Recently one set of GNTBM-240 TBM slurry separation plant are shipped to South America client, which is a compact designed slurry separation plant for our TBM project client.
The technical configuration is as below:
Model: GNTBM-240

Treating capacity: 240m3/h (1000gpm)
(Desander) Mud cleaner: GNZY705E-Y2S, which is a double deck shale shaker with 2 ea of 10 inch desander cone, the double deck shale shaker with coarse screen( bottom layer) area is 2.63m2 , the fine screen( top layer) area is 1.35m2. The vibration strength is 7.5G, which is adjustable.
(Desilter) Mud cleaner:GNZY752E-Y12N, which is a single deck shale shaker with 12 ea of 4 inch desilter cone, the fine screen( dewatering screen) area is 1.35m2, total dewatering screen area is 2.7m2.
The feeding pump of desander, desilter is 55KW centrifugal pump, GNSB8X6-13J, the centrifugal pump produced by GN Solids is interchangeable with Mission pump. The total power consumption is 116KW, the shipping dimension is 6058x2438x2591mm, the user can transport it by 20ft container trailer with container fixing corner.

The complete GNTBM-240 TBM slurry separation plant with 2 layers installation, the bottom later installed one unit of desander cleaner, the desilter cleaner is installed on the top layer. The system control system are installed on the fluids catching tank which is on the skid, the whole system are in a 20ft container frame, the user can lift it or move it easily with the standard 20ft container frame. The control panel are installed in the front side of the complete system for convenient operation.
Except for the TBM slurry separation plant, GN solids control can also produce mud recycling system for HDD, CBM & Geothermal, water well drilling, and desander unit for Piling works and micron tunneling. If you need a customized solution for your slurry separation projects, pls contact with GN solids control.
GNTBM-240

GN solids control can provide customized solution for both oil based drilling cuttings treatment system and oil sludge separation unit, when the system is installed at the rig site, drilling waste management system is proper, when the system is installed in the waste treatment facility, both system can be installed, the customer can use one as per their requirement.

Drilling waste management system including major equipments- vertical cuttings dryer and decanter centrifuge, the oil based drilling cuttings can be transferred by screw conveyor or cuttings vacuum pump to the feeding port of vertical cuttings dryer, the screen basket trap wet solids and accelerate them up to 900rpm with G force up to 420G. the solids discharged from vertical cuttings dryer with OOC below than 5%, but oil content below 5% can not meet the disposal regulation in some countries, they need the oil content below 1%, the solids can be treated by burning unit or Thermal Desorption Unit, which can treat the solids with oil content below 0.3%. The mud treated by vertical cuttings dryer will flow to the intermediate tank, the centrifuge feeding pump transfer the fluids to decanter centrifuge, the separation cut point is 2 ~ 5 microns. The discharged solids can be back to circulation again.

Compared with oil sludge separation unit, the drilling waste management system is with high efficiency, the treating capacity is up to 40m3/h, the oil sludge separation unit with treating capacity 1m3/h, 5m3/h, 15m3/h. the operatio cost is higher.
When the waste is mixed with water based mud drilling waste and oil based mud drilling waste, and the waste is not only from shale shaker, desander, but also from desilter, decanter centrifuge, with much fine solids in the waste, oil sludge separation unit is proper. If you need a customized solution for oil, water, solids separation solution, pls contact with GN freely.

Last week one batch of solids control equipments are shipped to Canada client, including shale shaker, mud cleaner and big bowl decanter centrifuge. The details are as below:

1) 2 sets pf 4 panel shale shaker, this is primary phase separation equipment, by using different API mesh size shaker screens, the client can separate different size solids from the drilling fluids, the 4 panel shaker screen effective screen area can reach 2.73m2, the 2 vibration motor drived the shale shaker and generate G force up to 8.0G. the shaker screen dimension is 585x1165mm, with composite material frame shaker screens. The shaker deck bottom is made of stainless steel for better corrosion resistance.

2) 1 set of 4 panel mud cleaner, which is a desander cone, desilter cone and bottom shale shaker 3 in 1 equipment, the bottom shale shaker model is exactly same with shale shaker, the client can make storage for only one size shaker screen and the spare parts are all universal.

3) 22 inch bowl decanter centrifuge: the big bowl decanter centrifuge with 22 inch bowl size and 71 inch bowl length, the normal working speed is 0~ 2500rpm, the max speed is 3000rpm, the max G force can reach 2719G, the separation cut point is 2 ~5 microns, the VFD control panel is positive pressurized VFD control pane with PLC touch screen, IEC ex for class 1 div 1 application, with main motor, back drive motor and pump motor inverter, the inverter are ABB drive.
These equipments will be used for their zero discharge system, a zero discharge system including solids control system and drilling waste management system, the shale shaker, mud cleaner and decanter centrifuge are major equipments for solids control system, the better performance of the solids control equipments, the less drilling waste produced, the high efficiency of drilling waste treatment system.

This week Friday and Saturday GN sales team finished Cooperation Development Training successfully. Our team total of 28 people, including all domestic sales and international sales staff, our destination is the scenic Yesanpo, which is a National AAAAA tourist area and World Geopark. The purpose is to improve the cohesion of the team, tap the sales passion of the members, thereby improving the sales ability of the team.

GN solids control is one of the solids control equipments and drilling waste management equipments in China, our products line including: shale shaker, mud cleaner, desander, desilter, vacuum degasser, decanter centrifuge, mixing hopper, jet mud mixer, mud agitator, mud gun, centrifugal pump, submersible slurry pump, vertical cuttings dryer, high G drying shaker, shaker screens, dewatering unit, oil sludge separation unit, screw conveyor, cuttings solidification unit, vacuum pump, vacuum unit.

The activity of the cooperation development training including:
1) Ice breaking and team culture construction:
2) The archery battlefield of attack & defense:
