As we know, in solids control system for oil&gas drilling, after the third phase, the desilter, debries bigger than 30 (15-47) microns are cleared out.

Once a client told us that they use mi swaco 414 with tank as a centrifuge system for their diamond drilling, we find we producing the equivalent one, LW220. So after proved with our experenced engineer, then re-researched by the cooperation universities, we manufactured our own centrifuge system for diamond drilling. LW220 with mud tank. Rugged design, compact body, efficient solution.

The differential gear type is mechanical differential, and the treating capactity is ≤ 150lpm, which means the maximun capacity is 150lpm, and you even can use this to handal the drilling mud with about 20lpm.  Other specific is as shown below:

Drum diameter: 220mm

Rotary speed:1500~4800rpm (Variable Speed)

Extruder rate L/D: 4.3

Separation factor: 2800G

Motor power(explosion proof)：main power：11kw；Assistant motor: 5.5kw

Dimension ：2020×1080×755mm

Weight ：1000kg；

Operation period：continuously 24hours

Guarantee for 12 months from date of commissioning or 18 months from date of shipment, whichever comes first. during the guarantee period , our company will be responsible for problems caused by quality of production raw material except the damageable spare parts of decanter centrifuge caused by incorrect man-made operation.

Decanter centrifuge is the fourth class solids control in drilling mud separation system. Decanter centrifuges used to separate more fine particles from drilling cuttings.

GN drilling mud processing system is a complete “closed-loop” re-circulating liquid filtration / fluid clarification system typically applied to glass, ceramic, and metal grinding coolants as well as other industrial fluids.

The main structure and simple principle of GN Decanter centrifuge

The solid wall bowl has a cylindrical section for good separation and clarification of the liquid and a conical section for dewatering the solids. The product enters the decanter through the feed and is led into the separation chamber via the distributor. Under the action of centrifugal force, the solid particles sediment on the bowl wall and are conveyed to the solids discharge by the scroll. On decanter the clarified liquid flows off under gravity whereas on decanter type the liquid is discharged under pressure by means of centripetal pump.

Centrifuges can be customized

Centrifugal filtration equipment By matching the appropriate tank size and capacity requirement, decanter centrifuges are designed and configured to suit each customer’s individual application. GN will size, design, and configure a decanter centrifuge that suits your facility and specific application requirements.

LWF Decanter centrifuges are designed to provide a continuous and consistently low minimum level of suspending solids and extend the life of the working liquid / fluid while providing a low maintenance and environmentally effective method of separating and handling the separated solids / sludge.

More on GN LWF Decanter centrifuge

GN produce qualified decanter centrifuges, high performance and efficient on drilling mud solids control. Separating suspended fine cuttings out from drilling fluids. To make well drilling more cost-effective, and economical cost. Knowing more info on LWF Decanter centrifuges, please contact GN Solids Control freely.
