Abstract
A twin-screw extrusion kneader includes: two rotating shafts provided side by side in an internal space; a rotational driving portion configured to rotationally drive the rotating shafts; and paddles provided in the rotating shafts and configured to rotate along with the rotating shafts so as to knead a kneading material. Further, the twin-screw extrusion kneader includes movable portions provided as members constituting a part of the housing, the part of the housing including an inner wall surface of the housing, the inner wall surface being opposed to radially outer peripheral surfaces of the paddles. The movable portions can be moved in a direction to approach the paddles and in a direction to be distanced from the paddles.
Claims6
A twin-screw extrusion kneader for kneading a kneading material supplied to an internal space of a housing, the twin-screw extrusion kneader comprising:
- two rotating shafts provided side by side in the internal space;
- a rotational driving portion configured to rotationally drive the rotating shafts;
- paddles provided in the rotating shafts and configured to rotate along with the rotating shafts so as to knead the kneading material;
- and
- movable portions provided as members constituting a part of the housing, the part of the housing including an inner wall surface of the housing, the inner wall surface being opposed to radially outer peripheral surfaces of the paddles, wherein
- the movable portions are configured to move in a direction to approach the paddles and in a direction to be distanced from the paddles.
A manufacturing method for an electrode paste by use of a twin-screw extrusion kneader for kneading a kneading material supplied to an internal space of a housing, the manufacturing method comprising:
- manufacturing the electrode paste by the twin-screw extrusion kneader by use of an active material, a binder, and a solvent as the kneading material,
- the twin-screw extrusion kneader used in the manufacturing method including:
- two rotating shafts provided side by side in the internal space;
- a rotational driving portion configured to rotationally drive the rotating shafts;
- paddles provided in the rotating shafts and configured to rotate along with the rotating shafts so as to knead the kneading material;
- and
- movable portions provided as members constituting a part of the housing, the part of the housing including an inner wall surface of the housing, the inner wall surface being opposed to radially outer peripheral surfaces of the paddles, the movable portions being configured to move in a direction to approach the paddles and in a direction to be distanced from the paddles.
