Recently one unit of triple shale shaker is ready for shipment to a drilling company in China. The 3 units of shale shakers are installed on one skid for convenient installation and transportation. Each shaker with its buffer box, and the triple shale shaker with a possum belly for mud pipeline connection.

GN conventional triple shale shaker can be updated to vacuum screen technology for option if the client need to improve the separation efficiency, recover more drilling fluids and get drier drilling cuttings. The ViST pan is installed under the last screen ( at cuttings discharge end) of the shale shaker, a suction hose is connected to ViST vacuum unit, the compressed air creates suction on the last screen surface, pulling additional fluids off the cuttings, the liquid on the cuttings can be reduced 30%~ 50%. The vacuum screen technology increase the volume of recovered and reused fluids and produce drier cuttings. Once the drilling waste volume is reduced, more drilling fluids will be recovered, it will reduce the drilling cost for drilling company client.

The single shale shaker with splash proof cover to prevent drilling fluids splashing, the control panel is installed on one side of possum belly for convenient operation. The feeding drilling fluids received from wellhead will flow to 3 shale shakers evenly for better drilling fluids separation. The solids discharge way can be bottom discharge and side discharge for option. 2ea vibration motors produce high vibration G force up to 7.6G which drived the shale shaker vibration in linear motion, the patent design deck bottom sealing rubber strip provide better sealing performance, to prevent fluids leakage to mud tank. The composite material shaker screen is installed on the shale shaker for longer working life, and reduce the time and cost to replace damaged shaker screens.

Recently GNSP-40B and GNSP-10B sludge vacuum pumps are ready for shipment for drilling waste cleaning to Africa. The application of vacuum pump used at drilling rig site including: drilling hazardous waste cleaning, waste pit cleaning, mud tank cleaning, drilling rig platform cleaning, drilling cuttings transfer, etc.

When the vacuum pump is used as drilling cuttings transfer, it can be used as screw conveyor, which will collect the drilling cuttings from primary solids control equipments, such as shale shaker, desander, desilter, decanter centrifuge, etc. The usage of vacuum pump and screw conveyor is according to space limitation, vacuum pump needs less space for installation, the max suction distance is 50m, the max discharge distance is up to 1000m, it is 100% air operation pump without electricity power supply, just it needs air compressor for air supply. The screw conveyor needs large area for installation, and the transfer distance is very limited, and the power consumption is also high. In actual situation, the user can use both vacuum pump and screw conveyor together, the drilling waste is collected in a collection hopper by vacuum pump and transferred by screw conveyor to drilling cuttings treatment system vertical cuttings dryer and decanter centrifuge for drilling cuttings treatment and cleaning.

When the vacuum pump is used for drilling waste and waste pit cleaning, there are automatic mode and manual mode for option, and connect suction pipe, discharge pipe and air hose with air compressor, if automatic mode is selected, set the suction and discharge time after running the vacuum pump for several loops. The maximum solids size for GNSP40B vacuum pump is up to 75mm, waste solids content is up to 80%.We also provide different type suction pipe and discharge pipe to transfer different waste material with different length, each section length is 10m with joint.

3 packages of drilling rig solids control equipments are ready for delivery to South America customer. The equipments list including:

1) GNZS594J-SHBJ linear motion shale shaker, 12 units, each rig 4 sets of shale shaker, 3 units as main use shale shaker, 1 unit as back up shale shaker. The shaker screens installed on the shale shaker and mud cleaner are with same dimension 585x1165mm, which is produced comply with API RP13C standard, 3 layers wire mesh for API 60 and above for longer screen life, high quality fiber glass to improve plastic quality and screen temperature resistant to 140℃.

2) GNZJ594J-3S16N linear motion mud cleaner, 3 units, with 3 ea of 10 inch desander cone and 16 ea of 4 inch desilter cone, treating capacity is up to 1500gpm. All of the hydrocyclones are made of 100% polyurethane material for better abrasion resistance.
3) GNSB8X6-13J centrifugal pump as feeding pump of desander cone and desilter cone, 6 units
4) 3 units of middle speed decanter centrifuge with its feeding pump GNG30-075C, for barite recovery
5) 3 units of high speed decanter centrifuge with its feeding pump GNG30-075C, for low gravity solids separation

6) Explosion proof control panel of centrifugal pump 55KW
The equipments are with customized painting color and client’s LOGO. All of the equipments can be installed on the client’s mud tank and connected by bolts easily. If required, we can also design customized drilling rig solids control system for client’s different requirement.
Except for shale shaker, mud cleaner, decanter centrifuge, centrifugal pump, GN solids control also produce vacuum degasser, mud agitator, mud gun, mixing hopper, submersible slurry pump, mud tank, mud gas separator, etc. solids control equipments, we can also produce dewatering centrifuge, vertical cuttings dryer, screw conveyor, sludge vacuum pump, etc. drilling waste treatment equipments.

GN mining vibrating screen, shale shaker and decanter centrifuge, desilter cleaner are used for Australia construction mud treatment. The construction mud treatment system including:

Mining vibrating shaker , the function is to separate stones, construction waste, branches, etc., so that big solids will not be feed to further process and block the equipments.

The high frequency fine vibrating screen, the function is to separate the coarse solids and reduce solids content. The composite material frame shaker screen is used to separate the coarse solids from to construction mud. We can produce different API mesh size screen from API 20 to API 325 according to your requirement. The high frequency fine vibrating screen is designed for classification, separation and dewatering application of wet or dry screening.

Desilter mud cleaner, the function is to separate the fine solids from the construction mud, the separation cut point is 15~40 microns. The qty of desilter cone depends on required treating capacity. The bottom shaker installed composite material frame shaker screen for drying the discharged solids and recycle more useful fluids.

Decanter centrifuge, the function is to separate the fine solids cut point 2~5 microns, working with flocculants from chemical dosing unit, most of the ultra fine solids can be separated out, the recovery water can be reused or sent to waste water treatment plant for further treatment. The previous separation has separated most of the coarse solids and reduce solids content to proper content so that the centrifuge can work properly without blocking the screw.
The solids discharged from mining vibration shale shaker, high frequency fine vibrating screen shaker, desilter mud cleaner, decanter centrifuge can be collected by waste collection box and easily transported to other place. If you need a customized construction mud treatment plant, pls contact with GN solids control.
