At CIPPE 2014, GN also shown new designed shale shaker with electric deck angle adjustment and vertical cuttings drier.

Lastest designed shale shaker

For the lastest designed shale shaker, it could be both electric and manual adjust the shaker deck angle to control the pool level on the shale shaker screen. By doing so, the operator could control the time of the drilling mud staying on the shale shaker screen, and then adjust the treatment effect. To make the replacement of shale shaker screen easier, the new shale shaker could be fixed with Mongoose shaker screen which greately increases the applicability of GN shaker. While when it comes to cuttings dryer, GN Solids Control is the first one manufacurer with API certificate who could make both the cuttings dryer and big bowl decanter centrifuge.

The Linear Motion Mud Cleaner

GN also showed the linear motion mud cleaner, with underfluids four panel shale shaker screens to give customr drying solids discharge.The composite material shale shaker screen allows drilling contractors to have longer life operation, and saves cost for the drilling.The 1000GPM mud cleaner including two ten inch desander cones, and 12 four inch desilter cones.The shale shaker desander desilter 3 in 1 unit is mostly used for oil drilling rigs either weighted mud or un-weighted drilling mud.

Turkey is in a special position, earthcrust moves very positively, so drilling works, especially the geothermal project around the Eurasia plate boundaries, we got very high tempreture, usually 70~80degree, can achieve 90degree sometimes, as we come in winter this time, it is 65~70. It is high, for water based mud, as we all know water boiled on 100degree, it is for Turkey Cay, and 85 is for coffee. Shaker, screen, cyclones, performamce all are challanged on this situation, after awared of the information from the site, GN Solids Control supplying the different cyclones and updated shaker screens to the geothermal project. And actually we have two options for this kind of geothermal drilling project, one is the updated screen, hook type, or steel frame pretensioned screen; the other is the composite material screens.

We hereby notify that we GN Solids Control are going to update the linear motion shale shaker GNZS853 to GNZS594, after a lot of details improved, and collect the feedback from client.

Remarks	Treating capacity test from mud:1.2g/cm3density & viscosity 45s & API40  screen

The main update this time is the shaker screen, and the screen deck. The shaker screen from metal steel frame type to composite material, more tolerant, and extend nearly 2.5 times of the screen life.

For the user, it is eaisr to install or change the shaker screens, as it is lighter, smaller; while 4pcs did not deduct too much of the screen area.

Update of shale shaker	Description	GNZS853	GNZS594
Shaker Screen	Material	Steel frame	Composite material, steel frame for option
	Diemension, Weight	3panel, 850x1250mm 17.5kg /ea	4panel  585x1165mm     12kg /ea
	Screen life		2.5 times than steel frame
	High drilling mud tempreture		More tolerant
Steel Frame Shaker Screen		Composite Material Screen

For the screen deck, the GNZS594 is stainless steel, and new hollow rubber, sealed in a C type slot.

Shale shaker screens have become complicated in the work of the past 40 to 50 years, Initially, they were simple square openings that were simple to explain. At that time, screens were designated by "mesh" openings. The mesh count is the number of openings per inch in directions perpendicular to each other & parallel to the screen wires, For example, a 40-mesh screen would have 40 openings per inch in direction & 40 openings per inch in a perpendicular direction, In a hard work to eliminate calling the screen a "40 by 40" screen, the common terminology resulted in calling the screen a 40-mesh.
A comprehensive document was approved by API and published in December 2004 and approved by ISO in 2006. Two major changes were incorporated into the Recommended Practice:

* Conductance measurement was made more robust
* A new shaker screen description method was instituted.

Most companies were in accord with the first new procedure. Discord arose, however, with the new description method. This arose because most screen manufacturers and solids control service providers now needed to label their screens as coarser than their original designation. Some screens labeled as "XX175" (implying a 175 mesh) would not capture even 100-mesh particles.
Cut points are not a unique property of shale shaker screens. Other parameters also have an impact including:

* Liquid phase viscosity at the shear rate required to move through the screen
* Screen velocity and acceleration
* Deck angle
* Screen motion
* Solids loading and solid sizes presented to the screen
* The gel structure of the drilling fluid, among others.
All screens have some distribution of openings. The Task Group decided to identify the largest solid that would pass through each screen (or the smallest solid captured by the screen); this is called D100. Solids smaller than D100 will pass through a D100 screen. If a screen is labelled as 200-mesh (74 microns), no 100-mesh (150 micron) particles ought to pass through the screen. Clearly all 80-mesh (180 micron) particles ought to not pass through the screen. If openings are 74 microns by 74 microns, larger particles ought to stay on the screen.
The aim was to describe the size of the screen openings. Most particle sieving and sizing is related to some standard opening sizes. Opening sizes, for example, in a 200x200 mesh screen will depend on wire thickness ASTM Specification E-11 serves as an accepted standard to describe screen openings. The Task Group desired to generate a standard method of describing screen openings that would be reproducible around the globe and would be comparatively simple.
