摘要： A screen apparatus includes a tank, a first cylidrical screen disposed inside the tank to form a first chamber, and a second cylidrical screen disposed outside the first cylindrical screen. The second cylindrical screen defines a second′ chamber facing the first cylindrical screen and having upper and lower portions communicating with an inlet portion, and second″ chamber. A connection member has a groove facing the second′ chamber at an intermediate portion of the second cylindrical screen, and a passage communicating with the groove for discharging a paper stock. The paper stock flows to the second′ chamber through the upper and lower portions. A part of the paper stock passing through the first and second cylindrical screens is discharged through first and second selection outlet portions, and a part of the paper stock not passing throught the first and second cylindrical screens is discharged through the passage.

摘要： A screen apparatus for paper making capable of substantially fully recovering fibers from a paper feedstock which has been subject to a pulper and discharging a residue while dehydrating it. A paper feedstock is subject to two-stage maceration and two-stage screening through first and second screen chambers each provided therein with a screen and macerating blade combination. The screens are each cleaned by the macerating blades, so that fiber pieces contained in the paper feedstock are substantially fully recovered with high efficiency and a residue is discharged while being substantially free of fiber pieces and substantially dehydrated.
