According to one aspect there is provided a screen assembly for a vibrating screening machine. The screen assembly comprises a screen chassis and a screen for screening material such as a solution containing liquid and solids. The screen chassis comprises a first face and a second face opposite to the first face, the screen chassis defining a plurality of openings therethrough from the first face to the second face for allowing passage of a material that has been screened. The screen is attached to the first face of the screen chassis and covering the openings of the screen chassis at the first face. The screen chassis may be made of a light-weight, stiff material. The screen may be made of a durable material such as metal. A method for making a screen assembly is also provided.

Embodiments of the present disclosure include a screen basket apparatus includes a substantially vertical cylindrical frame and a synthetic screening surface secured to the frame. The synthetic screening surface may be configured to separate carbon or resin from a slurry of a carbon-in-leach, carbon-in-pulp, resin-in-leach, or resin-in-pulp material as fluid flows from outside to inside the screen basket apparatus such that carbon or resin is retained on an external surface of the synthetic screening surface. The cylindrical frame may be a grid frame and the synthetic screening surface may include a plurality of replaceable screen assemblies attached to the grid frame. The grid frame may include a plurality of openings and each of the plurality of openings is configured to receive a respective one of the plurality of replaceable screen assemblies. The synthetic screening surface may include injected molded thermoplastics, thermoset polyurethanes, and/or other polymeric materials.

A processing system for a slurry material. The system has a vibratory screen disposed atop an open-topped tank. A travel path for a vehicle is disposed directly above the screen and the tank. Slurry material dumped from the vehicle onto the screen is separated at the screen into a particulate-rich stream and a fluid-rich stream. The fluid-rich stream may be pumped to a cleaner so that it may be stored and re-used as drilling fluid. The screen may be a conveyor which removes the particulate-rich stream from above the tank.

A system for separating components from a slurry of drilling fluid and drill cuttings on a shaker screen having an upper side and a lower side within a shaker. The system also has a pressure differential generator to pull an effective volume of air through a section of the shaker screen to enhance the flow of drilling fluid through the section of the shaker screen and the separation of drilling fluid from drill cuttings and further maintain an effective flow of drill cuttings off the shaker. A method of separating components of a slurry of drilling fluids and solids has the steps of delivering the slurry to a shaker, flowing the slurry over a first screen and applying an effective amount of vacuum to a first portion of the first screen to remove the drilling fluids from the slurry without stalling the solids on the first screen.

A modular, pre-tensioned, self-cleaning screening panel having a frame and at least one pre-tensioned wire that is fastened to the frame.

Hydro excavation vacuum apparatus that process spoil material onboard the apparatus by separating water from the cut earthen material are disclosed.

Deck assemblies for vibratory separators are provided. In accordance with an implementation, an upper deck assembly for use with a vibratory separator having a basket and a lower deck, the upper deck assembly includes a pair of side rails, a filter screen, and a support. The side rails are couplable to inward facing surfaces of the basket and the filter screen is supportable by the side rails. The support extends from the filter screen and is configured to engage the lower deck or a support surface of the vibratory separator and provide support for the filter screen across a width thereof.
