Abstract
A process and an apparatus for optimal operation of a high-speed extruder in which a pin-lined barrel section and a Transfermix section, both known per se but separately used, are utilized together in an extruder. The combination of these mixing systems allows in a surprising way an increase in the material throughput of 60% to 100%, with the mixing quality remaining the same and the drive torque being halved. The static extrudate pressure can be further increased by arranging an adjustable restriction device downstream of the extruder screw, thereby permitting a further increase in the output rate.
