REGENERATION AND COMPOUNDING

Binova lines with co-rotating twin-screw extruders for post-consumer polyolefins .
The technology of Binova ’ s plants , whose protagonist is the co-rotating twin-screw extruder , is capable of processing post-consumer polyolefin material in the form of ground sheet from a washing plant without the use of a cutter compactor . The material is heated and melted totally under vacuum ; thanks to this process , the creation of “ frost ” is inhibited , guaranteeing a high quality end product . The plant is capable of compounding film production waste with high residual moisture , together with special granule blends . The presence of a high vacuum degassing system distributed over almost the entire length of the extruder cylinder also allows the granulation of highly

achieve 30 percent energy savings with its co-rotating twin-screw ( which has a higher degree of optimization than a traditional single-screw line ),
printed films . Mixing of raw materials takes place directly in the machine ; from this process a perfectly homogeneous material is obtained , and consequently the quality of the final product increases . The plant will be supplied complete with an intermediate material transport and storage station . The production of this technology is totally made in Italy , with special attention
paid to the quality of all components .
THE COMPETITIVENESS OF A SINGLE STEP Being able to do this type of processing in a single pass makes the line very competitive ; Binova offers its Customers something unique , with reduced material handling within the production plant , and proven
reduced energy consumption compared to plants on the market today : for LDPE-based polyolefin materials , consumption will be no more than 0.26 / 0.27 kW / kg while for polypropylene or polystyrene-based materials , such as PP , PS or HIPS , consumption is guaranteed to be around 0.22 / 0.23 kW / kg ( excluding process water cooling ). In a nutshell , Binova manages to
SOFTWARE AND REMOTE CONTROL The line is equipped with software that controls all production , even at high work rates . The system has an automatic OP control panel with Internet connection , which can also be managed remotely . In this way , the technician or production manager can check the status of the line process data , even remotely . Remote control can also be used to perform troubleshooting or fine-tuning in real time .
NEW TRADE SHOWS This year Binova will be exhibiting at the NPE show in Orlando , USA , May 6-10 , 2024 .
