Priciple of Decanter Centrifuge Separation is Based on the High-speed Rotating Rolle

The mud separation process between solid phase and liquid phase is completed in the roller. 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 is also a important equipment in solids control system. It is widely used in drilling waste. It is used in separating suspension of solid phase with particle diameter≥2μm for drilling mud and fluids handling.

1. It can operate at full speed to finish feeding, centrifugal sedimentation discharge and other procedures, high degree of automation.
2. It optimizes the settling zone parameters and feeding mode, enhances the centrifuge sand removing effect, performance can be comparable to the same specifications of the imported centrifuge.
3. Horizontal spiral unloading settlement centrifuges vibration is low noise. By improving the centrifuge rotational part machining accuracy and the dynamic balance accuracy, the centrifuge vibration and noise can drop to a low level.
4. The machine has large production capability, compact structure, small occupation, and can automatically run. It is convenient to maintain and can be closed operation.
5. Simplified solids control system, low energy consumption, lighter working load, and the purification efficiency increases by 30% than original.
6. It uses the frequency conversion governor, compared with similar products with low energy consumption, working speed is adjustable, etc.

KOSUN oilfield drilling mud decanter centrifuge can meet with different requirements of mud treatment under various drilling condition, that can do sedimentation and separation for particles more than 2 um. After treatment, the mud can achieve ideal viscosity and proportion, results in better recycling, high efficiency, saving and environment protection.
