shaker screen

A lot of clients are asking for ViST Vacuum Shale Shaker Screen Technology to GN solids control, now the technology is already available to sell, pls contact with GN sales engineer to get more information, and understand more from the video : http://www.gnsolidscontrol.com/vist-vacuum-screen

Based on different site schedule, the installation of Vist vacuum shaker screen unit have 2 ways: 1) it is installed externally of the shale shaker, there is one pipe to connect to the last shaker screen of the shale shaker; 2) it is installed under the last shaker screen of the shale shaker when there is enough room.

The purpose to install the vacuum is to reduce drilling waste:
1) Reduce the volume of drilling waste, the drilling cuttings will be much drier, the fluids on the cuttings is reduced 30% to 50%, so the further drilling waste treatment cost is much cheaper, or the transportation cost of drilling cuttings is cheaper
2) Increase the drilling fluids recovery efficiency, save the cost to prepare new drilling fluids
3) Save the cost of the client to buy more equipments, such as drying shaker, shaker screens, vertical cuttings dryer, etc, also save the space to install these equipments

Hebei GN Solids Control
Co., Ltd is a top manufacturer of solids control
system and equipment
in China with a 65000m2 facility in an industrial
area near the Capital City Beijing. With around a decade’s development, Hebei
GN Solids Control Co., Ltd has established a medium-high end customer target
brand- GN Solids Control.  During these
years, GN Solids Control has designed and manufactured many sets of solids
control systems for oil and gas drilling operating now in Europe, Asia,
America, Africa. And about 250 shale shakers are sold a year. Besides a
facility for solids control equipment and systems, GN Solids Control also owns
a specialized facility to manufacture shale shaker screens
in Asia largest mesh and weir centre city, not only supplying shaker screens
for GN shale shaker,
but also replaceable shaker screens for world-wide famous brand shale shakers
such as MI-Swaco; Nov Brandt, Derrick and so on.

Shake screens plays a
very important part in the solids control system for it will decides the
performance of first stage treatment equipment shale shaker which lays the
fundation for the next stages treatment. Also shaker screens are consumable, so
it will cost a lot it change frequently for a bad quality. Supported by a frame
or hookstrip,  shale shaker screen always
use stainless steel as raw material for a good quality.

Another important
criterion is screen mesh. Thread is woven into cloth, similarly, metal wire can
also be woven to create a metal cloth. Mesh means the number of holes in one
inch’s length. And, the larger the number is, the smaller solids can be removed
out. For many years, screen mesh has evolve in competitive screen
manufacturing, contributing to the usage of thin but strong cloth to improve
screen’s service life and conductance.
