GN solids control shipped several units of vertical cuttings dryer and decanter centrifuge to Russia with customized painting color. As the expert of solids control & drilling waste management in China, we have exported a lot of vertical cuttings dryer and decanter centrifuges to Russia area.

The vertical cuttings dryer and decanter centrifuge is the major equipment of zero discharge system for oil based drilling cuttings treatment. The working process is as below:
The screw conveyor collect the oil based drilling cuttings from the shale shaker of solids control system and discharged to 2# screw conveyor, the 2# screw conveyor is installed slantly and transfer to vertical cuttings dryer top open feeding port. The vertical cuttings dryer dry the drilled solids from oil based cuttings by centrifugal force. The screen basket traps the fluids and accelebrates them up 900rpm and G force is up to 420G. The fluids is discharged from the liquid discharged port and flow to intermediate tank, the feed pump transfer the liquids to decanter centrifuge to separate fine solids, the cut point is 2~5 microns. The clean fluids is recovered by the catch tank or connect the pipeline back to solids control system for reuse.

VFD decanter centrifuge should be applied for drilling waste management system, which with 3 motor frequency VFD, main motor, back drive motor, pump motor. We use ABB brand inverter for easy outsourcing when need to be replaced, all the other electrical components are also with ABB, Siemens, Schneider with good quality. Our VFD control panel is positive pressurized VFD control panel with PLC smart control and HMI interface. The screw pump as centrifuge feeding pump flow rate can be adjusted by changing the motor speed.
We also produce complete drilling waste management system with our standard compact design, for cold area, we can install the system inside the container.
