Recently 2 sets of offshore drilling mud cleaner are ready for shipment, the difference of the offshore used mud cleaner with onshore drilling mud cleaner is the lifting point and explosion proof vibration and starter. The lifting pad system conforms to DNV 2.7-1 or CCS lifting certificate to meet for offshore drilling. We can make customized design equipments according to different requirements.


The mud cleaner equipped with 3 ea of 10 inch desander cone and 16 ea of 4 inch desilter cone, all of the hydrocyclones are made of 100% composite material for longer working life, especially when the solids content is very high, we will use metal cover outside the polyurethane material cone in case that the hydrocyclone will be easily deformed and damaged. 2 units of 1.72KW vibration motor from Italy Oli or US Martin brand are used to drive the bottom drying shaker. The lifting frame with offshore approved lifting pad is designed for convenient lifting the equipment from land to offshore rig. We can provide different explosion proof standard motor and starter based on different requirement.


The mud cleaner with a 4 panel screen bottom shale shaker to recovery more useful drilling fluids. All of the screens are composite material frame shaker screen with stainless steel 316 wire mesh, we use 3 layers of wire mesh for all the API mesh over API60, which has been widely used in different countries for oil drilling rig for treatment of different types drilling fluids, the working life is from 300 to 700 hours.
Except for mud cleaner, GN solids control also produce other solids control equipments such as shale shaker (both linear motion shale shaker and dual motion shale shaker), desander, desilter, decanter centrifuge, centrifugal pump, mud gas separator, vacuum degasser, mud agitator, mud gun and drilling waste management equipments.

Recently 2 package of tandem shale shaker are shipped to India client, we have finished the necessary inspection before delivery, water test and mud test under the required API mesh size.


The 2 units of single shale shaker are installed on one oilfield 3 runners skid as tandem shale shaker for convenient shipment and operation. 3 pcs of pre-tensioned durable composite material shaker screens are installed on the shale shaker, the deck bottom are made of stainless steel for better anti corrosion. The shaker deck, vibration beam and all the vibration and non vibration components are all made of stainless steel. The shaker skid are made of structure steel for better strength. The vibration motor and starter including the cables, cable glands are all DGMS approved explosion proof products, which can meet the user’s requirement in explosion proof standard.


The shale shaker is designed to treat both water based drilling fluids and oil based drilling fluids, the operation temperature is -5℃ ~+55℃. We can produce shaker screens comply with API RP13C standard, the API mesh size is from API 20 to API 300 based on client’s requirement. The wire mesh material is made of SS316L for longer working life, and 4 corner pre-tensioned before heating press process will increase the working life of the shaker screens.
The shale shaker is most important solids control equipment and the first phase cleaning equipment for a solids control system, a better performance shale shaker can reduce the drilling waste volume, so that the drilling waste treatment cost will be reduced, and it can recovery more useful drilling fluids for the drilling rig, reduce the burden of next step cleaning equipment like desander, desilter, mud cleaner, degasser and centrifuge.
If you need solids control equipments and drilling waste management system, pls contact with GN solids control.

As one of the most professional shale shaker manufacturer in China, GN solids control can produce not only linear motion shale shaker, but also dual motion shale shaker, recently one batch of dual motion shale shaker are shipped for international drilling company.
The dual motion shale shaker can work under both linear motion and Progressive elliptical motion according to different drilling depth and drilling fluids requirement. The vibration motor can be adjusted on the starter.


The features for linear motion shale shaker:
Higher G force, higher screen conductance, higher treating capacity, direct action on the drilling cuttings, bigger throw vibration angle, the cuttings stay time on the shaker screen is shorter, it is suitable for the drilling fluids with low viscosity, high fluids flow, high solids content, coarse and hard drilling cuttings, especially it is widely used for first spud, second spud of the oil drilling rig.
The features of Progressive elliptical motion shale shaker:


Slow action on drill cuttings, the cuttings stay time on the shaker screen is longer, the screen opening is not easy blocked, the drilling cuttings not easily crushed. It is suitable for the drilling fluids with high viscosity, low flow rate, high solids content, and easily crushed drilling cuttings. Especially it is widely used for third spud, fourth spud of the oil drilling rig.
Whichever the vibration motion is used, the operator can choose it according to different drilling fluids. The shale shaker with 4 panel shaker screen of composite material frame, as one of the most shaker screens manufacturer in China, most of GN produced shaker screen is with composite material frame, we can produce screen mesh size from API 20 to API 300 as per your requirement, and we have stock for the best sold model replacement shaker screens, for urgent requirement, the delivery can be much faster.

Recently one batch of drilling fluids shale shakers are ready for shipment, they are for drilling rig solids control system to separate drilling cuttings from drilling fluids. The waste drilling cuttings will be collected by screw conveyor, and transfer to drilling cuttings treatment system.
The features of GN shale shakers:


1) Shaker deck bottom made of stainless steel 304, which is fluids touch part
2) Patent C tube rubber sealing for better sealing performance and prevent the cuttings from leakage
3) 2 ea of Itavibras / Italy Oil/ US Martin brand vibrator to provide high G force up to 7.5G, whichever is suitable.
4) High grade instructure steel material mounting skid of the shale shaker to provide high strength support
5) When tandem shale shaker and triple shale shaker is required, we will make a complete skid and possum belly for the 2 units and 3 units of shale shakers


6) Our normal shale shaker is linear motion shale shaker, when 2 vibration mode is required, we will make special dual motion shale shaker to meet the client’s requirement
7) Composite material frame shaker screens installed on the shale shaker with longer working life and better separation performance.
8) If required by the client, we can provide ViST unit to increase the separation performance of the drilling fluids, the vacuum hopper is installed under the last piece screen, the vacuum unit provide vacuum so that the drilling fluids can last longer time on the screens, so the discharged cuttings is much drier, and the fluids is much clean.
Except for drilling fluids shale shaker, we also have mud cleaner, vacuum degasser, desander, desilter, decanter centrifuge, mud agitator, centrifugal pump, etc. solids control equiupments and vertical cuttings dryer, high G drying shaker, screw conveyor, vacuum pump, etc. drilling waste management equipments.

Recently GN Solids Control shipped one set of solids control system to Papua New Guinea by air. Because the project is very urgently, the client can not bear the long sea freight time, so they decide to ship it by air by a big cargo airplane. After arrived at Papua New Guinea, the user need to ship the solids control system by Helicopter because of the rough road condition there.
