Drilling Decanter Centrifuge Separation Principle

Drilling decanter centrifuge separation principle is to use high-speed rotating roller driven into the mud in the high speed rotating drum, mud was dumped into the wall to form a liquid circle, solid phased particles of liquid ring get greater than its own gravity for undreds or even thousands of times the effect of centrifugal force, will overcome the resistance of the slurry viscosity to the roller on the inner wall of rapid subsidence formed solid layer, liquid forming liquid layer.

Decanter centrifuge and vertical centrifuge have their own role to play during the oil field drilling process, with decanter centrifuge for drilling mud solids control and vertical centrifuge for drilling waste management. They are used in different drilling stages; however, proper operation of decanter centrifuge and vertical centrifuge can ensure high drilling efficiency, guarantee people and equipment safety and reduce the drilling costs.

The centrifuge may be chosen according to the size and concentration of the strong particles within the suspension liquid or the drilling flare ignition device, density contrast of two liquids, the viscosity of the liquids, the qualities regarding the residue or the sediment, coupled with the separation requirement, at the same time, the requirements concerning the moisture content materials about the residue or the sediment and the clarity of the filtering liquid as well as the separated liquid will be taken into consideration to decide the choice of the centrifuge.
