Abstract: Single conical screw extruder is easier than common extruder in solid-feeding with compression effect, which is capable of processing powder or thermal sensitive materials. On the basis of classic extrusion theory, the conical degree can be analyzed by the developed solid- and melt- transportion models as well as melting model in compression section. Conical geometry is favorable for increasing output while decreasing the length of melting zone.
