High speed Decanter centrifuge


High speed Decanter centrifuge is a solids control equipment that in high rotational speed to separate fine solids after desilter .The decanter centrifuge separate solids material 2-7 microns and plays an important role in solids control equipment to lower mud density and bentonite recovery.

Decanter Centrifuge Processing Theory

The drilling fluid high speed decanting centrifuge power from two motors. Firstly main motor drives the drum and differential shell rotation by the belt . Secondly vice motor drives the spiral through the differential variable speed . Thirdly drum and spiral rotate together in the same direction, but at different speeds .

As well as separating 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.

Apart from high speed decanter centrifuge machine pushing drilling mud onto the inside wall of the drum to pass the impeller. The screw propeller  discharging from the exhaust hole at the small side of the drum. The fluids  from the overflow hole of the large end. So continuous circle like above to achieve the target of continuous solid-liquid separation .

Moreover optimizing the settling zone parameters and feeding mode, enhancing the centrifuge sand removing effect, performance can be comparable to the same specifications of the imported centrifuge .

Furthermore horizontal spiral unloading settlement centrifuge vibration are low noise. By improving high speed the decanter centrifuge rotational part machining accuracy and the dynamic balance accuracy, of the centrifuge vibration and noise to a low level.

As well as production capacity of the single machine is large, compact structure, small occupation.In addition the purification efficiency increased by 30% than original .

High speed variable frequency centrifuge

Aipu decanter centrifuge has the following characteris:
1 Different working speed can be set according to actual need, thus achieving the purpose of energy saving.
2 Fast dynamic responses and accurate speed difference adjustment can greatly improving the content of dry material in the wastes.
3 Switch between speed and torque is quite convenient , which can improve working efficiency.
4 The device can be used to separate solid particles whose diameter is above 2 microns.
5 Explosion-proof electronic control cabinet adopts explosion-proof fan to cooling and heating tape to deice and defrost.

Above all we are specializing in decanter centrifuge  for 15 years .More information please visit my website and my blog.
