Vertical Cuttings Dryer

Categories:

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 with G force to 420G. 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 Vertical Cuttings Dryer Features and Benefits

Flights on the Rotor

The Flights on the rotor is hard facing to HRC 65, longer life than our competitors

The flights and the rotor assembly is individually balanced for future replacement

Stainless Steel Screen

Specially designed highly precise stainless steel screen to ensure your better separation, longer life and easy replacement.

The screen itself is individually balanced for future replacement. And the screen is separated from the frame which allows you to change the screen only, not need to change the frame inside.

Air Knife

Special high pressure air knife design to clean the basket screen automatically to avoid the screen blinding especially for high viscosity mud and water based mud

Oil Lubrication System

Individual oil lubrication system with automatic alarm for pressure limit. The main motor and oil pump motor is interlocked with each other for avoiding the start of the main motor prior to the start of the oil pump motor.

Flushing System

All around flushing system through specially designed nozzle to avoid the block of the liquid discharge channel.
