Extractor,  most commonly called vertical cutting dryer,it is the main equipment for drilling waste management. GN Extractor utilizes centrifugal force to dry drilled solids in oil or synthetic based fluids.

In extractor (cutting dryer), a stainless steel screen bowl traps “wet” solids and accelerates them up 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 proper operation.

GN extractor (cutting dryer) has been done strict balance testing for all major rotary components to minimize vibration & noisy.It is the ideal products for oil based drilling waste management.

How waste management system processing (oil based mud):

1) cuttings from shale shaker, desander,desilter comes into verticalcutting dryer through screw conveyor (auger)

2) After treatment of extractor:

a. useful mud back to recycling system for dilling.

b. waste solids discharged

c. recycled drilling fluids comes into GN Decanter Centrifuge for recovering.
