Abstract: A screen assembly, holding apparatus for it, and a vibratory separator with it, the vibratory separator, in one aspect, for separating components of material introduced thereto, the vibratory separator including a basket, a collection receptacle beneath the basket, a deck on the basket for mounting a screen assembly thereon, the deck having a plurality of deck pins projecting upwardly therefrom, a screen assembly on the deck, the screen assembly including screening material, the screening material having a plurality of openings therethrough suitable for the flow of fluid therethrough, the fluid from the material introduced into the basket, the screening material having a plurality of spaced-apart screen holes therethrough, each screen hole having therein part of one of the deck pins, vibratory apparatus connected to the vibratory separator for vibrating the screen assembly, and holding apparatus for holding the screen assembly on the deck with a part of a deck pin in each screen hole.

Abstract: A screen assembly for mounting on mounting structure of a vibratory separator, the mounting structure having at least one support part, and methods of its use, the screen assembly including a frame with a first frame end, a second frame end and a first side and a second side, at least one crossmember, extending from the first frame end to the second frame end, and spaced-apart from the sides, the frame having a top and a bottom, the at least one crossmember having a top and a bottom positionable above and adjacent a support part of the mounting structure, screening material on the frame, and space maintenance apparatus on the bottom of the at least one crossmember for occupying a space between the crossmember and the support part.

Abstract: A screen assembly, a vibratory separator with such a screen assembly and methods of its use, the screen assembly, in certain aspects, having a frame with a first frame end spaced apart from a second frame end by two opposed spaced-apart sides including a first side and a second side, screening material on the frame, a plurality of crossmembers spaced apart and extending from the first side to the second side, each crossmember of the plurality of crossmembers connected to the first side and the second side, and each crossmember of the plurality of crossmembers having at least one series of openings therethrough; in one particular aspect the frame having crossmembers located to facilitate sealing of the support against screen assembly mounting structure of a vibratory separator; and methods for using such frames and such screen assemblies.

Abstract: A screen assembly for releasable mounting to a mounting structure of a vibratory separator, the mounting structure having a body over which a screen assembly is positionable, part of fluid to be treated by the vibratory separator flowable through the body, at least one upwardly projecting member projecting upwardly from the body, said at least one upwardly projecting member sized and configured so it is receivable in a corresponding C-shaped channel part in the screen assembly, the screen assembly having a support, screening material on the support, at least one C-shaped channel part in the support, said at least one C-shaped channel part sized, configured, and located for receiving said at least one upwardly projecting member of the body of the mounting structure.

Abstract: 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 of a four-sided generally rectangular support 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.

Abstract: A screen assembly, a vibratory separator with such a screen assembly and methods of its use, the screen assembly, in certain aspects, having a frame with a first frame end spaced apart from a second frame end by two opposed spaced-apart sides including a first side and a second side, screening material on the frame, a plurality of crossmembers spaced apart and extending from the first side to the second side, each crossmember of the plurality of crossmembers connected to the first side and the second side, and each crossmember of the plurality of crossmembers having at least one series of openings therethrough; in one particular aspect the frame having crossmembers located to facilitate sealing of the support against screen assembly mounting structure of a vibratory separator; and methods for using such frames and such screen assemblies.

Abstract: A shale shaker system for separating components of drilling fluid with solids entrained therein, the shale shaker system, in at least certain aspects, including a base, a screen mounting basket on the base, vibrating apparatus connected to the screen mounting basket for vibrating the screen mounting basket, the screen mounting basket having mounting structure for at least one screen assembly mounted on the mounting structure, the mounting structure having a body over which the at least one screen assembly is positionable, some components of the drilling fluid to be treated by the shale shaker flowable through the at least one screen assembly and through the body, at least one wear strip attached to the mounting structure, the at least one wear strip having a wear strip body, at least one upwardly projecting member projecting upwardly from the wear strip body, the at least one screen assembly including a screen support with screening material and at least one hole in the support sized, configured, and located
