Grooved feed extrusion presentation
WebThe optimal extrusion equipment for HMW-HDPE is a grooved feed extruder. The grooved feed section ensures a positive “bite” of the solid pellet against a barrel wall and prevents this non-tacky material from rolling around on itself. This is the entire theory behind a grooved feed system. To ensure optimal bite and provide consistent http://www.agrojournal.org/26/02-33.pdf
