The Drilling Cuttings EXTRACTOR Dryer receives drill cuttings from the Solids Control equipment via screw conveyor, vacuum system, and/or solids pump.Drill cuttings are fed into the centre of the feed cone and distributed evenly through feed holes by centrifugal action into the fl ighting channels between the scroll and the screen. As the drill cuttings pass through the conical screen, the solids layer becomes thinner and exposed to progressively more G-force.
Features of GN Drilling Cutting Extractor Dryer
The GN Vertical Cutting Extractor 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 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 cutting dryer has been done strict balance testing for all major rotary components to minimize vibration & noisy.
Summary of the Drilling Cutting Extractor Dryer
EXTRACTOR Dryer is designed to remove NADF from drill cuttings exiting the shale shaker. The dryer is capable or reducing the oil on
cuttings to < 5% and to an overall total of < 6.9% when the centrifuge waste is taken into account. Excess fl uid is recovered after centrifugation
and returned to the active system for reuse. The system is not suitable for the treatment of water based mud cuttings.
