Continuous mixing in single screw extruder gear pump systems
Dr. Simon Wachter
The presentation will show developments for continuous mixing in single screw extruder gear pump
combinations supplied by VMI to several industrial customers.
Two possible basic setups allow to build a machine able to adopt to the customers process needs. The
first setting is using a single screw extruder gear pump system with additional feeding by a loss in in
weight feeder via the main hopper.
A second alternative is to side feed compound with an extruder gear pump system into the master batch
of the main machine. Both possibilities are used in different applications which are shown in the
Different ways to judge the quality of the mixing and allowing to set parameters in the right way are
used depending on the process setup and needs.
