Vibratory separators and screens
First Claim
1. A device, comprising:
- a panel having a feed end, an exit end, and two laterally spaced-apart sides extending between said feed end and said exit end, said panel comprising;
a plurality of first openings having a first shape and being arranged in a pattern on said panel, said pattern comprising a first group of said first openings that is positioned adjacent to said feed end and two second groups of said first openings that are positioned adjacent to each of a respective one of said two laterally spaced-apart sides, wherein said first group of said first openings extends substantially from said feed end to a first distance from said feed end and at least one of said two second groups of said first openings extends substantially from said first distance to at least a second distance from said feed end that is greater than said first distance; and
a plurality of second openings having a second shape that is different from said first shape, wherein a group of said second openings is positioned between said first group of said first openings and said exit end, and at least some of said second openings comprising said group of said second openings are positioned between each of said two second groups of said first openings.

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.

23. A screen assembly for a vibratory separator, the screen assembly comprising:
-
a panel having a feed end, an exit end, and two laterally spaced-apart sides extending between said feed end and said exit end, wherein a length of at least one of said feed and exit ends defines a width of said panel, said panel comprising; a plurality of first openings having a first shape and being arranged in a pattern on said panel, said pattern comprising a first group of said first openings that is positioned adjacent to said feed end and two second groups of said first openings that are positioned adjacent to each of a respective one of said two laterally spaced-apart sides, wherein said first group of said first openings extends substantially from said feed end to a first distance from said feed end and at least one of said two second groups of said first openings extends substantially from said first distance to a second distance from said feed end that is greater than said first distance, each one of said two second groups of said first openings further extending a third distance from a respective one of said two laterally spaced-apart sides that is less than one-half of said width of said panel; and a plurality of second openings having a second shape that is different than said first shape, wherein a group of said second openings is positioned between said first group of said first openings and said exit end, and at least some of said second openings comprising said group of said second openings are positioned between each of said two second groups of said first openings; at least one layer of screening material positioned above said panel; and a support frame positioned below said panel, wherein said support frame is adapted to support said panel and said at least one layer of screening material. - View Dependent Claims (24, 25, 26, 27, 28, 29)
