Broadly diversified global solutions provider of pump and filtration systems, pelletizing and pulverizing systems, recycling systems and digital solutions, Maag Group at Greenplast in Milan (Italy), from May 3 to 6, 2022, shows (hall 14, booth 31) integrated solutions for the processing of polymers in the recycling process, in particular the ERF high-performance melt filters from Ettlinger (a group company).
ERF 350 is a high-performance melt filter for the filtration of heavily contaminated polymer feedstock. 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 and good mixing and homogenizing of the melts.
As for pelletizing, the underwater 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.
For the innovation in strand pelletizing, the company proposes the Primo Plus Flex, which provides: shortest unguided length in combination with an enlarged rotor diameter lead to more torque on one hand and to superior pellet quality on the other; throughputs up to 5,000 kg/h; profitable production due to very high machine availability with wear resistant cutting tools. For applications such as pelletizing of base polymers, recycling products, processing of highly filled compounds or ETPs at different pellet lengths from micro to LGF, the Primo Plus is our first choice for a reliable dry cut strand pelletizing process.
All Maag Group extrex gear pumps in x6 class design are completely re-engineered and have redesigned components, from the shafts through to the bearings and seals, and optimized the 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.
Claudio Bonafede, General Manager, states: “Another innovation in the market is the Maag Brain. We are happy to present this stand-alone monitoring system, which is a step forward in the world of Industry 4.0 and Internet of Things (IoT). The system has been developed to monitor pumps and ensure their maximum efficiency during the operation.”
