High-speed VERTI-G Cuttings Dryer Used in Liquids/solids Separation

The vertical centrifuge from KOSUN incorporates a high-speed VERTI-G cuttings dryer that achieves most liquids/solids separation in large-volume process. Cutting dryer offers operators a important advantage in meeting more and more demanding environmental laws for onshore and offshore cutting disposal in drilling waste management system.

The VERTI-G dryer gives operators a critical advantage in meeting increasingly stringent environmental rules for cuttings disposal. The flow of cuttings into the VERTI-G dryer is PLC-controlled and continuously fed to yield optimum liquid/solid separation. Once cuttings are introduced into the dryer’s charge hopper, widely spaced, independently adjustable flights continuously direct cuttings to the shaker screen surface. Flights are tungsten carbide coated to reduce abrasion and ensure optimum tolerance.

KOSUN 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 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 cuttings dryer has been done with strict balance testing for all major rotary components to minimize vibration & noisy.
