ABSTRACT:
A modular deck support framework system employing support tray framework sections for vibrating screens having an essentially rectangular outlined perimeter framework. Each support tray perimeter framework has at least: two opposed side framework members and a square cut cross-angle 50, or notched end angle 62, as a feed end cross framework member; and a square cut flat stock 52 or curved top flat stock 52C as a discharge end cross framework member. Square cut cross-angle 50 is oriented such that square cut cross-angle upper leg 50U is pointing essentially upwards and essentially perpendicular to the flow of particles over support trays, and square cut cross angle lower leg 50L is pointing essentially with the flow of particles over support trays. Notched end angle 62 is oriented similarly whenever employed. Square cut flat stock 52 is oriented such that square cut flat stock short side 52S is essentially parallel with the flow of particles being sorted and square cut flat stock long side 52L is essentially perpendicular with the same flow. Curved top flat stock 52C is oriented similarly whenever employed. Support trays also contain wide seal strip support bar 44, or one or more seal strip supports 30, adjacent to and/or above feed end cross framework members, and/or adjacent to and/or above discharge end cross framework members at seam areas of support tray frameworks for increased strength and/or protection and/or to support screening media edges. Typically fastener holes are present to attach modular support trays to vibrating screen side-walls and to each other as needed.
