PLAST 2018 | EVENT REVIEW
sumer materials – containing any type of scrap (metal, wood, paper, textile fibre, sand, and more). It also features zero polymer loss during the cleaning cycle. The Gorillabelt T operates at temperature up to 300°C and pressures of up to 300 bar, with output rates up to 3,000 kg/h. Filtering area is up to 816 cm2

. Screens are on 50m rolls, each sufficient for up to 250 changes. Through a special remote assis- tance module, any process failure can be easily assessed and fixed, as well as control software quickly updated. Cofit says the new unit “is the first step towards an Industry 4.0-ready extrusion project.” A third Italian filtration specialist, BD Plast, showed its latest continuous screen changer, the BDOx3 BF (for Back Flush), for materials with medium levels of contamination. It incorporates a new concept for handling flushing that Dante Boicelli in the company’s commercial department says is quite different from other machines and which he claims has eliminated all blockages in the breaker plates. “We have adopted a completely new concept for the construction of the plate holding the filters,” he said. Movements are controlled pneumatically. The latest melt filter from Ettlinger – a part of
the growing Maag operation since the beginning of this year – “raises throughput to a whole new level for a global customer base,” according to the company. The ERF350 is a further development of the ERF250, which Ettlinger says is its most popular model.
All filters are self-cleaning with a rotating, perfo-
rated drum, through which there is a continuous flow of melt from the outside to the inside. A scraper
removes the contaminants that are held back on the surface and feeds them to the discharge system. This enables the filter to be used fully automatically and without any disruptions over a period of weeks and months without having to replace the screen. The advantages are ultra-low melt losses and good mixing and homogenizing of the melts. Ettlinger ERF filters are suitable for filtering all
standard polyolefins and polystyrenes as well as numerous engineering plastics such as styrene copolymers, TPE and TPU. Foreign particles can be removed from base materials containing up to 18% contaminants. Depending on the type and level of contamination in the melt and the selected screen size, the ERF350 achieves a maximum throughput of over 3,750 kg/hr. That is around 28% more than on an ERF250 using the same filtration surface and with the same footprint. According to Ettlinger Managing Director Volker
Neuber, the ERF high performance melt filters “are a highly efficient way for recycling plants to strengthen their competitiveness in what is a fiercely contested market. Companies which process large quantities profit greatly from our technology.”
