Solutions for advancing circular economy and polymer processing
Maag – hall A6 booth 6202
Maag Group will present solutions that are intended to enhance the circular economy. The AMN die plates for throughputs up to 100 t/h are specifically designed to produce high MI or complex polymers, the CIS system increases the water flow locally to facilitate cutting, improve pellet quality and reduce cavitation phenomena. Easily plugged on existing installations, the additional water flow is then efficiently distributed thanks to the knife holder equipped with a cone and sabre knives, facilitating pellet cooling and ejection.
Maag Ettlinger’s Eco 500 is a high performance melt filter for the filtration of heavily contaminated polymer feedstock. For chemical recycling, this technology is suitable 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, ultra-low melt losses constant pressure curve, fast spreading of the contamination and short residence time of the melt in the filter.
The underwater pelletising system Pearlo 350 EAC is designed for high throughputs of up to 18,000 kg/h of virgin polymer production. The unique cutting blade design and optimum water and material flow conditions within the cutting chamber are claimed to provide homogeneous cooling effects and good pellet quality. Another 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, says Maag. This allows high equipment availability, elongated production runs and thus saves costs.
Maag’s strand pelletising system EBG is designed for highly filled, hydroscopic and water-sensitive compounds. EBG is claimed to offer a high degree of automation, gentle material processing and good product quality. From the die head to the granulator, the pelletising system forms a unit that, despite its compact design, has features of a large compounding system.
Maag Group Extrex gear pumps offer an optimised interaction of the components. Specially developed gear teeth with low compression allow high pressures to be achieved with low shear rates. The company says that this results in product quality, volumetric efficiency, as well as production consistency and safety.
