On the basis of analytical descriptions of mass transport in the feed and dosing zones of single screw extruder the distribution of pressure along the screw pitch has been determined and the phenomenon of pressure pulsation, as measured at defined points of cylinder has been characterized. The causes of pressure pulsation in the extrusion head have been described and the possibilities of counteraction outlined.
