PROBLEM TO BE SOLVED: To reduce construction cost of a multi-component extrusion propulsion system as low as possible, while warranting optimum mixed outcome even for a low miscibile composition. SOLUTION: The extrusion propulsion system operating as a mixing means is equipped with an extruder 12 which can serve a mixing subject, preferably a rubber compound or TPE (thermoplastic elastomer) composition, from sideward; is connected to a volumetrically operating propulsion device 14, preferably a gear pump in the output side of the extruder 12; and lets the served composition passed a volumetrically operating subordinate propulsion device which is similarly formed preferably with the gear pump and whose rotational frequency or propulsion speed can be regulated independently from volumetrically operating propulsion device 14: wherein the extrusion propulsion system is characterized in that; it employs (n-1) sets of volumetric propulsion devices to form n compositions while serving especially the nth composition without measuring, and that the rotational frequency of the extruder 12 can be regulated independently from the propulsion speed and volumetrically operating propulsion device 14.
