M. Mahlke et al., CONTROL OF DIRECT EXTRUSION SYSTEMS WITH TWIN-SCREW EXTRUDERS AND GEAR PUMPS - GEAR PUMP, Kunststoffe, Plast Europe, 85(1), 1995, pp. 33
In many extrusion lines today, melt pumps are state-of-the-art technol
ogy The combination of a co-rotating twin-screw extruder, operating pa
rtly filled, with a gear pump makes it particularly difficult to desig
n a suitable control system for linking the plant components. A specif
ic solution to this problem has recently been developed and is present
ed here.
