How to recycle barite from drilling fluids

As an expensive and significant material for drilling fluids, it is necessary to recover it from the used drilling fluids. Usually we use barite recovery centrifuge to recycle barite, together with a high speed centrifuge as a barite recovery unit.

Contaminants in barite, such as cement, siderite, pyrrhotite, gypsum and anhydrite, can cause problems in certain mud systems and should be evaluated in any quality assurance program for drilling-mud additives.

For GNLW363VFD decanter centrifuge, when control the speed 1500~1800rpm, it can be used for recycling barite.
