Gneuss is celebrating 'breaking America' thanks to the runaway success of its new rotary filtration system in South America.
Gneuss' new RSFgenius M is especially designed for highly contaminated materials such as in recycling processes.

Gneuss Rotary Melt Filtration System RSFgenius M.
The company - which has been manufacturing process and pressure constant filtration systems and screen changers for more than 30 years - developed the RSFgenius to be fully-automatic and backflushing RSFgenius. It is these features that have made it the 'number one' choice for many processors when looking for high quality filtration, materials with high contamination levels and/or thermally-sensitive melts.
The new RSFgenius M model can cope with even higher contamination rates thanks to the synchronisation of the drive and back-flushing mechanism. This further optimises the unique self-cleaning technology resulting in a significant increase of screen capacity as well as a reduction of the quantity of material lost through backflushing.
RSFgenius M filtration systems are now running successfully in recycling applications, including two in South America.
At the Brandt in Brazil an RSFgenius M 150 exchanged a slide plate screen changer on a 380 kg/h repelletising line. This extruder processes 100 per cent PP and PE reclaim into pellets for injection moulding.
Before the RSFgenius M was installed, the line could not handle all available materials in order to “minimise” the disruptions caused by frequent screen changes. With the fully-automatic RSFgenius M all incoming materials are now being processed and with no disruptions for screen changes the overall line output has been increased by approx. 1000 kg/day. At the same time, thanks to finer screens the end product quality has been increased.
At Reteplast in Argentina an RSFgenius M 150 replaced a slide plate screen changer on a 400 kg/h repelletising extruder. Here, 100 per cent reclaim, mainly PP, ABS and PE, is processed into pellets, also for injection moulding applications.
Orlando Meza, General Manager of Reteplast, said: "When we chose the Gneuss RSFgenius M 150 Filtration System, we knew we were investing in the growth of our products and services both in quantity and in quality. But we did not realise then how much growth and improvement we would get. The new filtration system reduces the number of steps our material has to go through, and among other benefits, it provides huge waste savings, increased productivity and better filtration quality."
In the past the material had to be washed before the extrusion process in order to separate paper contamination. With the RSFgenius M this extra step is not necessary any more. The melt is now automatically filtered to 250 microns, without any disruptions or disturbances.
The RSFgenius M automatically backflushes the screens 350-500 times, depending on the specific material. The material losses through backflushing are considerably lower than the material losses caused by more than 200 screen changes per day before with the slide plate screen changer. All of this has not only increased the daily output by 30 per cent but also improved the end product quality, making for a very happy customer.
