Screen system

A method of mounting a screen system in a vibratory screen apparatus comprising the steps of:

• providing a basket having screen system support runners formed and arranged for sliding insertion and removal of the screen system, each one of said support runners provided with at least one clamping device;
• providing a screen element and a support frame having a clamping force receiving face and a frame element engaging face, and wherein at least one of said clamping force receiving face and a frame element engaging face is inclined relative to a principal plane of the screen element;
• inserting the screen element into said basket wherein said support frame is supported in said support runners;
• and
• activating said at least one clamping device so as to clamp said screen element securely together with said support frame to said support runners, whereby said at least one clamping device will concomitantly tension said mesh panel and clamp together said support frame to said support runner.

A method of screening a fluidised particulate material suspended in a liquid medium, said method comprising the steps of:

• a screen element disposed on a support frame, said support frame being provided with spaced apart first and second elongate frame elements including a support face and further elongate frame elements extending between said first and second frame elements for supporting a mesh panel of said screen element, wherein said mesh panel includes first and second elongate support members extending along opposite end portions of said mesh panel, said first and second support members including a clamping force receiving face and a frame element engaging face and wherein at least one of said clamping force receiving face and a frame element engaging face is inclined relative to a principal plane of the screen element, said first and second support members being formed and arranged for secure interengagement with said first and second frame elements with at least one of said first and second support members and said support face being formed and arranged so that when said at least one first and second support member is clamped to said support face of the respective one of said first and second frame elements by said clamping system, said at least one first and second support member is subjected to a force component substantially in the principal plane of said mesh panel, so that said mesh panel is securely held under tension against said further frame elements and said respective one of said first and second frame elements is clamped together with said at least one first and second support member to the basket;
• activating a vibratory unit of said vibratory screen apparatus;
• and
• feeding said fluidised particulate material onto an upper surface of said screen element.
