New Frontier for Single Screw R&D: Mixing & Melting by Extensional Shear
Extensional shear generally has been associated only with twin-screw extruders. However, I am now convinced it can be done with a single moving force (screw) by changing the geometry of the flow field perpendicular to the direction of flow. More (+)

OVERVIEW:
Single-Screw Compounding

Once the workhorse of compounding, single screws were supplanted by multiple screw machines because of the latter’s advantage to perform dispersive mixing. However, new screw designs and mixing elements are regularly being developed to extend the range of single-screw machines.
