

Plastic Recycling System with integrated single-shaft shredder COAX

The COAX plant design from Erema. The perfect addition to the "classic" Erema system. The COAX plant is ideal as an alternative for the reclaiming of thermoplastic materials which would require separate size prereduction before feeding to smaller classic Erema plants The machine consists of a single-shaft shredder arranged coaxially with an extruder. Both single-shaft shredder and extruder are driven together via only one drive in a straightforward design. This enables direct, discontinuous plant feeding with large-volume material portions which have not been reduced in size such as tangled PP tapes, polyamide fibre bales, PP fibre bales as well as lumps, crates, rolls of film (without paper core) etc.
