Drilling fluids desilter is used as 3rd solids control equipment in
whole mud system. However, we also usually combine desander,
desilter, shaker together as mud cleaner. We call desilter as 4th
purification equipment as well. It is used before centrifuge, after
desander. We feed drilling mud to desilter cone by centrifugal
Drilling fluid after processed by desilter cone hold particles
finer than 15 microns. Then we use decanter centrifuge for further
purification. Similar as APCS desander, the desilter capacity or
flow rate is decided by cones number. Usually, each 4" cone hold
Desilter for well drilling Solids Control System
A desilter is the 4th phase purification equipment in the mud
system. It holds similar principle and operational way as desander.
However, the separation point will be finer. Depends on clients
requirement, it can be set to different numbers hydrocyclone.
Desilter cones are typically 4”, but some client will request 3”,
5” as well. So it is rather flexible on capacity configuration.
Desilter can be fit with the bottom shaker
or not. Or it can be combined with shaker and desander together to
be the mud cleaner. We call desilter as the 3rd phase solids

Features Of APCN Desilter
- 100% Polyurethane(PU) Material for desilter cones with longer using
- Clamp type for easy maintenance.
- Compact design with small footprint.
- Flexible options for 1 or 2,or 3 for different capacities.
- Different size of downstream shale shaker for option.
- Flexible fast connection is available for user friendly assembly.
- Tangentially blended into the cone entry as a narrow rectangle to minimise turbulence in the upper section of the cone, allowing the solids
to move quickly to the cone wall.
