Desander
Desander is the second phase solids control equipment to recover drilling fluid, separating drilling cuttings in 45-75μm.
Description
According to diameter of hydrocyclones, it is divided into Desander and Desilter. Usually the cone diameter is more than 6″is called Desander, and used as the second-control equipment in drilling operation. 8 “and 10” cones desander are mostly used to separate solid-phase particle size 45-75μm in the drilling fluids.
Drilling fluid is being feeded into desander cone at the horizontal inlet at pressure, the pressure and weight make solids particles moving beside cone wall and drop down, fluids with fine particles will be pressed on top and overflow away through pipeline.
Most common cone diameter is 10 inch. Cone quantity is decided by treatment capacity request. An underflow shale shaker is optional.
