ABSTRACT:
The present invention provides a screen system (8) suitable for use in a vibratory screen apparatus (1), and comprising: a screen element (11) and a support frame (12) therefor, as well novel screen elements (11) and mesh panels (19) therefor, and the use thereof. The screen element (11) consists essentially of a mesh panel (19) provided with first and second elongate support members (22, 23) extending along opposite end portions of the mesh panel (19). The support frame (12) has spaced apart first second elongate frame elements (13, 14) for engagement with the screen element support members (22, 23) and further elongate frame elements (17, 18) extending there between for supporting the mesh panel (19). The screen element support members (22, 23) and said first and second frame elements (13, 14) are formed and arranged for secure interengagement in use of the screen system, with at least one of said screen element support members and the respective one of said first and second frame elements being formed and arranged so that when clamped together, the mesh panel (19) is securely held under tension against said further frame elements (17, 18).
