SCREEN MEDIA AND A SCREENING PASSAGE THEREFOR |
摘要 |
A screen media (200) for use in screening pulp slurry has a first side (204) and a second side (206). The pulp slurry is fed from the first side of the screen media to the second side of said screen media through a plurality of screening passages (205). Each said screening passage includes a contour cut (210) formed in the first side, a back groove (208) formed in the second sid e, and a residual thickness (234) between the contour cut and the back groove. An elongate slot (235) is formed in the residual material, and the residual thickness has a substantially uniform thickness about the elongate slot. Whe re the slot extends completely through the residual material it defines a throu gh- slit (236) through which slurry flows and is filtered. |
