A screening machine includes wall members, screen assembly guide members, a screen assembly and a compression assembly. The screen assembly includes a frame with a plurality of side members and a screen supported by the frame. The compression assembly is attached to at least one wall member and forms the screen assembly into a concave shape.

A wire screening for classifying material. The screening may include a plurality of interwoven warp and weft wires where the weft wires are individually coated with a coating that expands and collapses to enhance performance and longevity of the screen. The coating of one or more weft wires may differ in at least one characteristic from the coating of one or more other weft wires. The warp wires can be individually coated to enhance performance and/or longevity of the screening. Binding blocks can be used in place of weft wires. The coating of one or more warp wires may differ in at least one characteristic from the coating of one or more other warp wires and/or one or more weft wires. The screening can include a plurality of uncoated weft and warp wires where the crimp depth of each wire forming each opening has a different crimp depth.

A deck (10) for a screening machine comprising: a plurality of screen mats (14a, 14b, . . . 14n) arranged to define a screen channel (12) for screening a material; a support framework comprising a plurality of transverse members (18a, 18b), each transverse member (18a, 18b) comprising an edge retention channel (22) within which an edge portion (24, 26) of at least one screen mat is received; a rigid retention member (28) which is received within the edge retention channel (22) so as to clamp the edge portion (24, 26) in place, wherein the retention member (28) is attached to the transverse member (18a. 18b) by at least one attachment.

A sand cleaning vehicle including a debris collection mechanism that collects debris from sand, a storage compartment that stores the collected debris, a capture device that captures at least one image of the collected debris, a memory storing a computer program, and a processor that executes the computer program. The computer program categorizes the collected debris into a plurality of different debris types using at least one image of the collected debris.

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.

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.
