摘要:
A method for mounting a screen assembly to a screen mounting structure of a vibratory separator to effectively seal the screen assembly in place, the method in certain aspects including locating the screen assembly on a screen mounting structure of the separator, positioning the screen assembly so that crossmembers (805, 806) of a four-sided generally rectangular support (800) of the screen assembly are either all parallel to or are all transverse to a direction of material flowing across the screen assembly, forcing two sides of the support of the screen assembly down with a crowning apparatus to effect crowning of the screen assembly, the support sufficiently flexible so that two sides thereof other than the two forced-down sides sealingly contact a surface of the screen mounting structure along substantially all of their length.
摘要:
A screen assembly for a vibratory separator, the screen assembly comprising at least one layer of screening material (54a) and a screen support (51) for supporting said screening material, characterised in that, said screen support (51) comprises a multiplicity of trusses and girders (53,54). The invention also relates to a vibratory separator having a screen assembly, of the invention fitted therein for separating solids from a solids laden drilling mud.
