Vertical Centrifuge is a highspeed vertical dryer that achieves maximum liquids/solids separation in largevolume processing. Vertical cutting dryer gives operators a critical advantage in meeting increasingly stringent environmental regulations for onshore and offshore drilling waste management disposal. Vertical cutting dryer is also called vertical cutting dryer, it is an innovative design which fits for oil-based drilling waste management. Drilling cuttings from the primary solids control equipment like shale shakers or mud cleaners are picked up by auger ( screw ) conveyor and transfered to feeder of the vertical cutting dryer.
KOSUN 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.
The KOSUN Vertical Centrifuge returns and recycles large percentages of SBM ( Synthetic Base Mud ) and OBM ( Oil Base Mud ) to an active system which in the past was lost as waste products to the environment. KOSUN VERTI-G cuttings dryer can reduce total discharged OOC below 5%, which is currently the discharge limit in many areas of the world, our goal is 3.5% total OBM discharge to the environment, and even further.
