GN main business field is for oil & gas drilling. GN can offer whole line of solids control equipment, but GN can also offer economic separation plant for construction machine. Recently, GN shipped several units of desander separation plant for construction machine. The desander machine can be used for bored pile foundation or TBM as well as the horizontal directional drilling projects.

Working principle of desander separation plant.

1) we match a same flow rate slurry pump. Transferring dirty mud from mud pit to separation plant down deck shaker screen.

2) Generally, we recommend 20mesh screen / 40mesh screen to separate the coarse solids from the dirty mud

3) The fluids will go down to the catch tank.  After that, we design centrifugal pump to transferring the mud to desander cones and separate the above 50microns solids particles.

However, GN main field is oil & gas drilling, as well as HDD drilling. Working principle of GN solids control equipment

1) Shale shaker, the first phase of mud recycling system, removes the particles above 100microns.

2) desander, the second phase of mud recycling system, remove the particles about 40-70microns.

3) desilter, the third phase of mud recycling system, remove the particles about 25-40 microns.

4) vacuum degasser, remove the gas-cut drilling mud.

5) decanter centrifuge, the fourth phase of mud recycling system, remove the particles about 2-5 microns.

6) mud agitator, mud gun, mud mixing unit, mud tanks, centrifugal pumps, are also necessary equipment for mud recycling system.

Except for above equipment, GN can also offer drilling waste management equipment, like waste management vertical cuttings dryer, waste management decanter centrifuge, High G drying shaker,  solidification unit, thermal desorption unit etc. GN can offer turnkey solution for the solids control system & drilling waste management system.
