As the growing market for drilling waste management http://www.kosun.us/drilling-waste-management/, now KOSUN has developed the vertical centrifuge. In China, KOSUN is the only API-certified company who can provide cutting dryer.The KOSUN Vertical Centrifuge returns and recycles large proportion SBM ( Synthetic Base Mud ) and OBM ( Oil Base Mud ) to the purification system, which in the past was regarded as waste dumped to the surroundings. KOSUN Vertical Centrifuge can lower cutting OOC than 6%, the current discharging limit in many areas of the world, however, our goal is to make it lower than 5%, and even further.

Vertical Centrifuge uses centrifugal force to dry drilled solids in oil or synthetic base fluids. A stainless steel screen bowl traps “wet” solids and accelerates them up 900 RPM. Liquid is forced through the screen bowl openings, while “dry” solids are extracted by the angled flights attached to the cone, which rotate slightly slower than the bowl. Tungsten carbide protects the flights from abrasive solids and ensures long operational life. This aids in maintaining a constant gap between the scroll and screen bowl, which is crucial for proper operation. KOSUN Cutting Dryer has been done with strict balance testing for all major rotary components to minimize vibration & noisy.

VC-1000 series Vertical Cuttings Dryer( Vertical Centrifuge) produced by KOSUN is a type of vertical centrifuge, which can perform solid/liquid separation through centrifugal separation. The vertical cuttings dryer can effectively recover the liquid phase in drilling cuttings, making the solid phase become very dry. It is suitable for water-base mud, oil-base mud and synthetic base mud. By recovering the mud in drilling cuttings, the vertical cuttings dryercan reduce the drilling cost and cut down environmental pollution. With handling capacity of 40-60 T/h, the oil on cuttings (OOC) of drilling cuttings can be reduced to lower than 5% (w/w) after treatment, meeting the international emissions standards and environmental protection requirements. The vertical centrifuge can also be applicable for drilling waste management in onshore and offshore drilling.
