Vertical Cuttings Dryer

Vertical Cuttings Dryer

Waste Management.


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 or super high speed 1200RPM with G force to 750G. 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

GN Vertical Cuttings Dryer Features

More Applications GN Vertical Cuttings Dryer specially designed not only for oil based mud, SBM but also can be used for water based drilling waste.
High G Force
  • GN normal vertical cuttings dryer speed is 900 RPM with G force up to 420 G, and the Super high speed is available at 1200RPM with G force up to 750G for better separation ability.
  • FAG Brand premium bearing.
  • 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.
  • 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.
Vertical Dryer
  • 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.
  • All around flushing system through specially designed nozzle to avoid the block of the liquid discharge channel.
  • 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
  • GN VFD cuttings dryer control panel is made by stainless steel with Pressurized explosion proof. The PLC smart control allows you to adjust the speed and protect the machine more friendly.
  • The air circulation through the cooling tubes allow you to use the VFD cuttings dryer in high temperature environment.
  • The VFD is ABB or SIEMENS Brand, other main electric components are Schneider or SIENMENS Brand.
