At an upcoming event in Milan, Italy, the Maag Group will showcase integrated solutions for the processing of polymers in the recycling process, in particular the ERF high-performance melt filters from Ettlinger.

Maag Ettlingers 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, states the company.

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, adds the firm.

Another innovative design feature of the system 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, mentions the company.

Innovation in strand pelletizing: The Primo Plus Flex provides

  • Shortest unguided length in combination with an enlarged rotor diameter leads 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, this solution is ideal for a reliable dry cut strand pelletizing process, opines the firm.

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, shares the company.

Another innovation in the market is the Maag Brain. This stand-alone monitoring system 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, concludes the firm.
