GN Desander and Desilter Centrifuge for China Drilling Company

Recently one unit of desander desilter centrifuge is ready for shipment to China drilling company.


GN Desander and Desilter Centrifuge is an efficient solids liquid separation equipment mainly used to remove solid particles such as sand and mud in drilling fluids. It is a specially designed big bowl decanter centrifuge, which separates solid particles from drilling fluid under centrifugal force through components such as a rotating bowl and a screw propeller, and discharged from solids discharge port and fluids distribution port. The Desander and Desilter Centrifuge has the advantages of wide separation particle size range, large treating capacity, compact structure, and simple operation. It can be used to replace the desander desilter mud cleaner more efficiently, with higher separation efficiency and better quality of recovered drilling fluids. The desander and desilter centrifuge has a wide range of application prospects in fields such as oil drilling, which can effectively improve the solids control quality and drilling efficiency of drilling fluids, and reduce the drilling costs.


GN decanter centrifuge applications including oil and gas drilling solids control system, drilling waste management system, oil sludge treatment plant, HDD mud recycling unit, Mining tailing slurry dewatering, TBM slurry separation, construction engineering mud treatment, mining slurry separation and other mud treatment. GN can provide CNEX, IEC EX, ATEX explosion proof motor and control panel for your option. The bowl and screw propeller rotate in the same direction with a certain differential speed, under the centrifugal force, solid phase is dropped on the bowl wall to form sediment layer, then push to the cone section and discharge through the solids discharge port.
Except for desanding desilting centrifuge, GN solids control also produce linear motion shale shaker, mud cleaner, vacuum degasser, 3 phase decanter centrifuge, vertical cuttings dryer, screw conveyor, centrifugal pump, mud agitator, mud tank system, etc solids control equipments. If you need a desanding desilting separation equipment, pls contact with GN solids sales.

Mini Desander and Desilter for Africa Drilling Company

Recently one batch of mini desander and mini desilter are ready for shipment to Africa drilling company. The technical configuration is as below:


The mini desander unit consists of 2ea 10 inch desander cone and mini bottom shaker drived by explosion proof vibration motor. GN own produced composite material frame shaker screen are produced comply with API RP13C standard. The mini desilter cone consists of 16ea 4 inch desilter cone with mini bottom shaker.
Generally, the combination of hydrocyclones above 6 ″is called desander, which is a secondary solid control equipment in drilling operations. 10”and 12”cones are commonly used to separate the particle size of drilling fluid from 44-74μm solid particles.
Compared with the desander and desilter without bottom shaker, the mini desander unit and mini desilter unit with bottom shaker can recycle more drilling fluids and dry the drilling cuttings, it can be installed after primary shale shaker on the solids control system.


Except for mini desander unit and mini desilter unit, GN also produce desander, desilter and bottom shaker 3 in 1 mud cleaner. By use different qty desander cone and desilter cone, the mud cleaner with 500gpm, 1000 gpm, 1500gpm treating capacity.
Features of GN mini desander, mini desilter, mud cleaners are as below:
1. Composite material frame screen and wedge type screen pressing device are applied for fast screen replacement.
2. International brand vibration motor , Martin motor or OLI motor is adopted.
3. International famous brand electrical components, Siemens or Schneider components.
4. The shaker deck bottom with a patented sealing design, with good sealing effect, long service life and easy replacement.
5. The shaker deck angle is adjustable mechanically synchronously, which is convenient and reliable.
