Drilling waste management system is geting more and more popular while environment issues. It’s not allowed to delivery fluid in some countries. Normally it will including vertical cutting dryer/ high G shaker and decanter centrifuge.

Vertical Cutting Dryer

The GN vertical cutting dryer uses centrifugal force to dry drilled solids in oil or synthetic base fluids. A stainless steel screen bowl straps “wet” solids and accelerates them up 600RPM. 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 then the bowl. Tungsten carbide protectds the fliglhts from arasive 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.

High speed decanter centrifuge working principle

Separation of solids and fluids is done in the drum. It’s principles is : high speed rotating drum drive inner mud rotate speedily and then the ud is thrown on drum’s surface to form a fluids circle. Under the centrifugal force, solids sedimentary force in the separated liquid will be several hundred even thousands of times heavier than it’s own  gravity so as to separate the soldis from the suspension quickly. The ratio of centrifugal force which the solids have gained and the solids’s gravity is called as separating factor. The larger the centrifugal force, the finer the separated solids, so thress types of centrifuge can get according to separating factor
