Decanter centrifuges are used in industrial applications for the continuous separation of solids from liquids where the volume of solids is relatively high.The decanter centrifugal force by solid phase particles of liquid ring and the ratio of its own gravity called decanter centrifuge separation factors, the larger decanter centrifuge separation factor can separat finer particles from the mud.
The centrifuge comprises a rotating assembly driven by a large electric motor mounted in a secure foundation frame, bolted to the ground through vibration dampers. The rotating assembly itself has two main components: the outer bowl and a screw conveyor. When the centrifuge is run up to operating speed the main drive motor turns the outer bowl at typically 3,000 r.p.m. A secondary motor is connected to the screw conveyor , the scroll, via cyclo-gearbox. The produces a differential speed between the outer bowl and the scroll of between 10 and 20 r.p.m. and has the effect of providing a conveying action inside the rotating assembly.
KOSUN DC series drilling decanter centrifuge is used in separating suspension of solids phase with particle diameter(d≥2μm) for drilling mud and fluids handling. Ruggedly built for oilfield and industrial services, it is especially effective in environmentally sensitive areas. The decanting centrifuge delivers high fluid-recovery rates and efficient solids control to significantly reduce the costs of makeup fluids and disposal. The drilling centrifuge must test the dynamic balance for smooth operation over long periods.Speed ranging from 0 to 3900 RPM, generating centrifugal forces reach up to 3000G.
To meet the requirements of the development of modern drilling engineering, KOSUN developed and equipped with the explosion-proof variable frequency control system which could adjust separation factor and drum rotational speed. By this new technology, make the drilling centrifuge adapt property changing of mud during the operation process, which makes the treatment more effective and perfect.
