Speziell Mud Desander And Desilter for Tunnel Shield Project

Tunneling shield machine for driving tunnels in soft ground, especially under rivers or in water-bearing strata. The problem of tunneling under a river had defied the engineering imagination for centuries because of the difficulty of preventing mud and water from seeping in and collapsing the tunnel heading.

In order to make the tunnel shield project works more environmental, so the mud must be processed by professional equipment. DC Solid control manufactured many different type desanders and desilters for tunnel shield project. Capacity from 100GPM to 800GPM. And matched differernt material hydrocyclones.

Desander and desilter can efficiency separate out the 15-75um solid phase from the mud, and we can design it according to the mud property to provide the most reasonable unit. And the common size of the hydrocyclone of desander and desilter is the 10" and 4".

10″ drilling mud desander cone:

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″ drilling mud desilter cone:

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.
