Abstract
A plasticating extruder screw conveyor includes multiple primary flights and corresponding multiple secondary flights defining multiple channels on the screw conveyor arranged about the longitudinal axis of the screw conveyor such that radial components of forces between the screw conveyor and unplasticated material located in the channels are substantially balanced so as to reduce to a minimum any resultant radial force upon the screw conveyor and any concomitant lateral deflection of the screw conveyor, thereby reducing or eliminating excessive vibration, wear or galling of the screw conveyor.
