One set of dewatering centrifuge package is shipped to Southeast Asia for TBM mud treatment and water recovery project. This is not the first dewatering centrifuge package to be used for TBM mud dewatering project, we ever used it for similar projects several years ago, pls check the working video from our website: https://www.gnsolidscontrol.com/video/gn-solids-control-drilling-mud-dewatering-system-working-video

If you need the customized solution of huge volume mud treatment for TBM, Tunneling, Piling projects or other pipeline laying projects, pls contact with GN solids sales.
The technical specifications are as below:
1) 1 unit of GN dewatering decanter centrifuge laying into the 20ft container, the max speed is up to 3900rpm, the normal operation speed is 3200rpm, with separation cut point by mechanical separation is 2~5 microns. The max G force is up to 3063G, the normal G force is 2062 G, the bowl is made of duplex stainless steel 2205, the screw is made of stainless steel 304. The fluids distribution port and solids discharge port is made of tungsten carbide inserts and it is replaceable. The screw impeller is protected by tungsten carbide tiles for longer operation time.

2) The chemical dosing system installed into a 20ft container, including 3 compartment tank with chemical feeding hopper, agitator, piping system and bracket, PLC control panel and chemical dosing pump. Normally flocculants will be added by the chemical dosing system to the decanter centrifuge feed pipe, so that the ultra fine solids will be accumulated to bigger size solids, the decanter centrifuge can separate them easily, it will increase the separation performance of the high speed decanter centrifuge.

3) The container equipped with doors, windows, air conditioner, lightings, etc. accessories for customer’s requirement. The 2 container design is customized design, usually we will put everything into a 40ft container for convenient transportation or without container as per client’s option.

Recently one batch of drilling fluids shale shakers are ready for shipment, they are for drilling rig solids control system to separate drilling cuttings from drilling fluids. The waste drilling cuttings will be collected by screw conveyor, and transfer to drilling cuttings treatment system.
The features of GN shale shakers:

1) Shaker deck bottom made of stainless steel 304, which is fluids touch part
2) Patent C tube rubber sealing for better sealing performance and prevent the cuttings from leakage
3) 2 ea of Itavibras / Italy Oil/ US Martin brand vibrator to provide high G force up to 7.5G, whichever is suitable.
4) High grade instructure steel material mounting skid of the shale shaker to provide high strength support
5) When tandem shale shaker and triple shale shaker is required, we will make a complete skid and possum belly for the 2 units and 3 units of shale shakers

6) Our normal shale shaker is linear motion shale shaker, when 2 vibration mode is required, we will make special dual motion shale shaker to meet the client’s requirement
7) Composite material frame shaker screens installed on the shale shaker with longer working life and better separation performance.
8) If required by the client, we can provide ViST unit to increase the separation performance of the drilling fluids, the vacuum hopper is installed under the last piece screen, the vacuum unit provide vacuum so that the drilling fluids can last longer time on the screens, so the discharged cuttings is much drier, and the fluids is much clean.
Except for drilling fluids shale shaker, we also have mud cleaner, vacuum degasser, desander, desilter, decanter centrifuge, mud agitator, centrifugal pump, etc. solids control equiupments and vertical cuttings dryer, high G drying shaker, screw conveyor, vacuum pump, etc. drilling waste management equipments.

Recently GN solids control shipped one set of drilling cuttings solidification unit to our client in Africa. The cuttings solidification unit is widely used for water based cutings final disposal. The technical specification of GN drilling cutting solidification unit:

1) GN stand drilling cutting solidification unit is mounted on 2 skid, one is solidification mixing unit, one is cuttings storage hopper skid. During transportation, the solidification unit is loaded into 40ft container, and the 2 separate skid for convenient operation.
2) The cuttings storage hopper skid including waste collection hopper and accessories and screw conveyor , the user can damp the cuttings waste into the collection hopper, the screw conveyor transfer the waste to solidification mixing unit continuously.
3) The solidification unit including lime storage box, absorber storage box, high shear mixer, all of these components are installed on one skid. The screw conveyor dropped the cuttings into the vessel, at the same time, the lime and absorber are transferred by separate augers, all of these materials are mixed into the vessel, and transferred by the inner screw to solids discharged port. If chemical is necessary, it can be add through the liquid inlet .
Before feeding the GN solidification unit, to save the operation and material cost, the drilling cutting should be as dry as possible. The client can use water based drilling waste management system before feeding to cuttings solidification unit.

Normally we use high G drying shaker and high speed decanter centrifuge package. The screw conveyor collect the water based drilling cuttings and transferred to high G drying shaker, the coarse solids are separated out, the fluids dropped into the buffer tank, the screw pump transfer the liquid to VFD decanter centrifuge, then the fine solids are separated out, the fluids are flow to solids control system for reuse, the cuttings are collected by trash box and feed to solidification unit.
