KOSUN Vertical Centrifuge Uses Centrifugal force to Dry Drilled Solids

Vertical centrifuge 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 screw conveyor ( auger ) and transfered to feeder of the vertical cutting dryer.

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.

The 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.

KOSUN is the leader in domestic solids control industry and expert in waste treatment. We are capable of providing customers with such three series as oil & gas drilling solids control equipment, centrifuges and drilling waste treatment equipment.Since its establishment in 1992, it has been working on continuous development of solids control and drilling waste treatment technologies.
