<p><P>PROBLEM TO BE SOLVED: To improve powdered matter transport performance of a pneumatic transport device by improving processing performance of a discharge damper, in a double damper type continuous-suction pneumatic transport device. <P>SOLUTION: An aeration means 110 for blowing air for powdered matter fluidization is arranged for a second discharge damper 94. Immediately before the second discharge damper is released, a differential pressure between in front of the damper and behind the damper is actively eliminated by utilizing the air for fluidization which is blown in and thus the second discharge damper is allowed to open earlier. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
