Abstract
A mixing section for a feed screw includes a body portion defined along a longitudinal axis. The mixing section further includes a primary flight defining a helical channel, wherein the primary flight is helically wound in a first direction about the longitudinal axis. The primary flight forms a first acute angle with respect to a first plane including the longitudinal axis and defines a cross channel to allow fluid communication between adjacent portions of the helical channel. The cross channel is defined along a second plane such that the second plane forms a second acute angle with respect to the first plane. The first and second acute angles are located in the same quadrant and the second angle is less than the first angle.
