Abstract:
The present invention relates to an electrode paste manufacturing system that includes, a twin screw extrusion mixer, a mohno pump that is connected at an inlet thereof to an outlet of the twin screw extrusion mixer, a deaerating tank that is connected to an outlet of the mohno pump, and a vacuum pump that is connected at an inlet thereof to the deaerating tank. The vacuum pump is configured such that a conduit system on the deaerating tank side of an airtight line formed at a contact portion between a rotor and a stator of the mohno pump is a closed system with the airtight line being a boundary.
