At the K 2016, BritAS presents an absolutely new innovation in the matter of melt filtration: The CBMF series – Continuous Belt Melt Filter – is multi-functional and convinces in every aspect by its modular design.
„With the modular design concept, we create completely new possibilities in melt filtration. Because, at buyer’s option, the CBMF can nearly be extended to any dimension – regardless of whether filter area size, combination and type of filter belts. The standard version of the CBMF consists of 2 filter modules but can later also be extended to a triple filter – CBMF 3 - or even to a quadruple filter – CBMF 4“, explains DI Dr. Friedrich Kastner, CEO BritAS, the features of the innovation.
The CBMF is used for filtering efficiently and effectively contaminations out of plastics waste. And that with a constantly high quality of the recycled pellets, whereas the dirt is discharged with a very low loss of melt. BritAS filters are used in the post-consumer sector and for agricultural film waste but also for post-industrial waste and by compounding companies.
From small to large – The sky is the limit
„The advantage for our customers is that they can configure their CBMF along their current requirements and if necessary, the filter can also be extended later. „If two, three, four or more filter heads – the customer decides“, explains Corné Verstraten, CSO BritAS. Also in case of the screen areas, flexibility has priority – at the moment, the areas per module range from 570 cm2 up to 1050 cm2, which at the moment, by the combination of several modules, results in filter areas of 4200 cm² and more.
Flexible filter arrangement – parallel or serial
BritAS ensures the running melt flow via two separately selectable filter chambers, which, depending on the operating status, can be used alternately or parallel. A continuous and fully-automatic operation is guaranteed by the totally new control unit together with the new linear belt take-off including cutting device. As already with the BritAS ABMF, cost-efficient filter belts are used. In future, the spectrum of filter materials for special requirements will constantly be extended.
„Because of the modular design, of course, the arrangement of the filters has to be flexible. That means, the parallel filter assembly is reasonable in order to receive filter areas as large as possible. The arrangement in a line creates the option of multi-level filtration, says Heiko Henss, Plant Manager BritAS.
Extendable components – filter heads & screen belt magazine
Furthermore, additional filter heads can be integrated at any time, since the CBMF can grow together with the customer requirements. The same applies to the belt magazine. Here, one, two, three or more magazines are possible. Depending on the customer requirements, BritAS offers different materials, dimensions, weaves and tensile strength for the screen belts. The filtration fineness ranges from 50 μm to 950 μm.
„We are convinced that our modular design concept is trend-setting for the field of melt filtration and already in the current launch phase, we have received enormous popularity and positive customer feedback“, gladly say Kastner, Verstraten and Henss.
