Continuous screen changer Nello/3M7

beltautomatic

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.
