A screen panel assembly includes a screen panel and a raised screen component disposed thereon. The raised screen component includes an inclined screen surface that defines a first plane oriented at a first angle relative to the screen panel and a wedge surface positioned at a back side of the raised screen component. The inclined screen surface has a front edge that is aligned with a top surface of the screen panel and is substantially perpendicular to a longitudinal axis of the screen panel, the first plane being substantially perpendicular to a displacement vector along which the screen panel assembly is accelerated by a vibratory separation device. The wedge surface is adapted to disrupt a flow path of a flow of a material mixture flowing in a longitudinal direction across the screen panel by redirecting the flow around opposing sides of the raised screen component.

A shale shaker buffer and wear reduction barrier, placed between a shale shaker filter screen, shale shaker wear items and a shale shaker deck of a shale shaker for the prevention of vibratory and friction-induced wear that is reversibly adhered, placeable and replaceable to a shale shaker filter screen, shale shaker wear items and a shale shaker deck of a shale shaker basket to decrease wear on a shale shaker's functional components, singularly and in combination. The buffer and wear reduction barrier that is the present invention serves the additional function of a solids control barrier as an operable seal between a shale shaker filter screen, wear items and deck of a shale shaker to obviate entrance of solids into mud pits via wear induced areas of separation between shale shaker filter screen, wear items and a deck of a shale shaker.

Systems and methods for separating fluids from drill cuttings. Specifically, the invention relates to shakers that incorporate a vacuum system and methods of operating such systems to effect a high degree of fluid separation. The system and methods are effective across a variety of screen sizes, vacuum flows and vacuum designs.
