Abstract
For screening oversized objects and especially long slender particles wherein the long dimension of the particle is aligned in the direction of flow through a fluid-flow conduit, there is provided a screen comprising a pair of opposing corrugated surfaces, the folds or corrugations on the opposing surfaces being substantially parallel, and separated by a distance, and having a wave length, determined by the size particle to be screened. Preferably, the corrugated surfaces are formed as two sets of a plurality of corrugated plates inserted within and extending along the direction of fluid-flow in a conduit, the sets being relatively movable between a position where the two sets are interleaved, and a position where the two are separated.
