Maag Group, Pelletising systems, melt filter & gear pumps from Switzerland
Maag Group is a broadly diversified global solutions provider of pump & filtration systems, pelletising & pulverising systems, recycling systems and digital solutions. More and more new developments in plastics are being made in China, one of the strongest growth markets in the world. Maag Group takes this into account and will be present at Chinaplas in Shanghai, with a booth of over 120 m2 in hall 2.1, booth F82.
Pearlo 350 EAC with liquid-heated die plate for high capacities: The underwater pelletising system Pearlo 350 EAC is especially designed for high throughputs of like 18,000 kg/h of virgin polymer production. The cutting blade design and optimum water and material flow conditions within the cutting chamber provide a homogeneous cooling effect which results in a high 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. This allows higher equipment availability, elongated production runs and thus saves costs.
Maag Ettlinger is presenting the ERF 350, 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.
Strand pelletising: the Primo Plus Flex which will also be on display is claimed to provide
- Short unguided length in combination with an enlarged rotor diameter;
- Throughputs up to 5,000 kg/h;
- Profitable production due to high machine availability with wear resistant cutting tools.
For applications such as pelletising of base polymers, recycling products, processing of highly filled compounds or ETPs at different pellet lengths from micro to LGF, the Primo Plus enables a reliable dry cut strand pelletising process.
All Maag Group extrex gear pumps in x 6 class design are completely re-engineered and have redesigned components, from the shafts through to the bearings and seals, and optimised the interaction of the components. Specially developed gear teeth with low compression allow high pressures to be achieved with low shear rates.
