Using this approach it is possible to evaluate the velocity and the stress fields.

Single-screw extrusion technology has been reviewed in the monographs of Schenkel 37 and Herrmann.

A complete and generalized theory for the mixing characteristics of internal mixers is yet to be developed.

the strain across the flow.

The metering zone should be rather shallow to sufficiently homogenize the melt temperature.

Recent studies of the mixing in single screw extruders have considered the mixing of polymer and masterbatch granules see Figure 11.

Each component is metered in the correct ratio to the total extrusion rate.

There is, for example, almost nothing in common between the single screw extruders just after the Second World War e.

This design of twin-screw extruder is also capable of providing good homogenization of the reactants and sufficiently large free volume for precise adjustment of residence time as needed for the reaction [41].
