How is the vertical cutting dryer dry-off the drilling fluid?

Drilling waste management is to treat and recover the solids generated during drilling and finally meet environment protection and discharge standards in countries and regions locally. It can meet the requirement of unlanding treatment of drilling mud, effectively prevent environmental pollution, save drilling mud and reduce drilling cost. At present, there are many drilling waste management methods and devices with different treatment effects. Based on the conditions of various drilling sites at home and abroad, the primary and prevailing drilling waste management method is dry-off.

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

1. Reduce Environmental Impact and Meet Compliance Regulations
As regulations on drilling waste become more stringent, operators are in need of a reliable waste disposal solution that ensures the waste and the liability of its impact are gone for good. KOSUN Vertical Cuttings Dryer can offer a reliable solution by reducing the oil on cuttings ratio of oil-based fluids to an acceptable limit for waste disposal.

2. Maximize Separation to Maximize Savings
KOSUN Vertical Cutting Dryer was designed to provide efficient throughput for high rop operations. Its high capacity processing provides substantial reduction to the oil-on-cuttings ratio to help meet compliance regulations for waste disposal. Maximum separation of solids and liquids can be achieved. Increased separation means increased fluid recovery, lower cost of replacement fluid and minimal waste to be transported and disposed of, going straight to your bottom line.

3. Integrated and Customized Packages to Meet Your Needs
Low gravity solids and other waste can ruin the integrity of the circulating system. KOSUN Cutting Dryer is one piece of the solids control system designed to remove solids and keep your operation running smoothly. KOSUN adheres to our rigorous mainstay process to design, test and implement the right solids control system for your rig.

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.
