Desilter
Desilter used in well drillings is the drilling mud desilter separator. We also refer it as D-Silt. Desilter is made from desilter hydrocyclone sized 4" usually. Some desilter will be mounted on a bottom shaker or on a mud chute. The bottom shaker can be normal model or mini one.

Description of Desilter
Desilter used in solids control system is the 3rd phase equipment. Desilter is set after desander and prior to decanter centrifuge. The flow rate of desilter separator is decided by cones number. Usually, we utilize 4" cone for desilter. Each 4" cone holds capacity 12~15m³/h. To achieve desilter separation there should be centrifugal pump as cone feeding pump. Under pump transfer power, there will be sufficient pressure pull drilling fluid swirl in cones body. Then solids will be separated out by centrifugal force. Theoretically, desilter will get rid of solids sized over 15 microns
Desilter structure
Including fluid feed inlet, fluid discharge pipe, desilter cones, the support frame, bottom shaker or mud chute. The main parts including hydrocyclone, shaker screen, spring, screen motor, and so on.
Maintenance of desilter
Check the desilter cones regularly to make sure no block on nozzle or Drop in Apex
Make sure sufficient head
Operate desander prior to desilter
When complete well or stop drilling, please brush or clean cones and pipelines to avoid clot
High quality D-Silt manufacturer
There are thousands of manufacturer all over the globe manufacture solids control equipment. Desilter is one small part of such equipment. Famous brand including Derrick, NOV Brandt, M-I SWACO, Aipu solids control, the TSC, and so on
