  • Patent number: 8025153
    Abstract: A screening panel 10 comprises a peripheral frame 12 consisting of a pair of mutually laterally spaced side members 14, 16, which are integral with a pair of mutually axially spaced end members 18, 20. The side members 14, 16 and end members 18, 20 define corners of the panel 22.1, 22.2, 22.3 and 22.4 and the peripheral frame 12 where they meet. A plurality of mutually spaced ribs 15 extend across the periphery of the panel 10 to define a screening surface. The side members and end members are rectangular in cross-section, thereby defining substantially flat upper peripheral surfaces 12.1, outer peripheral surface 12.2 and lower peripheral surface 12.3 of the peripheral frame 12 and thus also the panel 10. The panel 10 includes locating recesses 24 provided at or near to the corners 22.1, 22.2, 22.3 and 22.4 of the panel 10. The panel 10 also has separate securing recesses in the form of semi-circular grooves 30 formed in the lower surface 12.

  • Publication number: 20030012833
    Abstract: A screening element 10 for screening particulate materials such as mineral ores of all types, shapes are a densities, as well as difficult to screen cloggy, and slabby materials. The screening element 10 has a screening surface 12 formed by a plurality of elongate zig-zagged shaped ribs 14. The ribs 14 are resiliently deformable and extend within the periphery of the element 10 in a chevron pattern across the element 10. The ribs 14 are spaced from each other to define between them rows of square screening apertures 22. The screening apertures 22 have sides 22.1 which are orlentated transversely at 90° to an axis 10.1 of the screening element 10; and sides 22.2 which are substantially aligned with the axis 10.1. The element 10 is divided into two rectangularly shaped portions 16, 18 by a centrally disposed straight rib 20. The ribs 14 extend, in the portion 16, at an angle A of approximately 315° to the axis 10.1; and in the portion 18, at an angle B of approximately 45° to the axis 10.1.

  • Patent number: 5938042
    Abstract: A screening arrangement support frame component in which a pair of complementary elongate component members have body portions and cavity defining formations. The component members are secured side by side to one another such that the body portions abut and the cavity defining formations register to form a plurality of cavities for receiving socket elements. A plurality of socket elements, each defining a socket for receiving a protrusion that secures a screening panel to the component, the socket elements being mounted in the cavities when the component members are secured to one another. The thickness of each support frame component at the locations where the body portions abut is smaller than the cross-sectional dimension of the socket elements mounted in the cavities.
