Abstract: A screen for a vibratory separator includes at least two layers of screening material, at least one layer of screening material made of a plurality of intersecting wires having a coating containing nickel or chromium. Wires in the screening material including first shute wires and first warp wires at a right angles to each other. The first warp wires at a right angle to first shute wires, the second wires including second shute wires and second warp wires, each of the second shute wires at a right angle to second warp wires, and each of the second warp wires at a right angle to second shute wires. The first warp wires are aligned with second warp wires, and each of the first shute wires are aligned with a second shute wire.

Abstract: A screen for a vibratory separator, the screen including at least two layers of screening material, including a first layer and a second layer, the first layer made of a plurality of intersecting first wires, the second layer made of a plurality of intersecting second wires, the first wires including first shute wires and first warp wires, the second wires including second shute wires and second warp wires, certain of the first warp wires aligned with a second warp wire, and/or certain of the first shute wires aligned with a second shute wire.

Abstract: A screen assembly for a vibratory separator, the screen assembly including a first screen assembly, a frame to which is mounted screening material, at least one seal member on the frame for sealing contact against a second screen assembly. A unibody structure for a first screen assembly for a vibratory separator, the unibody structure having an integral body member with a portion having a plurality of spaced-apart openings therethrough defining a pattern of a plurality of spaced-apart screening openings, the integral body member including side portions foldable to form a pair of spaced-apart integral side members, and at least one seal member on the integral body member for sealing contact of the unibody structure with another item.
