ABSTRACT:
A single-rotor cold feed extruder having a barrel and a screw and incorporating a transfermix plasticizing/mixing section is disclosed. The extruder is provided with a fixed set of flow-interrupters/deflectors carried by the barrel and positioned in a circumferential cut in the screw downstream of the transfermix section. The extruder is characterized by radially movable throttle members which are located around the flow interrupters/deflectors so as to provide an increase of throughput for and improved quality of difficult-to-extrude compounds.
