Abstract
A device and system applicable to separating components of a slurry is disclosed. The slurry can be a mixture of drilling fluid and drilling cuttings that can be separated with a separatory screen. A separatory tray can be disposed below an underside of the separatory screen. A pressure differential pan can provide fluid flow to a sump. A pressure differential generator can be located within the pressure differential pan and create a pressure differential between an upper side and a lower side of the separatory screen to enhance the flow of drilling fluid through the separatory screen.
