Abstract: A system and a method separate fluid and solids of a slurry using a cross-flow shaker (10) as part of a solids removal system. The system has a head pipe (12) to impart head pressure to the slurry. An intake pipe (14) is connected to the head pipe (12) to interface between the head pipe (12) and a cross-flow chamber (18). Separating screens (20A-20D) are set into the cross-flow chamber (18) to allow fluid to separate as the slurry flows tangentially across the surface of the separating screens (20A-20D). The cross-flow chamber (18) is vibrated by vibration motors (30). The flow of slurry through the cross-flow chamber (18) is restricted by an orifice (34) in an end cap (32) creating back pressure. The solids and the remaining fluid exit the cross-flow chamber (18) through the orifice (34) in the end cap (32).

Abstract: A shaker separates components of a slurry. The shaker has a screen with a pressure differential applied to the screen to remove a portion of a slurry. The pressure differential across the screen can be toggled or pulsed. Generally, various types of separators are used to separate liquids and solids. For example, oil-field drilling operations use separators with screens to remove solids from a slurry. One type of apparatus used to remove solids from drilling mud is commonly referred to in the industry as a “shale shaker.
