The desander is designed for efficient removal of sand particles from drilling fluids in solids control systems.
It is the second-stage solids control equipment after the shale shaker, mainly used to separate solid particles sized 47-76 microns from drilling mud, improving drilling fluid performance and reducing equipment wear.
The equipment is widely used in oil & gas drilling, HDD drilling and mud recycling systems.

Main Features
High separation efficiency
Effective sand removal performance
Compact structure design
Stable and reliable operation
Reduced equipment wear
Easy maintenance
Long service life
Working Principle
The drilling fluid enters the hydrocyclone through centrifugal pressure.
Under centrifugal force, heavier sand particles are separated and discharged from the bottom outlet, while cleaned drilling fluid flows back into the mud system.
Applications
Widely used in:
Oil & gas drilling
HDD drilling
Water well drilling
CBM drilling
Geothermal drilling
Mud recycling systems
