Decanter centrifuge is the third phase solid separation equipment of drilling fluid mud system. This week DC Solid control shipped 2 sets of Middle decanter centrifuge to Russian. The model of the Middle centrifuge is DCLW450-1000 Series which is a professional unit used for drilling fluid cleaning system.
The main specification as below:
Drum dia:450mm
Drum length: 1000mm
Treating capacity: 45m3/h
Main Power: 22kw
Back Power: 11kw
The Operation Principle of Drilling Mud Decanter Centrifuge
The drilling fluid decanting centrifuge is driven by two motors. The main motor drives the drum and differential shell rotation by the belt . The vice motor drives the spiral through the differential variable speed . The drum and spiral
rotate together in the same direction, but at different speeds . Separate the solid phases in the drilling mud by the centrifugal sedimentation principle. Suspending fluids is pushed into the rotor drum through the inlet pipe and under
the force of screw propeller, under the effect of centrifugal force, the solid phases will be pushed onto the inside wall of the drum, pass the impeller on the screw propeller and be discharged from the exhaust hole at the small side of
the drum. The fluids is excreted from the overflow hole of the large end. So continuous circle like above to achieve the target of continuous solid-liquid separation.
DCLW decanter centrifuge adopts centrifugal force to separate solid particles out of drilling fluid.Different solid or particle have different density and flow speed,some decanter centrifuge also can separate particles as different size
and density DCLW decanter centrifuge is widely used in oil and gas drilling,chemical,foodstuff,pharmacy,mineral beneficiation,water treatment,etc.
