Press slide granulators designed for extrusion and blow molding.

A line of press slide granulators is custom designed for a variety of extrusion and blow-molding processes. Hosokawa Polymer Systems (Berlin, CT; 860/828-0541) offers a complete set of options for configuring its press slide granulators for use in extrusion and blow-molding processes. The machines are useful in a number of different plastics regrind applications, including extruded profiles, thick and thin sheet, film, and blow-molded bottles. The granulators' options include side-feed chutes for accepting extruded profiles, front-mounted sheet-feed hoppers, roll-feed assemblies for thick sheet and film, venturi systems for sending rejected blow-molded bottles into the granulator, and evacuation systems with blower/cyclone units for continuous volume applications. The four standard granulator sizes offered range from the Model 68, which has a 6 x 8-in. throat size at chamber entrance and a 250 lb/hr throughput, to the Model 1120, which features an 11 x 20-in. throat size and a 460 lb/hr throughput. The granulators stand upright for versatility and convenience. All come standard with a triple-ply laminate for quiet performance. Soundproofed models are available; they reduce noise levels to below 80 dbA.
