Desilter is the 3 phase equipment in drilling fluids cleaning system.
Drilling fluids desilter can be used in oil and gas driiling, in DHH, in mining field. It is usually used after desander. Mostly 4 inch in size. And the desilter cone qty can be choose from 4 ea ~ 20 each. Per different application.
It 4 inch desilter drilling fluids machine can separate driiling solids above 27 microns.
In the model world, it is so much easy to search so many company said they are professional for decantering centrifuge.
As a drilling manager or mud servicer, how to choose the right centrifuge manufacutuer who is really professional for centrifuge manufacturing?
1) Compare their technical datas. To see they can accpet to you or not. If ok, do next steps
2) Ask them for customers reference in your area and your field.Like which drilling company use their centrifuges in U.S.
Ask them how did they sell. Which kind of companies they sell to. Are all new customers? DO they have repeat orders. If they do not dare and can tell you who use their centrifuge. You can continou talking with them.Or, give up.
3) If both ok, and you want further comfirm, visit their factory(GN Solids Control – China top 1 for waste management) and check everything by yourself.
Shale shaker for fine solids separation is a develop trend for drlling rigs.
At present drilling site, more and more mud engineer choise to not match desander / desilter or machine with hydrcyclone. As its performance not stable and difficult for maintenance. You need to change cyclones very office, and every time for change, you need to stop the whole mud system.It incased the drilling cost somehow.
Shale shaker for fine solids separation comes out and welcomed by more and more people. It is shale shaker with very fine shaker screen and good conductance. It can separate even most fine solids in the mud. Relatively, it requirest a higher quality and more reliable performance of the shale shaker.
Verti- G dryer is an advanced machine for treating drilling waste cuttings from OBM and SBM. 
GN verti-G cuttingds dryer can treat OBM or SBM waste cuttings 30~60 tons per hours.
As the most important index for the verti-G dryer performance, GN brand verti-G dryer can reduce OOC (Oil of the cuttings) to 3~5%.
GN Solids team just back from OTC 2013 Huston in U.S.. GN brand vertical cutting dryer and waste centrifuge have wide used in different contries.
As China leading brand, it have a good international name and always competite with U.S brand like Derrick, Swaco, Brandt…
GN Solids took vertical cuttings dryer and high speed centrifuge that indicates GN Solids already been a leader in China manufacutrer for drilling waste management equipment.
