Extrusion International 4-2023

32 Extrusion International 4/2023 PLAST 2023 Pump & Filtration Systems, Pelletizing & Pulverizing Systems, Recycling Systems and Digital Solutions at PLAST 2023 At Plast in Milan (September 5-8) MAAG Group shows integrated solutions for the processing of polymers in the recycling process in hall 13, booth B31, in particu- lar the ECO 500 high-performance melt filter from ET - TLINGER. MAAG ETTLINGERs ECO 500 is a high performance melt filter for the filtration of heavily contaminated polymer feedstock. For chemical recycling, this technol- ogy is outstanding for filtering low viscosity polymers. The filter is self-cleaning with a rotating, perforated 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 long periods without having to replace the screen. The advantages: Reliable melt filtration, ul - tra-low melt losses constant pressure curve, fast spread- ing of the contamination and short residence time of the melt in the filter. PEARLO ® 350 EAC with liquid-heated die plate for high capacities: The underwater pelletizing sys- tem PEARLO ® 350 EAC is especially designed for high throughputs of like 18.000 kg/h of Virgin Polymer pro- duction. The unique cutting blade design and optimum water and material flow conditions within the cutting chamber provide not only ideal and homogeneous cool- ing effects but also outstanding pellet quality. Another innovative design feature of the PEARLO is the cutting blade advance system, which permits axial movement of the cutter shaft resulting in a precise blade advance as well as a regrinding of the blades during production. This allows higher equipment availability, elongated production runs and thus saves costs. Under the name EBG, MAAG is presenting a strand pel- letizing system for highly filled, hydroscopic and water- sensitive compounds. EBG scores with a high degree of automation, gentle material processing and excellent product quality. From the die head to the granulator, the pelletizing system forms a unit that, despite its compact design, has features of a large compounding system. Au- tomatic feeding in case of strand breaks, removal of melt residues on the die plate by the patented Hot-Air-Knife and synchronization between conveyor belt and strand granulator to name a few. Also, in this machine the con- trol system has been revised and now allows the opera- tor to read out the machine status live via Bluetooth. All MAAG Group extrex ® gear pumps in x6 class de- sign are completely re-engineered and have redesigned components, from the shafts through to the bearings and seals, and optimized the interaction of the compo- nents. Specially developed gear teethwith low compres- sion allow very high pressures to be achieved with low shear rates. The result is a further increase in achievable product quality, volumetric efficiency, as well as produc - tion consistency and safety.
