The vertical centrifuge is also called vertical cutting dryer, it is a very important part for drilling waste management on treating oil-based mud.

Vertical centrifuge could meet environmental objectives by reducing waste volume, maximizing liquid recovery and reducing your project cost. KOSUN can provide all-around drilling waste management as well as solids control equipment.
 

Drilling fluids vertical cutting dryer could be regarded as a vertical centrifuge, the discharged cuttings transferred by the auger get into the screw conveyor. Drilling fluid vertical cutting dryer from the opening on the top, under the function of centrifugal force produced by rotation of the screen module. Liquid flow out from the opening at the flank side while the solids discharged out from the outlet at the bottom of the cutting dryer. The discharged solids water content is around 30%, that means there is no flowing water, so it could be transported easily.

Vertical cutting 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 to 900RPM with G force up to 420. 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 vertical cutting dryer proper operation. KOSUN Vertical Cutting Dryer has been done strict balance testing for all major rotary components to minimize vibration and noise. The cutting dryer is the ideal products for oil-based drilling waste management.
