MELT FILTRATION | MACHINERY
has become one of the most critical customer requirements over the past years, it says. To meet this demand, Nordson BKG last year expanded the availability of the pressure-controlled venting start to all its continuous melt filters. Fimic says it has been working for
many years on improving its filtration technologies to meet growing challenges of recycling post-con- sumer and post-industrial plastics. It is alone in offering five different models of automatic melt filters, covering diverse applications and output requirements. The RAS system, the company’s
flagship product, is a scraping filter known for its flexibility and strength. It has a rotating scraper with two blades and can deal with very high contami- nation levels in post-industrial and post-consumer materials, thanks to the adjustable discharge valve system. The ERA melt filter, which evolved out of RAS, was a response to the need for double filtration in
a single machine with two consecutive filtration chambers using punched or laser screens.
RAS+REF can operate in
scraping mode or in backflush mode, offering an extra option for recyclers wanting to treat materials with mesh screens too. “It is an ideal option for woven mesh processing with excep- tional final results,” says Fimic. The TEN melt filter with automatic screen changer allows continuous filtration on woven mesh, with the addi-
tional option of adjusting the speed of the screen change according to the melt
pressure to guarantee regularity and quality of post-industrial waste, without the need for constant supervision by the operator. Fimic says its GEM model is the largest melt filter
on the market. “GEM combines the power of RAS with the winning idea of the ERA double filter,” it says. It combines two identical screens (600 or 700 mm diameter), two scrapers and two valves, achiev-
