The new shredder-granulator, “Polyplex” designed, patented and made by Hosokawa Alpine is the latest in our innovative recycling solutions for plastic markets.  Our Polyplex shredder-granulator combines a vertically arranged shredder rotor with a granulator rotor for single-step size reduction. The principle is amazingly unique and revolutionary: The material is fed to the shredder by means of a feed trough and hydraulic ram.  This allows feed material lengths of up to 6 meters. This feed is then shredded and granulated to the perfect regrind size for use or processing.  We use a screen to control the final size which can range from 6 mm on up.  The feed rate is controlled via closed-loop current monitoring to maximize system capacity.  As a result of the combination of shredder and granulator, the comparatively small machine can process, for example, machine purgings of up to several hundred kilos together with profiles, pipes, film, blow-molded parts and many other materials and parts.  In combination with our dedusting systems, the system is compact, extremely efficient and will produce clean, uniform and dust-free regrind.
