Hydrocyclone separators used in solids control, we usually call cones as hydrocyclone also. Under pressure, drilling fluid with solid particles will flow into cones, after high rotation, bigger and heavier particle will be threw to cone wall, then slide down till drop in apex and separated out.

CONE types in complete fluid system

Cones can be divided by the diameters, then including desander cones, desilter cones, as well as the micro cones

For desander cones, we usually treat 6”~12” cones as desander cones. desander cones can separate out 95% drilling cuttings sized over 75 microns and 50% drilling cuttings bigger than 30 microns.

And when the input pressure from centrifugal pump is 0.2MPa, every kind of cones will hold capacity: 20~120m3/h. Desilter hydrocyclone can separate out 95% drilling cuttings sized over 40 microns and 50% drilling cuttings larger than 15 microns. To select proper desilter, desilter capacity should be 1.25~1.5 times of drilling fluids flow

Micro cones hold diameter as 2”. When the input pressure is 0.2MPa, its capacity will be more than 5m3/h. The separation particle size is 7~25 microns
 

Operation and adjustment on CONE

Nowadays, drilling fluids solids control cones are mainly balance cones. If the cone drop in apex is adjusted properly, input pure drilling fluid to it, the fluid will flow through totally from drop in apex, while drilling fluid contains solid flow through it, the solid will flow out of drop in apex. Every solid surface will stick liquid cover, at this time, the drop in apex is called balance point of the cone

To avoid rope type drop down flow, we must make input properly but not overloaded. We should make some adjustment on cones for ideal drop down flow. According adjustment operation on cone the hydrocyclone separator will have ideal performance

In KOSUN, you’ll find desander cones sized 6”, 8”, 10”, 12”; desilter cones sized 4”, 5”; these are common type. For 4” desilter cones, KOSUN replacement ones can be same with Derrick 4” desilter cone. They are interchangeable.
