<p>A screen apparatus (1) of the invention is provided with a tank (2) for receiving a papermaking material; a screen (3) situated inside the tank (2) for dividing the tank into a first chamber (4) and a second chamber (5) to separate a foreign substance from the papermaking material; a first supply passage (7) for supplying the papermaking material into the tank; a second supply passage (8) for supplying the papermaking material into the tank; a stirring member (10) disposed between an inner wall of the tank (2) and the screen (3) to stir the papermaking material introduced in the first chamber (4); a screened papermaking material discharge passage (20) communicating with the second chamber (5) for discharging a screened papermaking material outside the tank; and a foreign substance discharge passage (30) communicating with the first chamber (4) for discharging a foreign substance outside the tank. The first supply passage (7) includes a first supply inlet (7a) located at an upper side of the tank, and the second supply passage includes a second supply inlet (8a) located lower than the first supply inlet. The papermaking material can be effectively separated by the screen. <IMAGE></p> |
