Abstract
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.
