Cure Feeder Problems in Twin-Screw Compounding : Plastics ...

May 01, 2004· If the screw speed of the side-feeder is reduced to the point where the screws are flooded, then only the speed of the side-feeder screws determines the feed rate into the extruder. So the side-feeder screws should run at a speed that keeps a constant level of material covering the screws—i.e., when they are flooded.

Optimize Feeding to Get More Money in Twin-Screw Compounding

Mar 27, 2017· For twin-screw extrusion processes, limitations can exist anywhere from the feed system through the process section to the downstream equipment. For example, difficult-to-handle materials may stick or flow poorly through feeding equipment, limiting the rate at which they can be discharged into the twin-screw extruder.
