PROBLEM TO BE SOLVED: To provide a novel screw type extrusion-pelletizer whose power consumption per unit pelletizing speed can be lowered. SOLUTION: In this apparatus which pelletize a material by transferring the material to pelletize in the axial direction while pressurizing the material by a screw 40 and passing the material through a screen installed as to face to the tip part of the screw 40, the screw vanes at the tip part of the screw 40 are made to be multi strips, so that a material A can evenly be supplied and pelletizing load is evenly applied and consequently, the power consumption per unit pelletizing speed can be lowered. |
