One batch of jet mud mixer and vertical cuttings dryer are ready for shipment to our client in China.

The jet mud mixer is consist of mud mixing hopper and mud mixing pump, pipelines, valves, electric control panel on the oilfield skid, the mud mixing package can be easily connected with client’s old mud tank by flexible hose. The mixing hopper can be installed on top of mud tank, and install the mixing pump on the tank skid for better mixing efficiency.
Except for jet mud mixer, GN also produce other solids control equipments like shale shaker, mud cleaner, desander, desilter, vacuum degasser, centrifugal degasser, decanter centrifuge, mud gas separator, shaker screens, mud agitator, mud gun, centrifugal pump, submersible slurry pump, mud tank and flare ignition device. If you have requirement for a complete solids control system and mud recycling system, pls contact with GN solids control.

Vertical cuttings dryer is the core equipment for drilling waste management system, it is mainly used for oil based drilling cuttings treatment. The complete drilling waste management system for oil based drilling cuttings treatment including 1 ea vertical cuttings dryer, 1 ea decanter centrifuge, 1ea decanter centrifuge feeding pump ( screw pump), 1 ea flushing pump ( screw pump), telescopic skid for vertical cuttings dryer, telescopic skid for decanter centrifuge, complete package skid with intermediate tank, pipelines and accessories. The screw conveyor is installed horizontally to pick up drilling cuttings from solids control equipments, another unit is installed slantly to transfer the drilling cuttings to vertical cuttings dryer, the cuttings box or another unit auger to pick up the discharged solids and transfer to other place.
The fluids discharged from vertical cuttings dryer will flow to intermediate tank and the screw pump feed the fluids to decanter centrifuge for further treatment, the separation cut point is 2~5 microns.

As professional manufacturer of decanter centrifuge and sludge transfer pump in China, GN solids control can design complete waste water treatment system and supply single equipments to our target clients like environmental engineering company, so that they can make a mud tank system with accessories locally for less freight cost and importation cost.

Recently we shipped 2ea mini decanter centrifuges with centrifugal pump and sludge vacuum pump to our client environmental engineering client in the world. The 9 inch decanter centrifuge is the smallest model we can produce, we also have 14 inch bowl decanter centrifuge, 18 inch bowl decanter centrifuge, 22 inch bowl decanter centrifuge, 30 inch bowl decanter centrifuge for different industry. We have GNLW223D series with bowl length 26.4 inch, the ratio is 3, the max G force is 2492G, the max bowl speed is 4500rpm, the normal working speed is 3800rpm. GNLW224 series decanter centrifuge with ratio 4, the bowl length is 36.4 inch, the max speed is 5000 rpm, the normal working speed is 0 ~4500rpm, the max G force is 3077 G. We will select proper model decanter centrifuge for client’s different projects.

Normally we use screw pump as ideal feeding pump of decanter centrifuge, sometimes due to space limit and other consideration, we also use centrifugal pump and submersible slurry pump as centrifuge feeding pump, compare with screw pump, the slurry pump ’s flow rate can not be controlled by adjust the pump motor frequency, it can be adjusted by valves and installed a flow meter on the pump outlet, but the maintenance cost is cheaper, especially when solids content is very high, so the impeller and pump casing material should more abrasion resistance material.

Vacuum pump is used to transfer different types sludge, like industrial waste sludge, oil sludge, drilling cuttings, drilling fluids, etc.

Recently GN solids control shipped one set of CBM mud recycling system for coal exploration company. The technical configuration is as below:

1) Linear motion shale shaker 2 units: 3 panel shale shaker GNZS703F installed with 3pcs composite material frame shaker screens, we can produce API 20 to API 325 comply with API RP13C standard. Possum belly for the 2 units of shale shakers to collect sludge from drilling rig and distributor to 2 units shale shaker buffer box evenly. Each shale shaker is drived by 2 ea of Italy Oil brand vibration motors, GN own produced explosion proof starter is installed on the shale shaker. The function is to separate coarse solids from the coal slurry.

2) Desander with mini bottom shaker and centrifugal pump, 1ea of 10 inch desander cone installed on top of bottom shale shaker, the separation cut point is 45 microns
3) Desilter with mini bottom shaker and centrifugal pump, 8ea of 4 inch desilter cone installed on top of bottom shale shaker, the separation cut point is 20 microns

4) Mud tank system with tank accessories, as mud agitator, mud gun, walkway, handrails, stairs, pipelines, man hole, electric control system, clean gate, high position valves, we will design customized tank dimension according to the required capacity and installed equipments
5) Jet mud mixer, which is composed of mixing hopper, mixing pump, pipelines, valves and control panel on one skid.
6) Middle speed decanter centrifuge for barite recovery, the working speed is 1800rpm, the separation cut point is 5 ~7 microns.
7) One unit of slug tank with mud agitator are lay on the tank
GN solids control can design and produce solids control system / mud recycling system for oil & gas drilling, CBM, HDD, pls contact with GN solids sales for more information.
