PELLETISERS | MACHINERY
Pelletising machinery makers are working to deliver optimised yet flexible production systems backed with higher levels of pre- and post-purchase support. Peter Mapleston finds out how
Pelletiser producers respond to new customer demands
Suppliers of pelletising equipment are going the extra distance to give producers of compounds and masterbatches equipment solutions that meet their exact needs. As a result, today’s pelletising systems are being tailored more than ever accord- ing to material type and output levels, while not overlooking the fact that flexibility is still needed in case of changing needs over time. Equipment suppliers are also upping their game in terms of customer service and support, with several players having recently invested in extended testing and trial facilities. Maag can certainly be considered a power- house in pelletising technology, having acquired Gala Industries and Reduction Engineering Scheer in late 2015 to sit alongside Automatik Plastics Machinery, which was previously merged into Maag in 2010. The product line-up now includes underwater and both wet and dry cut strand pelletisers. Maag’s dry cut strand pelletisers are now
branded Automatik Scheer and the latest addition to the equipment line is the SG-M series, which

features integrated mesh filters for quick cleaning and faster material changeovers. The new units also incorporate what Alexander Helm, Product Manager at Maag Automatik, describes as innova- tive HAK (Hot Air Knife) die cleaning technology, which works together with all kinds of Automatik Scheer strand pelletising equipment. “Automatik Scheer strand dies in the SG-M
series provide fast changeovers towards colour changes that will support the potential for complet- ing colour changeovers in 10 to 15 minutes” Helm says. “This is achieved by easy clean pivot design of the die head and a new quick connection system for die plates, which enables an exchange by loosening two socket screws only.” The SG-M die head series is said to be suitable for all kinds of single or twin-screw extruders, including lines running with melt pumps (of which Maag is a major supplier) through an integrated melt adapter connection.
Helm says that even small amounts of fillers such as pigments or glass fibres will almost invariably cause out-gassing and/or create melt residues
