Abstract: A vibratory screening machine includes replaceable screen assemblies. Compression mechanisms are used to secure replaceable screen assemblies to the vibratory screening machine. Each compression mechanism applies a force to a replaceable screen assembly that includes both a horizontal component and a downward vertical component. Each replaceable screen assembly is typically substantially flat prior to installation on a vibratory screening machine. The force applied to a screen assembly by one or more compression mechanisms causes the screen assembly to be pushed into engagement with underlying concave support members such that the screen assembly itself assumes a concave shape with the center of the screen assembly being lower than the side edges. The vertical downward component of the force helps to secure the screen assembly to the screening machine.

Abstract: A basket system for a shale shaker includes a front, solids discharge end and a rear, feed end, spaced apart by opposed first and second sides. The feed end includes a fluid retaining wall. A first screen deck frame is mounted or mountable to the basket for supporting a screening surface and forming a first screen deck in use. The screening surface of the first screen deck has a lower, feed receiving end that is proximal to the fluid retaining wall at the rear end of the basket and a distal, higher, solids discharge end at the front end of the basket. The basket further includes at least one mounting for mounting at least one additional screen deck frame above or below the first screen deck frame.

Abstract: A screening apparatus includes elongate beams and screen panels mounted to the beams to form a broad screening surface. Each of the panels are mounted so that side edges of adjacent panels are in facing relationship. Each panel is mounted to a pair of beams to bridge between two adjacent beams. The panels are mounted to the beams by fixing members. The fixing members have a pair of upstanding rails that are spaced apart to define a longitudinal gap between them. The panels are mounted to the beams by cooperation between the side edges with a rail of a fixing member. Cover strips extend along the beams and include a cover portion and a locking portion. The cover portion bears against an upper surface of a pair of adjacent panels and the locking portion bears against facing surfaces of the rails to resist movement of the rails towards each other.

Abstract: A screen system for improving a vibrating shaker apparatus for separating drilling fluid and drill cuttings is described. The screen system comprises a dual screen having a coarse mesh upper screen attached to a finer mesh lower screen with a channel between the two screens. One or both of the screens may be wedge shaped to affect the flow rate of drilling fluid and drill cuttings across the screen. The screen systems can be installed in existing shaker apparatuses using various attachment systems, such as wedge clamping systems, hydraulic or air pressure clamping systems, or hook screen systems.

Abstract: An apparatus, a system and a method for reinforcing a screen has a screen rod assembly extending from a first end to a second end. The screen rod assembly encloses an interior. A spring-loaded plunger is located in the interior and adjusts the length of the screen rod assembly. A ball joint is on the screen rod and defines sections of the screen rod assembly that bend around the ball joint to reduce the length of the screen rod. A sleeve extends from a screen with segments separated by a fold line extending along a width of the screen. The sleeve receives the screen rod assembly to reinforce the screen. In an embodiment, a screen pinch assembly is defined where the sleeve engages a retention clasp of a screen tensioning system that receives the screen. The screen pinch assembly holds the screen in place.

Abstract: A system includes a first screen having a first latch on a first end of the first screen, a second screen having a first catch on a first end of the second screen, and a screen adapter that connects the first screen and the second screen. The screen adapter includes an elongate body, a first catch formed on a first side of the elongate body that engages the first latch on the first end of the first screen, and a first latch formed on a second side of the elongate body that engages the first catch on the first end of the second screen. A method includes inserting a first screen into a vibratory separator, inserting a screen adapter into the vibratory separator, coupling the screen adapter to the first screen, inserting a second screen into the vibratory separator, and coupling the second screen to the screen adapter.

Abstract: A screen system having a plurality of screen elements that can be readily removed and replaced to vary one or more characteristics of the screen surface formed by the screen system. The screen system includes a support system for supporting at least one screen element to prevent deformation of the screen element that typically would occur due to the insufficient structural stability of the at least one screen element relative to the weight of the product being screened. Preferably, the support system includes one or more support elements that can be readily and easily installed and removed from the screen system. The support system is preferably configured to permit the one or more support elements to be positioned at different locations in the screen system. Preferably, the support system is configured to permit a variety of different support elements to be used to allow a greater variety of screen elements to be used.
