Drilling fluid decanting centrifuge used for recovery barite to remove small solid particles, reduce the mud solid content, to ensure the performance of the drilling fluid. And SiQuan  production drilling fluid centrifuge has high purification efficiency, convenient adjustment and easy maintenance.
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 .
1. Can operate at full speed to finish feeding , centrifugal sedimentation discharge and other procedures , high degree of automation .
2. Optimized the settling zone parameters and feeding mode, enhanced the centrifuge sand removing effect, performance can be comparable to the same specifications of the imported centrifuge .
3. Horizontal spiral unloading settlement centrifuge vibration are low noise. By improving the centrifuge rotational part machining accuracy and the dynamic balance accuracy, of the centrifuge vibration and noise dropped to a low level.
4. The production capacity of the single machine is large, compact structure, small occupation, and can automatically run, convenient maintenance, can be closed operation .
5. Simplified solid control system, low energy consumption , lighter working load, and the purification efficiency increased by 30% than original .
6. Uses the frequency conversion governor, compared with similar products with low energy consumption, working speed is adjustable etc..
