As the name implies, the Shale Shaker basket moves in a uniform circular  motion when viewed from the side. This is a “balanced” vibration  pattern because all regions of the shaker basket move in phase with the identical pattern. In order to achieve “balanced” circular motion,a vibrator must be located on each side of the shaker basket at its centre of gravity (CG) with the axis of rotation perpendicular to the side of the basket. The Brandt Tandem is a common example of a circular motion shaker.

Linear Motion

Linear motion is achieved by using two counter rotating vibrators which,because of their positioning and vibration dynamics, will naturally operatedin phase. They are located so that a line drawn from the shaker’s centre ofgravity bisects at 90˚ a line drawn between the two axis of rotation.

Because the counterweights rotate in opposite directions, the net force on the shaker basket is zero except along a line passing through theshaker’s centre of gravity. The resultant shaker motion is therefore “linear”.The angle of this line of motion is usually at 45-50˚ relative to the shakerdeck to achieve maximum solids conveyance. Because acceleration isapplied through the shaker CG, the basket is dynamically balanced; thesame pattern of motion will exist at all points along the shaker.

Linear motion shakers have become the shaker of choice for mostapplications because of their superior solids conveyance and fluid handling capacity. Solids can be strongly conveyed uphill by linear motion. The uphill deck configuration allows a pool of liquid to form at the shaker’s feed end to provide additional head and high fluid throughput capability. This allows the use of fine screens to improveeparation performance. The Derrick Flo-Line Cleaner is one example of a linear motion shale shaker.

What is dewatering unit
Dewatering unit is a mixing system to mixing chemicals and drilling mud for floculation. After floculation, the very find solids will be formed into bigger size, and suitable for decanter centrifuge treatment.
For easy understanding, we can see that, it is similar like put orange juice into a cup of milk.  It is milk whilte originally, after mixed with juice, immediately, the milk is separated into floccus and pure-like water.

Sizes of dewatering unit
Dewatering unit is noramally put into container, there are 20ft containerized and 40ft containerized. Per different customers request, there are different design for the dewatering unit itself. There are 2-chamber dewatering unit and 3-chamberdewatering unit. And per defferent request, it can mixing chemicals from 1 ~ 3 kinds.

Dewatering cantrifuge for dewatering unit
Decanter centrifuge is normally used in dewatering unit. Per the jobsite footprint, the decanter centrifuge have 3 kinds of connections with dewatering unit:
1) The decantering centrifuge can put into container, connected with dewatering unit
2) The decantering centrifuge can put on the top of container, connected to dewatering unit
3) The decantering centrifuge can put outside container, connected with dewatering unit

How to order a suitable side dewatering unit?

If you want customized dewatering unit, you’d better try to answer below questions:
1) 2 chambers or 3 chambers request: 3 chamber is more widely used. 2 Chamber cannot continue mixing.
2) The chemical preparing speed (Liters/Hr): 1500liters/hr is a normal speed, customer can request customized mixing speed
3) Density of chemicals, in order to make sure the hopper size
4) Chamber capacity (if there is)
5) Other special request (if there is)

Naturally, drilling conditions and cuttings volumes modify constantly through the course of constructing a wellbore. Dual-function and small space is recognized by essentially the most project contractor. GN 705E Double deck dynamically manages fluid excellent all through the drilling procedure. The double deck shaker with de sander or de silter is widely applied for the HDD and nicely drilling field

1. Double deck shaker with 1 de sander hydrocyclone cone

Fluids will firstly be pumped onto the bottom shaker, the shaker screen is tiny API quantity to separate the huge particle from the fluid. Secondly, GN high productive centrifuge pump will transfer the fluid to de sander cone for second step process. The leading deck will manage the fluids from apex of de sander cone.

2 Double deck shaker screen with 4,6 or 8 sets of de silter cone
The working principle is definitely the similar as the de sander. But the feeding sort is quite uncomplicated pipe which can save the operating space. Higher mesh shaker screen is applied on the shaker than desander shaker.

GN double deck shaker delivers the flexibility necessary to optimize fluids capacity and fluids recovery. Also, it fits nicely within tightly constrained workspaces. For the jot website, GN double deck shaker is very sensible program.

CBM drilling is the short name of Coal Bed methane. 95% of CBM drilling is getting nature gas. It is very different with oil and gas drilling. Oil and gas drilling rig normally need to drill very deep well to get crude oil, while CBM drilling is normally in small depth.  

As the special features of CBM drilling, it has higher standard for drilling fluids. High quality bentonite is widely be used for CBM drilling mud systems.

As the high request on environmental protection, zero discharge mud system for Coal Bed Methane drilling necessarily should be equipped.

GN international high standard Zero discharge mud system for CBM drilling

1) GN double deck shale shaker with 4×4 inch desilter cone.

It is the first stage and the third stage solids control process. The double deck shale shake combine the function of shale shaker and desilter.

2) Baby centrifuge GNLW223VFD with small PLC control for VFD. It is used as forth stage solids control.

3) Mixing hopper and mixing pump for mud mixing

The mud tank can be skid mounted, mobile mounted, or equipped with hydraulic jack up legs for self-lifting.  

Characteristics of GNZS594 4-panel high G force shale shaker
GNZS594 is often a high quality 4 panel higher G force drying shale shaker for drilling waste management system. The drying shale shaker with adjustable higher G force as much as 8.0G. It can be suitable for distinction job web-site application, from mud solids manage to drilling waste management.
Moreover, shaker screen of GNZS594 higher G force drying shale shaker is interchangeable with Swaco Mongoose shaker. It might reduce customer?ˉs storage price. The buyer is easy to supply replacement shaker screen locally. They could storage for screen for their very own use as well as distribute to other consumers.

In which program GNZS594 ¨Cpanel drying shale shaker might be utilized
1) Water primarily based mud drilling cuttings remedy. It is made use of as a dryer to drying the OBM cuttings. The fluids phase is going to be additional treated by decanter centrifuge with high speed.
2) In some situations, GNZS594 ¨Cpanel drying shale shaker can also be employed to treat oil based drilling cuttings, as an option of vertical cuttings dryer. However it cannot separate as dryer as vertical cuttings dryer.
3) When lower the G force (normally about 6.0 G ~ 7.0 G )and modify the feeding form, it may be utilised as a standard mud solids control shale shaker at mud cleaning technique.
