This new pastillation machine requires less maintenance

The new Rotoform 4G system is the latest generation of this well-known solution for granulating a wide range of chemical melts, including sulfur, waxes, resins and agrochemicals. The Rotoform family now numbers ten different models, each meeting the needs of a different sector. System enhancements in the 4G include: a redesigned pneumatic re-feed bar, which is raised to the correct operating position at the touch of a button. Automatic positioning of this heated bar ensures that any surplus material left on the depositor is forced back through a channel in the Rotoform, where it is remixed with product and returned to the production process. Another feature is the new bearing unit, which is fitted with enhanced mechanical seals that improve reliability and reduce maintenance work. A significantly reduced “product dead zone” also ensures a lower maintenance requirement, says the company. — Sandvik Process Systems, Fellbach, Germany
