Abstract (en)
[origin: CA2364728A1] Pressurized screen to remove contaminants from a contaminant-containing fibrous paper suspension. Pressurized screen includes a housing, a first screen element, essentially axially symmetric and rotatably mounted within housing, and a second screen element, which is essentially axially symmetric. First and second screen elements are successively arranged in suspension flow direction. At least one intake, coupled to housing, supplies suspension to housing, and at least one accepts outlet, coupled to housing, conveys a part of suspension that passes through the second screen element out of housing. At least one coarse reject outlet is located within housing to remove a part of suspension not passing through first scre en element, and at least one fine reject outlet is located within housing to remove a part of suspension not passing through second screen element. First screen elemen t includes conical shape with opening angle (a) between about 10.degree. and 170.degree..
