Extruder, operational method thereof, and method of producing honeycomb green body using said extruder

A method of producing a honeycomb body from raw material using an extruder, the extruder comprising:

• at least one screw that extends along an axial direction, the screw including a downstream end positioned downstream in a conveying direction of raw material that is conveyed along the axial direction in accordance with rotation of the screw;
• a housing that houses the screw;
• at least one rectifier plate that axially supports the downstream end of the screw;
• and
• an extrusion die disposed downstream of the rectifier plate in the conveying direction of the raw material, the method comprising:
• conveying the raw material to the extrusion die based on rotation of the screw of the extruder;
• cutting a honeycomb green body being continuously extruded from the extrusion die;
• and
• firing the honeycomb green body obtained by the cutting.

An operational method of an extruder, the method comprising:

• rotating at least one screw that extends in an axial direction and is arranged in a housing of the extruder such that raw material is conveyed along the axial direction;
• axially supporting, by at least one rectifier plate arranged in the housing, a downstream end of the screw positioned downstream in the conveying direction of the raw material;
• and
• rectifying, by the at least one rectifier plate, the raw material conveyed downstream in accordance with the rotation of the screw.
