Solids control system will meet different cutting point when running
Shale shaker use for size>70 micron solid particle as the important part of total system
As the first step,GN shale shaker use linear motion,can remove the big size cuttings,and keep high effectiveness,work for second step of whole system,solid&liquid separate result will effect rest solids control step
The applicable range of drilling fluid vibrating screen:
Ground / offshore oil / gas drilling / CBM excavation / Trenchless Directional Crossing / piling / waste water / mud treatment etc., primary and two or three stage solids handling of mud and liquid to be treated. mostly, it is the primary treatment of mud and solid liquid mixtures applicable to various environments.
The performance can be expected and operation direct to watch . Shale shakers provide the advantage of not,easy manage and maintain,shale shakers can produce a sure dry cuttings discharge.equipment’s main job is remove as much solids as possible and reduce the solids loading to the next level, the shale shaker is the primary solids removal device. It is usually relied upon to remove all drilled cuttings coarser than the weighting material. Downstream equipment will often remove too much valuable weighting
Numbers shaker should be installed to process the whole circulating with the target of removing as much drilled cuttings as economically feasible. because as the important part of the system, need arrange enough quantity shale shaker and put at suitable place to achieve optimum economic performance of the solids control system.
The working principle
mainly by the screen frame, screen exciter, damping element composed of drilling fluid shaker, by the mechanical vibration is bigger than the mesh of solid and solid adsorption by mesh sieve out some less than. The drilling fluid returned from the well head flows from the feed tank to the surface of the vibrating screen. The solid phase is discharged from the tail of the screen and contains a liquid phase smaller than the solid phase of the mesh. The sieve flows into the drilling fluid system to complete the separation.
Safety operation of shale shaker for drilling fluid:
It must be determined that the transport locking device is removed prior to use. The equipment can not be repaired, moved or even removed by the use of the vibrating screen. The equipment shall be operated and maintained according to the safety instructions and warning signs given on the equipment.
Maintenance of mud drilling fluid vibrating screen:
According to the vibration motor safety warning, the motor rules, reasonable maintenance, such as filling lubricating oil, etc.;
In the process of use, the screen should be carefully observed, inspection and so on. The damaged screen mesh and the completely damaged screen shall be repaired or replaced in time;
Make necessary cleaning of vibrating screen and screen so that the screen can have a longer life, after each end.
In order to make the use of vibration screen to achieve the best, regularly and systematically monitor the overall situation of the vibration sieve and maintenance.

Submersible slurry pump also called pit pump, usually installed in pit or mud tank vertically to transfer the mud from the pit/mud tank to shale shaker or other solids control equipment. Compared with centrifugal pump, the pit pump impeller is more anti-wearable. Even when there are some big particles in the mud, the pit pump can still work well with longer lifetime.
Recently, we got big order from overseas client requiring 10sets submersible slurry pumps. The client had good experience with GN slurry pump about two years before, and he trust GN slurry pump working performance. After the client get the contract, he came to GN Solids factory to check our new factory, new production facilities, new office building and new warehouse. The client was amazing with the fast development of GN Solids in past two years. Orderly management, hard work and good product bring GN the prosperity. The client signed purchase order with GN Solids before he went back to his country. Except for the slurry pump, the client also bought some sets of centrifugal pumps, shear pump and screw pump etc.
About 5 years ago, one old client from India bought 2sets complete mud tank system for their oil drilling rigs.

Mud treatment is required in many different industries. For GN Solids, the most popular mud treatment is oil drilling mud treatment, or HDD mud treatment. In recent years, we have more and more project from other industry mud treatment, like piling mud, TBM mud treatment, or construction mud treatment. One batch of mud separation equipment for US client, ready for delivery. The client will use the equipment to treat the construction mud.
The mud will be collected by one big hopper with wide opening, and then transfer to high G drying shaker, to separate the big solids particles.
GN high G drying shaker is equipped with 4 panel composite material shaker screen or coarse steel screen per client’s request. The longer shaker deck can give better separation, and make the solids discharge as dry as possible. The super G force also very important to the dryness of discharge solids.
The high G drying shaker is seated on the catch tank with submersible slurry pump. The slurry pump can suck the mud and feeding to next unit for further treatment.
We just finish the tourist trip to Thailand and back to China yesterday. As the leader manufacturer for solids control equipment & mud system, we are always available even when we were for Tourist in Thailand.

High speed gravity separation technology help GN Solids to produce high quality decanter centrifuge, to serve domestic and overseas clients, by offering solids control and drilling waste management solutions, to develop GN into China high end technology company.
GN has various model centrifuges for option with different bowl size and different capacity, with different speed to separate different size particles.
1) GN 9inch baby centrifuge with only 9inch bowl size, and treating capacity will be 3-5m3/h. Normally, mining project / diamond drilling will require the small centrifuge to give better performance of mud treatment. What’s more, the cost of small centrifuge is very cheap.
2) GN 14inch bowl centrifuge with 14inch bowl size, and ration of length to diameter is over 3, to guarantee on the separation performance. The treating capacity for drilling mud can reach to 15m3/h to 25m3/h per the mud weight, viscosity etc. This model decanter centrifuge is equivalent to Swaco 518 centrifuge, Swaco 414 centrifuge, Derrick DE1000 centrifuge etc.
Many drilling contractor stop centrifuge renting service of Swaco branch or centrifuge renting service of Derrick company, they come to GN to buy their own centrifuges, and GN can offer training on centrifuge operation and maintenance. In long term, the drilling contractor can save lots of cost on mud treatment.
3) GN 18inch bowl centrifuge with 18inch bowl size and there are two options:
GNLW452 with 1800RPM bowl speed, which is specialized for barite recovery; the price is much better.
GNLW453-VFD with 0-2500RPM bowl speed, which is specialized for fast mud weight cutting, the centrifuge is controlled by VFD control panel & AC for cooling. The price is relatively higher.
4) GN 22inch bowl centrifuge and GN 30inch bowl centrifuge.
The big bowl big volume centrifuge is generally used for construction, TBM machine, Subway construction etc. In the mentioned project, large volume of mud will be engaged, and big capacity centrifuge is necessary to guarantee on the project period.

About solids control equipment tender
When there is a tender, at least three solids control brand will compete to win the tender. What is the GN advantages when competing with US brand or other China brand ?
1) The first advantage of GN is on solids control equipment tender. Our sales people have strong reading ability to thick documents with quite a few pages, picking out the important parts, discuss about it and offer correspondence.
But GN generally doesn’t bid for overseas tender directly. We can support local company and the client can bid for tender in name of local company, but with technical support / commercial support from GN Solids Control.
2) GN can offer the most higher cost-effective solids control equipment from China. GN marketing position is only focus on high end client, with international standard products. Compared with US brand, GN can offer similar performance equipment with much better price. Compared with other China supplier, GN solids control product surely can work much better, no compares.
About registration to big companies
In the past years, GN Solids already successfully registered to many big drilling companies/ oil service companies. GN is registration supplier for CNOOC, PDVSA, NIDC, PDO, EDC, BAKER HUGHES, BAROID, etc.
In the New Year, we will be ready to register into supplier for more companies.
Shaker and mud cleaner is the most common item in solids control system. With high reliable shaker and mud cleaner, the mud system can work in higher efficiency, less maintenance, longer lifetime. GN shale shaker and mud cleaner, have been working for oil and gas drilling almost 10 years. With rich production experience combining with jobsite commissioning experience, GN have optimize the shaker and mud cleaner, make them much user friendly and high efficiency.
GN Solids Shale Shaker
GN Solids shaker have different models for option, including
2 panel shale shaker for mining/diamond drilling/ other small well drilling
3 panel shale shaker for CBM drilling/HDD drilling/Workover rig / Oil drilling etc.
4 panel shale shaker for oil and gas drilling, usually for deep well drilling rigs. This model GNZS594E-HB screen size is same as Swaco Mongoose screen. We can offer both composite material shaker screen and carbon steel frame shaker screen. After some years jobsite experience, composite material shaker screen can work better performance, and longer lifetime. Price of composite material screen is little higher than steel frame screen, but more cost-effective.
GN Solids Mud Cleaner
Mud cleaner is assembly of shakers, frameworks with desander cones and desilter cones, smaller footprint, and same function. Some client may not need the deck shaker, and we can offer the frameworks with desander cones and desilter cones. This is totally can be customized according to client’s need.
GN Solids mud cleaner model is decided by the model of shale shakers. We also have three models:
- Option 1: no shaker mud cleaner. Desander, desilter or assembly of desander and desilter
- Option 2: Mud cleaner with 3 panel shaker
- Option 3: Mud cleaner with 4 panel shaker
Sometimes, the selection of shaker is depending on the tender requirements. If the client buy and use it for themselves, they can choose better and lower cost models.
