The common Hydrocyclone for desander and desilter

The specially designed drilling mud hydrocyclone units are primarily used for removal of sand-size and silt-size particles from returned drilling fluids. DC Machinery resistance polyurethane hydrocyclones are applied to the unit. The unit can be stonealone for use or assembled above our shale shaker through pre-designed connectors. The number of desander and desilter cones is customizable according to the real conditions.

And the commonly used hydrocyclone size are 10" and 4". Following is the detail introduction of the two size hydrocyclones. 

10″ Desander

Sand size solids removal (40 ~ 100 microns)

100% polyurethane hydrocyclone

500 gpm per cone at 75 feet of head

Flexible fast connection is available for user to assemble

Compact design, small footprint

4″ Desilter

Silt-sized solids removal (12 ~ 74 microns)

100% polyurethane hydrocyclone

80 gpm per cone at 75 feet of head

Variable size apex inserts

Available with and without a ramp in the feed inlet

Flexible fast connection is available for user to assemble

Compact design, small footprint

The standalone desander/desilter hydrocyclone unit can be assembled above linear motion shale shaker to recycle the useful drilling fluids from hydrocyclone underflow screening by fine mesh screens. Mud cleaner which combines desander, desilter and dewatering shale shaker in one unit is often used in nowadays drilling applications.
