What is Barite used for?
Barite is commonly used to add weight to drilling fluid. Barite is of significance to petrophysicists because excess barite can require a correction factor in some well log measurements.
Barite Recycling centrifuge
GNLW452S centrifuge is an ideal choice for barite recycling centrifuge, it has been used in oilfield in Russia and middle east for barite recycling. Its max rotary speed is 2200rpm and max separation factor is 1220.
Barite recycling centrifuge is also called low speed centrifuge. Its separating factor is 500~700. To low-density solids, its separating point is 5~10μm. To high-density solids, its separating point is 4~7μm.
Barite recycling unit
High speed centrifuge’s separating factor is 1200~2100 or so, separating point is 2~5μm, it is usually connected with low speed centrifuge to make up a dual centrifuge system. In the system, barite recycling centrifuge is installed in the first phase, barite separated from it is discharged into mud tank to be recovered, liquid is drained into a surge drum first, and then be sent by a pump to high speed centrifuge; the solid separated from high speed centrifuge will be discharged out of the tank and the liquid is back to recirculation system. GNLW363VFD centrifuge can be also used for barite recycling, you can control the speed to 1500~1800rpm by variable frequency drive control panel, when you need to separate more fine solids, you can adjust the speed to 3200~3500rpm.
Except for barite recycling centrifuge, GN can also design a complete barite recycling unit to recycle barite, it is a kind of expensive material for drilling fluids, so it is worth to use such barite recycling unit.
