GN High G Drying shaker and mud agitator for Middle East Customer

One batch of GN High G drying shaker and mud agitator are shipped to Middle East customer.

The high G drying shaker is mainly used for water based drilling cuttings treatment, it can be also used for oil based drilling cuttings before or after vertical cuttings dryer, to reduce the solids content of the drilling cuttings and improve the separation efficiency of the vertical cuttings dryer and decanter centrifuge. The client can use different mesh size shaker screens for the drying requirement of the drilling cuttings.
GNZS594K-GZ high G drying shaker is the most popular model high G drying shaker, which is drived by 2ea 2.3HP vibration motor, the max G vibration G force is up to 8.0G and it is adjustable. 4pcs of composite material frame shaker screens are installed on the high G shaker, the screen area is 2.73m2, the deck angle is adjustable from -1°to +5°, the feeding method is hopper feeder. We can provide CNEX, ATEX and IEC EX for different requirement.


The mud agitator is used for drilling mud tank system, it is used for stirring and mixing of the drilling fluids to prevent the solids particles of drilling fluids from depositing in the mud tank system. Features of the GN G series mud agitator:
1. Helical bevel type gearbox is adopted, with compact structure, good agitating performance, reliable operation and less maintenance parts
2. The explosion proof motor is directly connected to the input shaft of the gearbox, compared with the E series mud agitator which with connection coupler, the structure is more compact, less wear parts, easier maintenance.
3. The combination of helical bevel type gearbox and explosion proof motor is good for working under harsh conditions

GN Drilling Cuttings Treatment Equipment for Middle East Customer

One batch of GN drilling cuttings treatment equipments are ready for delivery to Middle East customer, including 3 sets of high G drying shaker GNZS594K and 2 sets of vertical cuttings dryer GNCD930G.
What is the difference of high G drying shaker with vertical cuttings dryer?
1. Application difference: The high G drying shaker is normally used to treat water based drilling cuttings, the vertical cuttings dryer is normally used to treat oil based mud/ drilling cuttings.


2. Working principal difference: High G drying shaker ( also called as high G dryer) is high vibration G force shale shaker with fine mesh shaker screens. It is drived by 2ea vibration motors, the shaker screen is 4 pcs of 585x1165mm composite material frame shaker screens. When the water based drilling cuttings are feed to high G dryer buffer tank, the massive G force immediately pins solids against the fine screen mesh ( as fine as 200 mesh/74 microns).Liquid passes through the screen and is recovered, while dry solids are conveyed and out by augers.


Vertical cuttings dryer ( also called as verti-G dryer), when the OBM or SOBM wet cuttings are feed to verti G dryer feeding port by screw conveyor, A stainless steel screen basket traps wet solids and accelerates it up to 900rpm with up to 420G, the liquid is forced through screen openings, the dry solids are extracted by the angled flights attached to the rotor, which rotate slightly slower than the screen. The tungsten carbide protect the flights from abrasive solids and ensures longer operation life.
3. Treatment result is different.
The high G drying shaker can dry the WBM drilling cuttings with moisture less than 30% ~ 40%, the vertical cuttiings dryer can dry the SOBM drilling cuttings with OOC <5%, which can be sent to Thermal Desorption Unit for further treatment.

High G Drying Shaker and Decanter Centrifuge for Oman Project

Recently one batch of high G drying shaker and decanter centrifuge are ready for shipment to Oman, including screw conveyor transfer hopper, high G drying shaker module, decanter centrifuge module. The technical configuration is as below:


1. High G drying shaker module, GNZS594J high G drying shaker installed on the mud tank, with screw conveyor transfer system to transfer the drilling cuttings automatically. Four panel composite material frame shaker screens with 2 or 3 layers of stainless steel wire mesh are installed on the shale shaker, the shaker screen is produced comply with API RP13C standard.


2. Decanter centrifuge module, GNLW363D decanter centrifuge installed on the mud tank, with screw conveyor transfer system to transfer the discharged solids to cuttings collection box automatically. Also we can provide variable frequency drive decanter centrifuge with better treatment performance.
Firstly the drilling cuttings are feeding to high G drying shaker to separate coarse solids and reduce the solids content, the fluids will drop into the mud tank under the high G drying shaker, the screw pump will feed the fluids to high speed decanter centrifuge to separate fine solids from the drilling fluids, the clean fluids will be recycled and back to solids control system to prepare for new drilling fluids, the drilling cuttings are transferred by the screw conveyor.
This system is customized designed for water based mud drilling cuttings treatment project in Oman, with electric control system and electric motor compliant with ATEX standard. For OBM and SOBM drilling cuttings treatment project, GN standard GNCM-40A drilling waste management system will be recommend, which consists of GNCD930G vertical cuttings dryer, GNLW363D decanter centrifuge with feeding pump, screw conveyor, mud tank skid and accessories.
