A screen system for screening a mixture of particulate materials includes a support frame configured for receiving a plurality of modular and replaceable screen panels. Each screen panel defines a plurality of apertures that extend along a vertical direction through the screen panel and a plurality of insert recesses that are positioned around the plurality of apertures. One or more ceramic aperture inserts are positioned within the insert recesses such that the screen panel and the ceramic aperture inserts define a screening surface, and wherein each of the plurality of apertures in the screening surface are at least partially defined and surrounded by the ceramic aperture inserts.

An elongate capping is arranged to support cross-tensioned or pre-tensioned screening media at a screen deck. The capping includes a pair of arms to grip a carrier beam of the screen deck and a head attached to the arms via a neck. The head includes flexible widthwise extending flanges that are configured to bend and compress towards the arms to support the screening media when mounted on the head under tension.

System, method and/or apparatus repairs an area of damaged mesh in a sifter screen (80). Such sifter screens (80) have woven wire mesh (81) stretched, tensioned and/or secured over a supporting frame (85) having cells (82). Damage occurs to the mesh (81) over certain cells (82). A plug (10) having a mesh layer (14) inserts and/or locks into place in the damaged cell (89). The mesh layer (14) of the plug (10) is flush with the mesh (81) on the sifting screen (80). Ridges (62) and/or ledges (66) secure the plug (10) in place by engaging a lip (96) in the damaged cell (89) to snap-fit the plug (10) in place.

A multi-deck screening assembly includes upper and lower screen decks, each having first and second deck sections. The upper deck's first deck section has first-size grading apertures, and its second deck section is downstream of the first deck section with second-size grading apertures larger than the first-size apertures. The lower deck's first section has third-size grading apertures and its second section is downstream of its first section with fourth-size grading apertures larger than the third-size apertures. A gap between the lower deck's first and second sections allows oversize material from the lower deck's first section to pass through to a first collection region. A diverter is positioned between the upper and lower decks and over the gap, whereby material from the upper deck collected on the diverter passes onto the lower deck's second section, thereby preventing undersize material that passes through the upper deck from passing directly through the gap.

A screen cloth for use in a screening device for screening out oversize objects, including oil sands lumps and rocks present in an oil sands slurry is provided, comprising at least one screen segment having a top surface and having a plurality of openings therein; and a plurality of anti-wear tiles attached to the top surface of the at least one screen segment by brazing; whereby each anti-wear tile is separated from an adjacent anti-wear tile by a gap that is about 0.5 mm or less such that a brazing material used to attach the anti-wear tiles to the at least one support structure fills the gap between each anti-wear tile through capillary action thereby connecting each anti-wear tile to its adjacent anti-wear tile.

A sleeve and pin combination for fastening of one or more screening media elements to a corresponding attachment socket of a screening equipment, a screening media element for co-operation with the sleeve and pin combination, an arrangement for fastening of one or more screening media elements to corresponding attachment sockets of a screening equipment, and a method for fastening of one or more screening media elements to corresponding attachment sockets of a screening equipment and also a screening equipment for separating solid materials according to size is provided.

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.

Screening members, screening assemblies, methods for fabricating screening members and assemblies and methods for screening materials are provided for vibratory screening machines that incorporate the use of injection molded materials. Use of injection molded screen elements provide, inter alia, for: varying screening surface configurations; fast and relatively simple screen assembly fabrication; and a combination of outstanding screen assembly mechanical and electrical properties, including toughness, wear and chemical resistance. Embodiments of the present invention use a thermoplastic injection molded material.

A scalping insert includes a scalping surface having a plurality of scalping slots therethrough, and a vertical base portion. A shaker screen assembly includes a screen frame having at least one slot, and at least one scalping insert disposed in the at least one slot of the screen frame. A method of processing fluid includes providing a flow of fluid to a shaker screen assembly; and flowing the fluid through a scalping surface and a screen surface of a single shaker screen deck.

A screening apparatus 10, including a plurality of elongate beams 11, a plurality of screen panels 14 mounted to the beams to form a broad screening surface, each of the panels 14 being generally square or rectangular and the panels 14 being mounted adjacent to each other so that facing side edges of adjacent panels 14 are in close facing relationship. Each panel 14 being mounted to a pair of beams 11 along opposite side edges to bridge between two adjacent beams11. The panels 14 being mounted to the beams 11 by elongate fixing members 13 that extend in the longitudinal direction of the beams 11 and that are fixed to an edge of the beams 11 and that engage opposite side edges of the panels 14. The fixing members 13 are fixed to the edges of the beams 11 by projections 24, 25 that are spaced apart longitudinally of the fixing members 13 and that extend into openings 18, 19 provided in the edge of the beams 11. The projections 24, 25 being releasably connected to the openings 18, 19 in the beams 11 and extending out of the openings 18, 19 and into releasable connection with the fixing members 13.
