Pelletizing systems: cutting edge technology
Pelletizer manufacturers have been busy developing new products and technologies to meet the evolving requirements of the compounding sector. They include systems designed to reduce energy
consumption and improve process control and quality levels. Other innovations have been introduced to increase the speed of machine start-ups, product changeovers and maintenance operations. In addition, pelletizers are being developed to successfully handle increasingly complex formulations, including high fi ller loadings, high-temperature polymers or sensitive bio-based materials. Over the following pages, we look at the latest
developments and news from a range of suppliers, including Automatik, Bay Plastics Machinery, Berlyn, BKG, Coperion, Davis-Standard, Econ, Gala and Reduction Engineering Scheer.
