GN Vertical Cutting Dryer
The GN Vertical Cutting Dryer uses centrifugal force to dry drilled solids in oil or synthetic base fluids. Astainless steel screenbowl traps ¡°wet¡± solids and accelerates them up to 890RPM 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. GN Vertical cutting dryer has been done strict balance testing for all major rotary components to minimize vibration & noisy.The Cutting Dryer is the ideal products for oil based drilling waste management.

GN Vertical Cuttings Dryer Features and Benefits
The GN 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 900RPM. 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.
- The flights are made from hard high chrome alloy material to be anti-abrasive from solids and?ensure long operational life vertical cuttings dryer.
- Air Knife is Provided for cleaning the screen to avoid screen blinding.
- Balance testing for all major rotary components to minimize vibration & noisy
- Individual oil lubrication system with automatic alarm for pressure limit.
- Screw conveyor installed under the dryer to pick up the dry solids for continues operation.
- Cleaning pump provided for avoiding solids accumulation in the cuttings dryer
