Drilling cutting dryer designed to process drilling waste with
cuttings. The disposal out of cutting dryer oil content by weight is
about 5%.
In general view, we approach following four R’s
Recycle-recycle the useful material for reuse
Recover-recover the fluid property
Reduce-reduce the cost and waste disposal
Reuse-reuse the valuable products processed by cutting dryer
Aipu cuttings dryer holding high efficiency separation on drilling
fluid and it will minimize drilling cuttings content in drilling fluids.
The cutting dryer decrease disposal percentage benefit much on “0”
disposal application. Separate drilling mud recycled by solids control
system effectively. Recycle the lost mud caused by equipment
failure, etc. The common spare parts are easy to be replaced. The
wolfram carbide alloy knives on cones are changeable also minimize
the whole device failure

3. Aipu Vertical Cuttings Dryer Working Principle
更多选择 · More options
The Vertical Cuttings 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 to pass 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.

5. Drilling Cuttings Treatment Unit and Flow Line
Main Equipment:
1-shale shaker; 2-mud cleaner; 3-auger conveyor;
4-vertical cuttings dryer; 5-waste discharge;
6- recovery of mud; 7- Collection Tank;
8-centrifuge feeding pump or screw pump;
9-centrifuge; 10-solid discharge port;
11- Clean mud recovery mud system.
Flow Line:
Mud from rig enter into shale shaker(1), mud cleaner(2).
After treated by these two steps, the drilling cuttings enter into vertical cuttings dryer
by auger conveyor(3).
Solids enter the Vertical Cuttings Dryer (4) through the top feed inlet and are
separated inside the Dryer.
The clean solids exit the bottom of the Dryer and are discarded overboard (5) or
collected in Cuttings Boxes for offsite transport and disposal. The recovered liquid is
routed to a Liquid Collection Tank (7).
The recovered liquid is conveyed by screw pump (8)
and then processed through a decanting centrifuge (10) for final
clarification, storage, and reuse (11).

6. AIPU Vertical Cuttings Dryer Features
More Applications AIPU Vertical Cuttings Dryer specially designed mainly for oil based mud
High G Force AIPU normal vertical cuttings dryer speed is 900 RPM with G force up to 420 G
Bearing FAG Brand premium bearing.
Rotor Flights
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.
Screen Basket
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. All around flushing
system through specially designed nozzle to avoid the block of the liquid discharge channel.
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
VFD Control Panel
VFD cuttings dryer control panel is pressurized explosion proof. 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.
