ABSTRACT:
A screen dram for the dewatering and/or washing of cellulose pulp, comprises a first cylinder (2) made from non-stainless material, which is rotatable about its axis (5); a cylindrical screen plate (6) arranged coaxially on the outside of the first cylinder, but at a distance from it, and between the screen plate and the first cylinder an annular chamber (7) which can receive liquid which has passed through the screen plate, which chamber contains passages (26) which extend in the axial direction towards one or both ends of the drum for the withdrawal of the screen liquid. The chamber (7) is lined with stainless steel (8) in the form of one or more cylindrical plate sections (8a, 8b . . . 8n). These, by virtue of shrink joints, can be joined to and bear in seal-tight arrangement against the cylindrical casing of the first cylinder. Preferably, the stainless steel contains at least 5% molybdenum.
