KOSUN Water-base/oil-base mud cuttings Equipment VC-2000 Vertical Cuttings Dryer

The Vertical Cuttings Dryer 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 900RPM with G force up to 430. 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.

Water-base/oil-base mud cuttings enter the top hopper of vertical centrifuge and fall onto its internal separation area. The internal cone rotates at a high speed of 900RPM and generates a centrifuge force of 430G. For density difference between liquid and solids, mud is hurled out of surface of drilling cuttings and passes through screens, and solids are retained inside the screens. And then, liquid is discharged from the liquid outlet and dry solids are discharged from the bottom of equipment.

June 3, 2015, KOSUN mechanical VC-2000 Sulige gas field in the oil drilling waste disposal site successful completion of the test, the test results show that the national and industry standards compliance lies, its treated waste water-based drilling mud containing liquid rate ≤4%, to achieve the drilling fluid recycling to maximize impact on the environment is minimized, effectively reducing the emission volume of drilling waste.
