Extrusion International 5-2018

PREVIEW 36 Extrusion International 5/2018 The first half of this year was very positive for Gamma Mecca- nica SpA, an Italian company specialized in the production of lines for the regeneration of plastic materials. The recent events inwhich the company participated at NPE 2018 inOrlando (Flor- ida) and Plast in Milan, proposing as our main topic the new series of GM Tandem regeneration lines, have brought many interesting prospects and confirmed the growing interest in this type of technology. Gamma Meccanica has been operating in the plastic recycling machinery sector since 1987. The Tandem technology has been delivered for many years and recently has been redefined. The most recent systems delivered are the re- sult of continuous technological improvement with a high level of automation, maximumquality of the recycled product (gran- ules) and tremendous energy savings. Thanks to GM Tandem technology it is possible to recycle heav- ily printed, high humidity and highly contaminated plastic ma- terials. The line is composed of a COMPAC unit equipped with the Eco- tronic ® system, a primary extruder, primary screen changer, a connection neck with a special degassing chamber, a secondary extruder and, as an option, a second screen changer for finer fil- tration / purification of themelt and then the pelletizing system. The ECOTRONIC ® system, by increasing the number of revolu- tions above the nominal speed of the motor, allows to control the temperature without adding water and to process materi- als with a high percentage of humidity. Ecotronic guarantees a notable energy savings (up to 40%). An Italian customer has recently installed GM Tandem 160 line for the recycling of milledHDPE. The choice of the customer was determined by the need to recover parts of agricultural plants, in particular irrigation pipes, with high level of contamination from the ground and other residual materials. The material to be recycled is sent to the Tandem regeneration line directly from the washing plant with humidity rate of approximately 8%. Thanks to the patented and innovative degassing system, 10 times more efficient than traditional systems, humidity is ex- pelled directly during the extrusion phase. The double filtration up to 100 microns, guarantees the removal of even the smallest parts of contaminants. The production capacity of this Tandem line and with this type of material is 1200 - 1400 Kg/hr. Another recent case is the GM Tandem 180, purchased by a North American customer for the regeneration of non-woven PP, raffia bags in PP, BOPP heavily printed film and PE film. These are post-consumer and post-industrial wastes with a high rate of contamination like paper, aluminum, PET, PA and sand. In this case the GM Tandem 180 line has the primary extruder of Ø 180 and the secondary extruder of Ø 210. The guaranteed production is 1500 - 1700 kg/hr. Given the success of the Tandem lines and the growing inter- est of recyclers, the company is committed to developing new models. The next line that will be created is GM Tandem 210, composed of two extruders: the first one with Ø 210 and the second extruder of Ø 250, with a production capacity starting from 2000 kg/hr. Gamma Meccanica has always been aware of the importance of recovering such a precious resource as plastic. For this reason, in addition to offering continuous improvement of the per- formances of its lines for the regeneration of plastic materials, together with a group of Italian companies that have been ac- tive for many years on the recycling machinery market, and the European association of plastic recyclers (PRE), it is participating in the project “Are you R”. This projects aim is to raise aware- ness among the European people on the importance of plastic recycling. The goal is to spread the culture of recycling. Through a number of documents, photographs and funny animation films, the project reveals the advantages of plastics and explains how its impact on the environment could be reduced if correct behaviors were maintained. This will be one of the topics of the next “PackagingandRecycling” convention inMilan (26-27 Sep- tember) at which GammaMeccanica is a sponsor.
