The Orbital drying shaker is designed for the secondary recovery of drilling fluids that are discharged with the solids from the primary shale shakers. The drying shaker is an effective means of preventing the discharge of oil-wet solids and excess fluids that are contained on or within the solids.
In most applications, the unit has successfully reduced the liquid weight percentage of oil-on-cuttings content to an average less than 14%. The shaker is also supplied with a sump that is able to contain up to 10 bbls (1.6 m³) of recovered fluid. Typically, the recovered fluids are transferred from the sump (via centrifugal pump) to the active mud system for reuse.
