The persons who know solids control equipment may know well on the shale shaker and mud cleaner unit. These 2 machines are very common in solids control system that do solids separation job from the first to forth stage. The shale shaker is located at the very beginning of the mud recycling system for primary solids control; the coarse cuttings could be removed by the shale shaker. While after treated by the shale shaker, the drilling fluids would be transferred to the mud cleaner for further treatment.
For the purpose of easy maintenance, in the same solids control system, the mud cleaner is equipped with under drying shaker that is same model as the primary shale shaker. Mud cleaner is just a machine on which the cyclone frame was fixed above. The mud cleaner unit is only able to be used to separate the solids via the hydrocyclone units. Why the mud cleaner unit cannot be used as a shale shaker even if it has the under drying shaker? This is really a good question. GN’s engineer equipped a logging tank to the mud cleaner unit and the mud cleaner unit becomes a shale and mud cleaner composition unit.

GN Shaker & Mud Cleaner Composition Unit

Normally, GN’s shaker unit has back type logging tank that is used to collect the drilling fluids coming out from the drilling hole. The drilling fluids accumulated in the logging box firstly and then overflow into the shaker deck, thus the shaker screen will not be damaged by the high pressure drilling fluids. This unit could be used as a shale shaker unit.
De-sanding and de-silting cyclone are installed on the mud cleaner for finer solids separation. The solid discharged out from the bottom nozzle of the cyclone also has high pressure that will shorten the screen life if directly dropped onto the screen surface. To avoid this situation, there is a hopper collection box that is used as buffer between the cyclone and screen. To make this machine compact, GN’s engineer designed to insert the buffer box into the logging box, which means the logging box is also used as second buffer box for the cyclone unit. This is the function of mud cleaner.
One thing need to be noted is this shaker and cleaner machine can only be used for one function one time: either shaker or mud cleaner. This is a cost saving unit with small footprint, for some project not very urgent, this unit could be a very ideal choice. GN ever showed this unit at Beijing CIPPE, much attention was attracted there.

Shaker screen users may know that there are flat type screen and pyramid type screen used very often on the shale shakers to separate the cuttings from the used drilling fluids.
The flat type shaker screen are very common in screen application, with 3 layers wire mesh stacked and closely connected with the steel back frame. Always there are hook strip type and steel tube frame type screen. Different from the flat type screen with a flat shape screen panel, the pyramid type screen is designed three dimensions screen panel like a wave. This pyramid screen design firstly issued by the world No. 1 solids control equipment manufacturer of Derrick Equipment. And they do have patent for this design.

Comparing with flat type screen, the pyramid type screen has below several advantages.
1. Make a larger effective screen area. Due to the wave type with top and troughs, in fact, the screen panel has a larger screen area than the flat type if the screen panels have same width and length. The pyramid screen let more drilling fluids distribute on the screen and more fluids will with solids less than the mesh will go through the screen.
2. Under the G force and gravity, the solids will accumulate at the troughs of the screen. Comparing with the flat type screen with solids distribute uniformly on the whole screen panel which will impede the go though the screen, the pyramid screen has the wave top and slopes at both sides will let drilling fluids come through.
3. The pyramid screen will make the fluids distribute as a much thinner layers which also helps to increase the flow rate and make the solids much dryer. And it can also separate solids around 3 meshes finer than the flat type screens.
These advantages pyramid screen will especially appear more clear when fed with larger volume drilling fluids that can submerge the screen panel. Thus the full screen effective area will be fully used.

Shaker Screen is one of the very often uses wear parts for drilling process. When starting the drilling process, the shaker screen is installed on the shale shaker unit to separate the solid particles in drilling fluids. The fine holes on screen panel could block the solids larger than the hole size, while the liquid could go through easily. On oil field, most of the shale shaker unit is using 3 or 4 panel screens. According to different condition of the drilling fluids and usage, the driller need make some inventory of the spare shaker screen.

Shale shaker is a most popular equipment uses in drilling mud primary solids control system. According to different processing result and mud condition, the operator may choose the shale shakers with different vibration motions. Nowadays, the most often heard of the shale shaker vibration motion are the linear motion and elliptical motion. GN now has a new development shaker could realize the vibration motion changing during running between linear motion and progressive elliptical motion.

Below the Dual Vibration Motion Shale Shaker Parameters:
