Abstract:
A support for a screen assembly for a vibratory separator, the support comprisinga body with two pairs of opposed sides including a first pair with a first side parallel to a second side and a second pair with a third side parallel to a fourth side, a first series of first holes through the body, each of the first series of first holes having a first opening size as viewed from above, a second series of second holes through the body, each of the second series of second holes having a second opening size as viewed from above, the second series of second holes at a material introduction area of the body and the support positionable in a vibratory separator so that the material introduction area is adjacent a location of material introduction to the vibratory separator, the second opening size smaller than the first opening size, the first series of first holes comprising a plurality of first lines of first holes, the first lines parallel to each other, the first holes of each of the first lines spaced-apart from each other a first distance, the second series of second holes comprising a plurality of second lines of second hoes, the second lines parallel to each other, the second holes of each of the second lines spaced-apart from each other a second distance, and with no first holes interspersed among the second holes, and with no second holes interspersed among the first holes, the plurality of first lines numbering more than the plurality of second lines, and the first lines and the second lines extending across the body from the first side to the second side, the first and the second lines positioned so that material introduced onto the material introduction area of the body can initially encounter the second holes of the second lines.
