Screen panels

摘要

The invention concerns a screen panel (100) for use in vibratory screening operations. The screen panel has a rectangular bounding frame (102) and a screening surface (104) within the frame. The screening surface is formed by elongate, generally parallel, flexible screen elements (106) which are of zigzag shape in plan and which span across the frame. The zigzags of adjacent elements are out of phase with one another, and opposing zags (106.3) of adjacent elements are narrowly separated. The configuration is such that adjacent screen elements define diagonally spaced, generally rectangular screen apertures (108). The zags present generally flat, opposing surfaces (106.4).

主权项

1. A screen panel having a rectangular frame, a screening surface within the frame comprising a plurality of elongate, generally parallel, flexible screen elements which are of zigzag shape in plan and span across the frame, the zigzags of adjacent elements being out of phase with one another with opposing zags of adjacent elements being narrowly separated, whereby adjacent screen elements define diagonally spaced screen apertures between themselves, the opposing zags presenting generally flat, opposing surfaces the opposing surfaces being arranged to abut to limit the extent to which adjacent elements can be deflected apart from one another in a direction transverse to the opposing surfaces.
