Decanter centrifuges are specifically built for oilfield applications, both onshore and offshore drilling activities. Adjustable operating parameters enable the decanters to be employed for a wide range of solids control purposes in drilling fluid systems including: Barite recovery from the active mud system or from surplus mud in storage, separation of drilled solids from unweighted muds.

The decanter is equipped with a hydraulic Coupling and belt pulley for main drive and a belt pulley system for the back drive, discharge funnels for solids and liquid discharge as well as a gearbox overload switch, cover open switch and vibration switch.

In most cases Decanter centrifuges do a good job of separation without benefit of chemical additives. However, some fluids containing a high proportion of colloidal fines, e.g. in drilling waste applications, may need to be flocculated to make them separable. Flocculent chemicals are expensive, so it pays to exploit the other tuning capabilities of the Decanter to the full in order to minimize the dosage.
GN solids has varies of choices on decanter centrifuge from top notch material build to economic material build, from big bowl big volume to small bowl small volume, from fixed speed to variable speed.
