MAAG is presenting solutions for circular economy at Fakuma 2023

Cutting head system with central water injection (CIS)AMN die plates for highest quality requirements are intended for throughputs up to 100 t/h. 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 saber knives, facilitating pellet cooling and ejection.

The underwater pelletizing system PEARLO® 350 EAC is especially designed for high throughputs of like 18.000 kg/h of Virgin Polymer production. The unique cutting blade design and optimum water and material flow conditions within the cutting chamber provide not only ideal and homogeneous cooling 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.

MAAG Ettlinger's ECO 500 high performance melt filterMAAG ETTLINGERs ECO 500 is a high performance melt filter for the filtration of heavily contaminated polymer feedstock. For chemical recycling, this technology 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, ultra-low melt losses constant pressure curve, fast spreading of the contamination and short residence time of the melt in the filter.

MAAGs strand pelletizing system EBG is designed 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.
MAAG Group extrex® gear pumps offer an optimized interaction of the components. Specially developed gear teeth with low compression 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 production consistency and safety.
