SORTING APPARATUS FOR FRAGMENTED MATERIALS ABSTRACT OF THE DISCLOSURE An improved sorting apparatus for sorting sand, rock, gravel and other fragmented material utilizes a wire screen panel having a plurality of sorting zones with the apertures of each zone having a different cross-sectional area. A multiplicity of equally spaced, parallel, serpentinely crimped longitudinal wires extend from receiving end to discharge end of the panel and are rigidly retained by attachment shrouds at the ends, permitting the longitudinal wires to be tensioned and sagging of the wires avoided by gradually tightening and straightening the longitudinal wires Mounting means is provided to mount the panel in most commercially available vibrating screen boxes and includes a stationary angle iron mountable at one end of the screen box to retain an attachment shroud at an end of the panel and further includes a plurality of clamping devices adjacent the remaining end of the screen box and engaging an attachment shroud at the remaining end of the panel. Each clamping device has a tensioning device attached to the screen box to permit the longitudinal wires to be selectively straightened and tensioned. Im- proved bridging means is provided to bow the intermediate section of the wire screen panel, thereby permitting suf- ficient tensioning of the longitudinal wires and causing them to assume mutually parallel positions, minimizing possible metal fatique of the wires and extending the wear life of panel.
