Abstract: A screening apparatus includes elongate beams and screen panels mounted to the beams to form a broad screening surface. Each of the panels are mounted so that side edges of adjacent panels are in facing relationship. Each panel is mounted to a pair of beams to bridge between two adjacent beams. The panels are mounted to the beams by fixing members. The fixing members have a pair of upstanding rails that are spaced apart to define a longitudinal gap between them. The panels are mounted to the beams by cooperation between the side edges with a rail of a fixing member. Cover strips extend along the beams and include a cover portion and a locking portion. The cover portion bears against an upper surface of a pair of adjacent panels and the locking portion bears against facing surfaces of the rails to resist movement of the rails towards each other.

Abstract: A screening apparatus includes a plurality of spaced apart parallel beams and a plurality of screen panels mounted to the beams to form a planar screening surface. The panels are mounted to the beams by fixing members that extend in the longitudinal direction of the beams and that engage side edges of the panels. The fixing members have a pair of upstanding, longitudinal rails that are spaced apart to define a longitudinal gap between them and the panels are mounted to the beams by engagement between side edges of each panel with a rail of a fixing member. The side edges of each panel include an overhang that overlies an upper end of each rail and that extends into the gap between the rails. The rails and the overhang include locating gaps to receive a locking member to locate panels relative to the fixing members.

Abstract: A screening apparatus includes a plurality of spaced apart, substantially parallel beams and a plurality of screen panels mounted to the beams to form a planar screening surface. Elongate side walls are provided on opposite sides of the screening apparatus and side edges of edge panels extend in close facing relationship to the side walls. Elongate side clamps are mounted to the side walls and have a bottom edge for bearing against an upper surface of the side edge of the edge panels. The side edges of the edge panels include locating gaps and the side clamps include projections, whereby the projections are received within the locating gaps to locate the edge panels relative to the side clamps against movement of the edge panels lengthwise of the side clamps.

Abstract: A screening apparatus includes beams and screen panels forming a broad screening surface. Each panel is mounted to a pair of beams along opposite side edges to bridge between two adjacent beams. The panels are mounted to an upwardly facing edge of the beams by elongate fixing members extending in the longitudinal direction of the beams. The fixing members engage opposite side edges of the panels and include a pair of projections that extend into openings provided in the edge of the beams. Each projection is engaged by a locking clip to prevent release from the openings. The openings into which the projections extend are of greater diameter than the outside diameter of the projections providing a loose fit within the openings, to allow movement of the fixing rails and the screen panels before the projections are engaged by a locking clip.

Abstract: A shielding device 23, 24, in apparatus 1 for screening ore or like material includes an elongate body portion 25 for location over the top surface 7 of a support beam 3 of a support frame for screen panels 6. The shielding device includes at least one skirt 26 projecting from a side of the body portion 25. The device is locatable between the screen panels 6, a fixing member 13 for the screen panels and the beam 3 and provides a surface 27-27a for collecting fines material that ingresses between the screen panels 6 and fixing member 13 and deflecting it away from the beam 3. Use of the shielding devices reduces wear on the support beams 3 due to the abrasive fines material. The shielding devices are consumable items and can be replaced.

Abstract: A screen panel module for mounting on a screen deck frame for screening, separating and grading materials such as ores. The module comprises a stiff frame component for supporting a resiliently flexible screening surface provided by a panel component. Opposite sides of the panel component include depending flanges having ribs for seating in complementary grooves in sides of the frame component for removably mounting the panel component on the frame component. The module includes means such as ribs, grooves, beads or the like, preferable associated with both the panel and frame components for interengaging with fixing means for locating and fixing the module to a screen deck frame. Whereas the whole of a prior art screen module has to be exchanged when worn, the invention allows the exchange of one component of a module, namely the panel component, which component costs a fraction of the whole module.

Abstract: Screening apparatus for screening, separating or grading materials such as ores or the like includes a screen deck frame (3) which supports at least two adjacent screen panels (2). Each screen panel (2) includes a longitudinally extending arm (20) connected to a side face (19) of the panel by a cantilever section (22). The adjacent screen panels (2) are secured in position by virtue of the arms (20) being clamped between a rail type fixing member (4), which is fixed to the screen deck frame by bolts (9-11), and a rail type retaining member (5). Retaining member 5 has a cover portion (27) that overlies the joint between the adjacent screen panels to prevent the entry of ore fines into the joint. Embodiments are described wherein the arms may extend upwardly or downwardly, and wherein the upper surface of the cover portion of the retaining member may lie flush with the upper surface of the screen panels.

Abstract: A system for fixing screen panels to a screen deck frame of an ore screening apparatus. An elongate fixing rail extends over the screen deck frame along and between side edge regions of a pair of adjacent screen panels. The fixing rail, in use, is non-interconnecting with the screen panels. An elongate retaining strip extends along the fixing rail, and engages the side edge regions of the screen panels in an overlying relationship. The retaining strip is connectable to the fixing rail so that the retaining strip secures the screen panels in position against upward movement away from the screen deck frame.
