PULP PRODUCTION ARRANGEMENT AND METHOD |
摘要 |
A dewatering roll (10) comprises a roll body (20), a mantle support structure (30) and a mantle (40). The mantle support structure (30) is attached around the roll body (20). The mantle (40) is attached against an outer surface (36) of the mantle support structure (30). The mantle (40) has a plurality of through holes (42) constituting mantle flow paths (44). The mantle support structure (30) presents support flow paths (38) from the outer surface (36) of the mantle support structure (30). The support flow paths (38) are in fluid contact with the mantle flow paths (44). The outer surface (36) of the mantle support structure (30) has a static geometric shape defining an envelope having a smaller radius in vicinity of each axial end ( 15) than in vicinity of a centre (16). Thereby, the inner surface (48) of the mantle (44) assumes the shape of the envelope. |
