My TAPPI Story: McKenna Goulette
Experiments were performed on a mixing screw to assess its melting, pumping, and mixing characteristics. This was done by extrusion trials, extrudate sampling, extrusion solidification experiments, and comparison to results for a screw without a mixing section. Comparisons were made as a function of screw speed and color concentrate letdown ratio.
