In general, desilter http://www.kosungroup.com/products/solids-control-equipment/desilter.html is the third stage solid control equipment to treat the drilling fluids. That is a centrifugal device for removing very fine particles, or silt, from drilling fluids to keep the amount of solids in the fluid at the lowest possible point. Usually, the lower the solids content of mud, the faster is the rate of penetration.
A desilter is used to separate silts from drilling muds. The cut point can be as low as 4“. As muds are being used in drilling operations, they are contaminated with silts. In order to use again these muds, it is necessary to separate silts and also to recycle muds to dispose them at the end of work duty.
Desilter is designed by the theory of particle sedimentation. The separation medium-drilling fluid produces some pressure and speed when it passes the centrifugal pump http://www.kosungroup.com/products/solids-control-equipment/centrifugal-pump.html, and flows into the hydrocyclone along the wall, the bigger solid particles along the wall of hydrocyclone sink spirally under the centrifugal force and gravity, and to be discharged from the bottom flow hole and fall on the under micromeshsieve for separation. The other mediums rise along the spiral of hydrocyclone, flow into the fourth class separation equipment-centrifuge for a further cleaning treatment from the overflow hole.
Desilter produced by KOSUN Machinery can be adjusted to control the handling capacity
