The automatic screenchanger model "3M7" can be used for several applications: compounding, pellets, post-industrial and post-consumer recycling and agricultural film.
The filtering element is a mesh belt available in different sizes and different filtration ranges, up to 80 micron.
It guarantees high regranulate quality at low operating costs and a fully-automatic process.
The system principle lies in its continuity. The new TECNOVA 3M7 guarantees uninterrupted melt flow without any significant pressure peak during screen changings. The material normally flows through a melt channel which has a screen belt filtering impurities.
Anytime the pressure value reaches the set threshold, the screen change process starts, the dirty section is replaced by a clean and fresh one. The whole cycle lasts about 20 seconds.
Some major benefits:
High filter fineness possible, up to 80 micron;
Extruder operation during filter band feed;
Fully automated filtration;
Very low operating costs;
reduction of energy consumption;
almost zero polymer loss during cleaning cycle;
minimize material waste;
reduction of personnel involved;
recycle highly-contaminated plastics;
reduce extrusion system downtimes;
reduction of maintenance interventions;
increase extrusion system throughput and production rates;
24/7 production, with no interruptions or downtimes.
