Screening media to screen oversized material includes a main body and a plurality of openings extending through the main body between an upward facing contact face and a downward facing bottom face. A textured pattern is provided at the contact face to provide a roughened surface for the partial entrapment of material fines. Such a configuration protects the screen media from aggressive contact with the material to be screened and provides a bedding layer that is maintained by material-on-material attrition during bulk material flow over the media.

A conveyor belt scraper blade includes a scraper layer supported by a support unit. The support unit has a base and at least two support fingers projecting side-by-side from the base. The fingers are arranged to flex to and from contact with a conveyor belt so as to optimise the lifetime of the scraper and minimise damage to the belt.

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.
