Decanter Centrifuge of Mud Treatment System

6. Decanter Centrifuge

Decanter Centrifuge  Decanter-Centrifuge


Decanter Centrifuge separate the suspending fluids using  the principle of centrifugal action, the suspending fluids is pushed into the rotor drum through the inlet pipe and the fluid hole of the spiral feeder.

Under the influence of centrifugal force, solid phase particles are pushed to the internal wall of the drum, then to the nud export of the small end of the drum and excreted. But the fluids is excreted from the overflow hole of the large end.

Such cycle is in order to achieve the purpose of continuous separation.High speed decanting centrifuge are effective for separation.


Drive Principle Mud passing through the Desilter contained in separating fine Cutting
Drive Effect Mud is included in order to reuse as reproducing Barite
Component Bowl, Conveyor, Tube etc.
