Abstract

An extruder includes an extruder barrel module, an extruder feeder module, a screw motor module, and an electronics module. The extruder barrel module includes an axially extending barrel in which an extruder barrel screw is removably receivable. The extruder feeder module is removably connectable to the extruder barrel module, and has an axially extending flow passage having a feedstock outlet end and a screw motor module mounting end. The screw motor module is removably connectable to the extruder feeder module, and has a motor drivingly connectable with a screw in the flow passage of the extruder feeder module. The electronics module is electrically connectable with the screw motor module and mechanically removably mounted as part of the extruder

Claims (18)

CLAIMS:
